This PR introduces a new, toplevel-only, syntax form :worldinc that semantically represents the effect of raising the current task's world age to the latest world for the remainder of the current toplevel evaluation (that context being an entry to eval or a module expression). For detailed motivation on why this is desirable, see #55145, which I won't repeat here, but the gist is that we never really defined when world-age increments and worse are inconsistent about it. This is something we need to figure out now, because the bindings partition work will make world age even more observable via bindings.

Having created a mechanism for world age increments, the big question is one of policy, i.e. when should these world age increments be inserted.

Several reasonable options exist:

  1. After world-age affecting syntax constructs (as proprosed in Make precise semantics of world-age increments in top-level thunks #55145)
  2. Option 1 + some reasonable additional cases that people rely on
  3. Before any top level call expression
  4. Before any expression at toplevel whatsover

As an example, case, consider a == a at toplevel. Depending on the semantics that could either be the same as in local scope, or each of the four world age dependent lookups (three binding lookups, one method lookup) could (potentially) occur in a different world age.

The general tradeoff here is between the risk of exposing the user to confusing world age errors and our ability to optimize top-level code (in general, any :worldinc statement will require us to fully pessimize or recompile all following code).

This PR basically implements option 2 with the following semantics:

  1. The interpreter explicit raises the world age only at :worldinc exprs or after :module exprs.
  2. The frontend inserts :worldinc after all struct definitions, method definitions, using and `import.
  3. The @eval macro inserts a worldinc following the call to eval if at toplevel
  4. A literal (syntactic) call to include gains an implicit worldinc.

Of these the fourth is probably the most questionable, but is necessary to make this non-breaking for most code patterns. Perhaps it would have been better to make include a macro from the beginning (esp because it already has semantics that look a little like reaching into the calling module), but that ship has sailed.

Unfortunately, I don't see any good intermediate options between this PR and option #3 above. I think option #3 is closest to what we have right now, but if we were to choose it and actually fix the soundness issues, I expect that we would be destroying all performance of global-scope code. For this reason, I would like to try to make the version in this PR work, even if the semantics are a little ugly.

The biggest pattern that this PR does not catch is:

eval(:(f() = 1))
f()

We could apply the same include special case to eval, but given the existence of @eval which allows addressing this at the macro level, I decided not to. We can decide which way we want to go on this based on what the package ecosystem looks like.

The SparseArrays test failure is known - SparseArrays.allowscalar redefines indexing methods and the test relies on that getting picked up right away. Should be changed to a macro with a worldage increment probably, but before going through the hassle of the multi repo coordination, let's finish this PR.

I’m not opposed to this PR, but what’s the specific reason for introducing :worldinc? From what I understand from reading #55145, it seems like modifying the runtime to adhere to these rules would avoid the discussed issues?

We stop incrementing the world age for every statement. Instead, world age (at the toplevel) is incremented to the latest world age only at the following points:
a. Entry into toplevel evaluation (i.e., at the beginning of Core.eval)
b. After any evaluation of :method
c. On the bindings branch, after introducing a new binding

(plus an increment after a :module expression as per you mentioned above)

That said, I think introducing :worldinc would make it easier to fix inference-related problems, like ensuring world-age is incremented correctly for include as done in this PR. So I’m actually in favor of adding this expression type, but I’d like to understand the reasoning clearly.

Does this mean that the result of Base.delete_method (and Base.delete_binding) won’t take effect until the user explicitly calls Core.@worldinc? That sounds like it would be a pretty breaking change. I agree with the idea of restricting the effect of :worldinc to the top level (for helping inference), but it seems like Base.delete_method might need some adjustments, such as calling @eval internally or something similar.

It takes effect immediately (in a new world age), but the effect is not visible in the current task until it raises it world age.

Calling @eval internally will not raise the world age, because it's not at top level. delete_method is mostly used internally by Revise which can take an appropriate adjustment. There could also be a delete_method macro that does the world age raising implicitly.

Two reasons:

  1. As a separation of concerns issue and to put the more complicated world-age increment decisions into lowering rather than forcing the logic to be duplicated in several places
  2. To enable it to be inserted by macros that may want it

Forgot to mention that @vtjnash pointed out that I already made world age increment for macro purposes in #53515, so it would be inconsistent for it not to increment the world age for execution, which I found convincing.

Alright, a fair number of tests with dependencies on JuliaInterpreter or Revise, which need to be taught about :worldinc, but also some that noticed the behavior change. I think the thing to do is

  1. an independent PR that just introduces :worldinc, but doesn't use it yet
  2. Fix JuliaInterpreter/Revise
  3. Re-run PkgEval and see what to do about the rest of the packages

This was part of #56509, but is an independent bugfix. The basic
issue is that these macro were using `do` block internally. This
is undesirable for test macros, because we would like them not to
affect the behavior of what they're testing. E.g. right now:
```

Overall SGTM (though needs a rebase against the parts that are merged already).

Looks like a lot of the needed added Core.@worldinc also will be already solved by making each toplevel / module statement continue to imply an updated world (since they already imply an updated macro world, and the statements are supposed to run in the world after that macro expansion, which wouldn't be possible to express with these explicit markers anyways)

One other remaining todo item is adding this to the Compiler verifier code. I don't know if we run any debug tests on PRs, but I believe we run those on nightly, and it likely should error on the unexpected Expr head.

* Fix scope of hoisted signature-local variables (#56712)

When we declare inner methods, e.g. the `f` in

```
function fs()
   f(lhs::Integer) = 1
   f(lhs::Integer, rhs::(local x=Integer; x)) = 2
   return f
end
```

we must hoist the definition of the (appropriately mangled) generic
function `f` to top-level, including all variables that were used in the
signature definition of `f`. This situation is a bit unique in the
language because it uses inner function scope, but gets executed in
toplevel scope. For example, you're not allowed to use a local of the
inner function in the signature definition:

```
julia> function fs()
          local x=Integer
          f(lhs::Integer, rhs::x) = 2
          return f
       end
ERROR: syntax: local variable x cannot be used in closure declaration
Stacktrace:
 [1] top-level scope
   @ REPL[3]:1
```

In particular, the restriction is signature-local:
```
julia> function fs()
          f(rhs::(local x=Integer; x)) = 1
          f(lhs::Integer, rhs::x) = 2
          return f
       end
ERROR: syntax: local variable x cannot be used in closure declaration
Stacktrace:
 [1] top-level scope
   @ REPL[4]:1
```

There's a special intermediate form `moved-local` that gets generated
for this definition. In c6c3d72d1cbddb3d27e0df0e739bb27dd709a413, this
form stopped getting generated for certain inner methods. I suspect this
happened because of the incorrect assumption that the set of moved
locals is being computed over all signatures, rather than being a
per-signature property.

The result of all of this was that this is one of the few places where
lowering still generated a symbol as the lhs of an assignment for a
global (instead of globalref), because the code that generates the
assignment assumes it's a local, but the later pass doesn't know this.
Because we still retain the code for this from before we started using
globalref consistently, this wasn't generally causing a problems, except
possibly leaking a global (or potentially assigning to a global when
this wasn't intended). However, in follow on work, I want to make use of
knowing whether the LHS is a global or local in lowering, so this was
causing me trouble.

Fix all of this by putting back the `moved-local` where it was dropped.

Fixes #56711

* ircode: avoid serializing ssaflags in the common case when they are all zero

When not all-zero, run-length encoding would also probably be great
here for lowered code (before inference).

* Extend `invoke` to accept CodeInstance (#56660)

This is an alternative mechanism to #56650 that largely achieves the
same result, but by hooking into `invoke` rather than a generated
function. They are orthogonal mechanisms, and its possible we want both.
However, in #56650, both Jameson and Valentin were skeptical of the
generated function signature bottleneck. This PR is sort of a hybrid of
mechanism in #52964 and what I proposed in
https://github.com/JuliaLang/julia/pull/56650#issuecomment-2493800877.

In particular, this PR:

1. Extends `invoke` to support a CodeInstance in place of its usual
`types` argument.

2. Adds a new `typeinf` optimized generic. The semantics of this
optimized generic allow the compiler to instead call a companion
`typeinf_edge` function, allowing a mid-inference interpreter switch
(like #52964), without being forced through a concrete signature
bottleneck. However, if calling `typeinf_edge` does not work (e.g.
because the compiler version is mismatched), this still has well defined
semantics, you just don't get inference support.

The additional benefit of the `typeinf` optimized generic is that it
lets custom cache owners tell the runtime how to "cure" code instances
that have lost their native code. Currently the runtime only knows how
to do that for `owner == nothing` CodeInstances (by re-running
inference). This extension is not implemented, but the idea is that the
runtime would be permitted to call the `typeinf` optimized generic on
the dead CodeInstance's `owner` and `def` fields to obtain a cured
CodeInstance (or a user-actionable error from the plugin).

This PR includes an implementation of `with_new_compiler` from #56650.
This PR includes just enough compiler support to make the compiler
optimize this to the same code that #56650 produced:

```
julia> @code_typed with_new_compiler(sin, 1.0)
CodeInfo(
1 ─      $(Expr(:foreigncall, :(:jl_get_tls_world_age), UInt64, svec(), 0, :(:ccall)))::UInt64
│   %2 =   builtin Core.getfield(args, 1)::Float64
│   %3 =    invoke sin(%2::Float64)::Float64
└──      return %3
) => Float64
```

However, the implementation here is extremely incomplete. I'm putting it
up only as a directional sketch to see if people prefer it over #56650.
If so, I would prepare a cleaned up version of this PR that has the
optimized generics as well as the curing support, but not the full
inference integration (which needs a fair bit more work).

* Update references to LTS from v1.6 to v1.10 (#56729)

* lowering: Canonicalize to builtins for global assignment (#56713)

This adjusts lowering to emit `setglobal!` for assignment to globals,
thus making the `=` expr head used only for slots in `CodeInfo` and
entirely absent in `IRCode`. The primary reason for this is just to
reduce the number of special cases that compiler passes have to reason
about. In IRCode, `=` was already essentially equivalent to
`setglobal!`, so there's no good reason not to canonicalize.

Finally, the `=` syntax form for globals already gets recognized
specially to insert `convert` calls to their declared binding type, so
this doesn't impose any additional requirements on lowering to
distinguish local from global assignments. In general, I'd also like to
separate syntax and intermediate forms as much as possible where their
semantics differ, which this accomplises by just using the builtin.

This change is mostly semantically invisible, except that spliced-in
GlobalRefs now declare their binding because they are indistinguishable
from ordinary assignments at the stage where I inserted the lowering. If
we want to, we can preserve the difference, but it'd be a bit more
annoying for not much benefit, because:
1. The spliced in version was only recently made to work anyway, and
2. The semantics of when exactly bindings are declared is still messy on
master anyway and will get tweaked shortly in further binding partitions
work.

still rounds up to 32).

There was also no reason for InferenceState to be mutating of CodeInfo

* Hide IRShow include from Revise (#56756)

Revise in theory wants to re-evaluate this include, but it fails at
doing so, because the include call no longer works after bootstrap. It
happens to work right now on master, because the lowering of
`Compiler.include` happens to hide the include call from Revise, but
that's a Revise bug I'm about to fix. Address this by moving the include
call into the package and using an absolute include if necessary.

* fixup!: JuliaLang/julia#56756 (#56758)

We need to quote it, otherwise it would result in `UnderVarError`.

* Accept more general Integer sizes in reshape (#55521)

This PR generalizes the `reshape` methods to accept `Integer`s instead
of `Int`s, and adds a `_reshape_uncolon` method for `Integer` arguments.
The current `_reshape_uncolon` method that accepts `Int`s is left
unchanged to ensure that the inferred types are not impacted. I've also
tried to ensure that most `Integer` subtypes in `Base` that may be
safely converted to `Int`s pass through that method.

The call sequence would now go like this:
```julia
reshape(A, ::Tuple{Vararg{Union{Integer, Colon}}}) -> reshape(A, ::Tuple{Vararg{Integer}}) -> reshape(A, ::Tuple{Vararg{Int}}) (fallback)
```
This lets packages define `reshape(A::CustomArray, ::Tuple{Integer,
Vararg{Integer}})` without having to implement `_reshape_uncolon` by
themselves (or having to call internal `Base` functions, as in
https://github.com/JuliaArrays/FillArrays.jl/issues/373). `reshape`
calls involving a `Colon` would convert this to an `Integer` in `Base`,
and then pass the `Integer` sizes to the custom method defined in the
package.

This PR does not resolve issues like
https://github.com/JuliaLang/julia/issues/40076 because this still
converts `Integer`s to `Int`s in the actual reshaping step. However,
`BigInt` sizes that may be converted to `Int`s will work now:
```julia
julia> reshape(1:4, big(2), big(2))
2×2 reshape(::UnitRange{Int64}, 2, 2) with eltype Int64:
 1  3
 2  4

julia> reshape(1:4, big(1), :)
1×4 reshape(::UnitRange{Int64}, 1, 4) with eltype Int64:
 1  2  3  4
```

Note that the reshape method with `Integer` sizes explicitly converts
these to `Int`s to avoid self-recursion (as opposed to calling
`to_shape` to carry out the conversion implicitly). In the future, we
may want to decide what to do with types or values that can't be
converted to an `Int`.

* drop llvm 16 support (#56751)

Co-authored-by: Valentin Churavy <[email protected]>

* Address some post-commit review from #56660 (#56747)

Some more questions still to be answered, but this should address the
immediate actionable review items.

* Add per-task metrics (#56320)

Close https://github.com/JuliaLang/julia/issues/47351 (builds on top of
https://github.com/JuliaLang/julia/pull/48416)

Adds two per-task metrics:
- running time = amount of time the task was actually running (according
to our scheduler). Note: currently inclusive of GC time, but would be
good to be able to separate that out (in a future PR)
- wall time = amount of time between the scheduler becoming aware of
this task and the task entering a terminal state (i.e. done or failed).

We record running time in `wait()`, where the scheduler stops running
the task as well as in `yield(t)`, `yieldto(t)` and `throwto(t)`, which
bypass the scheduler. Other places where a task stops running (for
`Channel`, `ReentrantLock`, `Event`, `Timer` and `Semaphore` are all
implemented in terms of `wait(Condition)`, which in turn calls `wait()`.
`LibuvStream` similarly calls `wait()`.

This should capture everything (albeit, slightly over-counting task CPU
time by including any enqueuing work done before we hit `wait()`).

The various metrics counters could be a separate inlined struct if we
think that's a useful abstraction, but for now i've just put them
directly in `jl_task_t`. They are all atomic, except the
`metrics_enabled` flag itself (which we now have to check on task
start/switch/done even if metrics are not enabled) which is set on task
construction and marked `const` on the julia side.

In future PRs we could add more per-task metrics, e.g. compilation time,
GC time, allocations, potentially a wait-time breakdown (time waiting on
locks, channels, in the scheduler run queue, etc.), potentially the
number of yields.

Perhaps in future there could be ways to enable this on a per-thread and
per-task basis. And potentially in future these same timings could be
used by `@time` (e.g. writing this same timing data to a ScopedValue
like in https://github.com/JuliaLang/julia/pull/55103 but only for tasks
lexically scoped to inside the `@time` block).

Timings are off by default but can be turned on globally via starting
Julia with `--task-metrics=yes` or calling
`Base.Experimental.task_metrics(true)`. Metrics are collected for all
tasks created when metrics are enabled. In other words,
enabling/disabling timings via `Base.Experimental.task_metrics` does not
affect existing `Task`s, only new `Task`s.

The other new APIs are `Base.Experimental.task_running_time_ns(::Task)`
and `Base.Experimental.task_wall_time_ns(::Task)` for retrieving the new
metrics. These are safe to call on any task (including the current task,
or a task running on another thread). All these are in
`Base.Experimental` to give us room to change up the APIs as we add more
metrics in future PRs (without worrying about release timelines).

* Fully outline all GlobalRefs (#56746)

This is an alternative to #56714 that goes in the opposite direction -
just outline all GlobalRefs during lowering. It is a lot simpler that
#56714 at the cost of some size increase. Numbers:

sys.so .ldata size:
This PR: 159.8 MB
Master: 158.9 MB

I don't have numbers of #56714, because it's not fully complete.
Additionally, it's possible that restricting GlobalRefs from arguments
position would let us use a more efficient encoding in the future.

* Add #54800 to NEWS (#56774)

* Add the actual datatype to the heapsnapshot. This groups objects of the same type together (#56596)

* Fix typos in docstring, comments, and news (#56778)

* Add sort for NTuples (#54494)

This is partially a reland of #46104, but without the controversial `sort(x) = sort!(copymutable(x))` and with some extensibility improvements. Implements #54489.

* precompile: don't waste memory on useless inferred code (#56749)

We never have a reason to reference this data again since we already
have native code generated for it, so it is simply wasting memory and
download space.

* various globals cleanups (#56750)

While doing some work on analyzing what code runs at toplevel, I found a
few things to simplify or fix:

- simplify float.jl loop not to call functions just defined to get back
the value just stored there
- add method to the correct checkbounds function (instead of a local)
- missing world push/pop around jl_interpret_toplevel_thunk after #56509
- jl_lineno use maybe missed in #53799
- add some debugging dump for scm_to_julia_ mistakes

Fix `exp(reinterpret(Float64, 0x7ffbb14880000000))` returning non-NaN
value. This should have minimal performance impact since it's already in
the fallback branch.

* Add note to Vararg/UnionAll warning about making it an error (#56662)

This warning message
```
WARNING: Wrapping `Vararg` directly in UnionAll is deprecated (wrap the tuple instead).
You may need to write `f(x::Vararg{T})` rather than `f(x::Vararg{<:T})` or `f(x::Vararg{T}) where T` instead of `f(x::Vararg{T} where T)`.
```
(last extended in #49558) seems clear enough if you wrote the code. But
if it's coming from 10 packages deep, there's no information to track
down the origin.

Turns out you can do this with `--depwarn=error`. But the message
doesn't tell you that, and doesn't call itself a deprecation warning at
all.

* Add a note clearifying option parsing (#56285)

To help with #56274

* Fix undefined symbol error in version script (#55363)

lld 17 and above by default error if symbols listed in the version
script are undefined. Julia has a few of these, as some symbols are
defined conditionally in Julia (e.g. based on OS), others perhaps have
been removed from Julia and other seem to be defined in other libraries.
Further the version script is used in linking three times, each time
linking together different objects and so having different symbols
defined.

Adding `-Wl,--undefined-version` is not a great solution as passing that
to ld < 2.40 errors and there doesn't seem to be a great way to check if
a linker supports this flag.
I don't know how to get around these errors for symbols like
`_IO_stdin_used` which Julia doesn't define and it seems to matter
whether or not they are exported, see
https://libc-alpha.sourceware.narkive.com/SevIQmU3/io-stdin-used-stripped-by-version-scripts.
So I've converted all undefined symbols into wildcards to work around
the error.

Fixes #50414, fixes #54533 and replaces #55319.

I didn't succeed in making a test for this. The sole trigger seems to be
```julia
using HMMGradients
T = Float32
A = T[0.0 1.0 0.0; 0.0 0.5 0.5; 1.0 0.0 0.0]
t2tr = Dict{Int,Vector{Int}}[Dict(1 => [2]),]
t2IJ= HMMGradients.t2tr2t2IJ(t2tr)

Nt = length(t2tr)+1
Ns = size(A,1)
y = rand(T,Nt,Ns)

c = rand(Float32, Nt)
beta = backward(Nt,A,c,t2IJ,y)
gamma = posterior(Nt,t2IJ,A,y)
```

One other option is to have the builtin handle receiving a CI. That
might make the code cleaner and does handle the case where we receive a
dynamic CI (is that even a thing)

* make `memorynew` intrinsic (#56803)

Attempt to split up https://github.com/JuliaLang/julia/pull/55913 into 2
pieces. This piece now only adds the `memorynew` intrinsic without any
of the optimizations enabled by
https://github.com/JuliaLang/julia/pull/55913. As such, this PR should
be ready to merge now. (and will make
https://github.com/JuliaLang/julia/pull/55913 smaller and simpler)

* fix `compute_trycatch` for `IRCode` /w `EnterNode` with `catch_dest==0` (#56846)

* EA: general cleanup (#56848)

The handling of `Array` in EA was implemented before `Memory` was
introduced and has now become stale. Analysis for `Array` should be
reintroduced after the upcoming overhaul is completed. For now, I will
remove the existing stale code.

Fix #56841.

Currently the documentation states that keys(dict) and values(dict)

order as that used by pairs(dict), or when looping, for (k,v) in dict.

This PR makes this guarantee explicit.

               mi = codeinst
           else
               codeinst::Core.CodeInstance
               mi = codeinst.def

           return mi
       end == Core.MethodInstance
Test Passed
```

* EA: use embedded `CodeInstance` directly for escape cache lookup (#56860)

* Compiler.jl: use `Base.[all|any]` instead of `Compiler`'s own versions (#56851)

The current `Compiler` defines its own versions of `all` and `any`,
which are separate generic functions from `Base.[all|any]`:
https://github.com/JuliaLang/julia/blob/2ed1a411e0a080f3107e75bb65105a15a0533a90/Compiler/src/utilities.jl#L15-L32

On the other hand, at the point where `Base.Compiler` is bootstrapped,
only a subset of `Base.[all|any]` are defined, specifically those
related to `Tuple`:

https://github.com/JuliaLang/julia/blob/2ed1a411e0a080f3107e75bb65105a15a0533a90/base/tuple.jl#L657-L668.
Consequently, in the type inference world, functions like
`Base.all(::Generator)` are unavailable. If `Base.Compiler` attempts to
perform operations such as `::BitSet ⊆ ::BitSet` (which internally uses
`Base.[all|any]`), a world age error occurs (while `Compiler.[all|any]`
can handle these operations, `::BitSet ⊆ ::BitSet` uses
`Base.[all|any]`, leading to this issue)

To resolve this problem, this commit removes the custom `Compiler`
versions of `[all|any]` and switches to using the Base versions.

One concern is that the previous `Compiler` versions of `[all|any]`
utilized `@nospecialize`. That annotation was introduced a long time ago
to prevent over-specialization, but it is questionable whether it is
still effective with the current compiler implementation. The results of
the nanosoldier benchmarks conducted below also seem to confirm that
the `@nospecialize`s are no longer necessary for those functions.

* Extend `Base.rationalize` instead of defining new function (#56793)

#55886 accidentally created a new function
`Base.MathConstants.rationalize` instead of extending
`Base.rationalize`, which is the reason why `Base.rationalize(Int, π)`
isn’t constant-folded in Julia 1.10 and 1.11:

```
julia> @btime rationalize(Int,π);
  1.837 ns (0 allocations: 0 bytes)      # v1.9: constant-folded
  88.416 μs (412 allocations: 15.00 KiB) # v1.10: not constant-folded
```

This PR fixes that. It should probably be backported to 1.10 and 1.11.

* Add ABIOverride type for def field (#56555)

Together with #54899, this PR is intending to replicate the
functionality of #54373, which allowed particular specializations to
have a different ABI signature than what would be suggested by the
MethodInstance's `specTypes` field. This PR handles that by adding a
special `ABIOverwrite` type, which, when placed in the `owner` field of
a `CodeInstance` instructs the system to use the given signature
instead.

* EAUtils: perform `code_escapes` with a global cache by default (#56868)

In JuliaLang/julia#56860, `EAUtils.EscapeAnalyzer` was updated to create
a new cache for each invocation of `code_escapes`, similar to how
Cthulhu.jl behaves. However, `code_escapes` is often used for
performance analysis like `@benchmark code_escapes(...)`, and in such
cases, a large number of `CodeInstance`s can be generated for each
invocation. This could potentially impact native code execution.

So this commit changes the default behavior so that `code_escapes` uses
the same pre-existing cache by default. We can still opt-in to perform a
fresh analysis by specifying
`cache_token=EAUtils.EscapeAnalyzerCacheToken()`.

* Small ABIOverride follow up and add basic test (#56877)

Just a basic `invoke` test for now. There's various other code paths
that should also be tested with ABI overwrites, but this gives us the
basic framework and more tests can be added as needed.

I think this makes it a bit less technical (the word "Displaying" and
the long filename), and it improves the reading flow.

* Support indexing `Broadcasted` objects using `Integer`s (#56470)

This adds support for `IndexLinear` `eachindex`, as well as
bounds-checking and `getindex` for a `Broadcasted` with an `Integer`
index.

Instead of using the number of dimensions in `eachindex` to determine
whether to use `CartesianIndices`, we may use the `IndexStyle`. This
should not change anything currently, but this adds the possibility of
`nD` broadcasting using linear indexing if the `IndexStyle` of the
`Broadcasted` object is `IndexLinear`.

After this,
```julia
julia> bc = Broadcast.broadcasted(+, reshape(1:4, 2, 2), 1:2)
Base.Broadcast.Broadcasted(+, ([1 3; 2 4], 1:2))

julia> eachindex(bc)
CartesianIndices((2, 2))

julia> eachindex(IndexLinear(), bc)
Base.OneTo(4)

julia> [bc[I] for I in eachindex(IndexLinear(), bc)]
4-element Vector{Int64}:
 2
 4
 4
 6

julia> vec(collect(bc))
4-element Vector{Int64}:
 2
 4
 4
 6
```

This PR doesn't add true linear indexing support for `IndexCartesian`
`Broadcasted` objects. In such cases, an `Integer` index is converted to
a `CartesianIndex` before it is used in indexing.

* Limit the scope of `@inbounds` in `searchsorted*` (#56882)

This removes bounds-checking only in the indexing operation, instead of
for the entire block.

* Remove trailing comma in 0-dim `reshape` summary (#56853)

Currently, there is an extra comma in displaying the summary for a 0-dim
`ReshapedArray`:
```julia
julia> reshape(1:1)
0-dimensional reshape(::UnitRange{Int64}, ) with eltype Int64:
1
```
This PR only prints the comma if `dims` isn't empty, so that we now
obtain
```julia
julia> reshape(1:1)
0-dimensional reshape(::UnitRange{Int64}) with eltype Int64:
1
```

* Switch debug registry mapping to `CodeInstance` (#56878)

Currently our debugging code maps from pointers to `MethodInstance`.
However, I think it makes more sense to map to `CodeInstance` instead,
since that's what we're actually compiling and as we're starting to make
more use of external owners and custom specializations, we'll want to be
able to annotate that in backtraces. This only adjusts the internal data
structures - any actual printing changes for those sorts of use cases
will have to come separately.

* Remove `similar` specialization with `Integer`s (#56881)

This method seems unnecessary, as the method on line 830 does the same
thing. Having this method in `Base` requires packages to disambiguate
against this by adding redundant methods.

* simplify  and slightly improve memorynew inference (#56857)

while investigating some missed optimizations in
https://github.com/JuliaLang/julia/pull/56847, @gbaraldi and I realized
that `copy(::Array)` was using `jl_genericmemory_copy_slice` rather than
the `memmove`/`jl_genericmemory_copyto` that `copyto!` lowers to. This
version lets us use the faster LLVM based Memory initialization, and the
memove can theoretically be further optimized by LLVM (e.g. not copying
elements that get over-written without ever being read).

```
julia> @btime copy($[1,2,3])
  15.521 ns (2 allocations: 80 bytes) # before
  12.116 ns (2 allocations: 80 bytes) #after

julia> m = Memory{Int}(undef, 3);
julia> m.=[1,2,3];
julia> @btime copy($m)
  11.013 ns (1 allocation: 48 bytes) #before
  9.042 ns (1 allocation: 48 bytes)   #after
```

We also optimize the `memorynew` type inference to make it so that
getting the length of a memory with known length will propagate that
length information (which is important for cases like `similar`/`copy`
etc).

* Update the OffsetArrays test helper (#56892)

This updates the test helper to match v1.15.0 of `OffsetArrays.jl`. The
current version was copied over from v1.11.2, which was released on May
20, 2022, so this bump fetches the intermediate updates to the package.

The main changes are updates to `unsafe_wrap` and `reshape`. In the
latter, several redundant methods are now removed, whereas, in the
former, methods are added to wrap a `Ptr` in an `OffsetArray`
(https://github.com/JuliaArrays/OffsetArrays.jl/issues/275#issue-1222585268).
A third major change is that an `OffsetArray` now shares its parent's
`eltype` and `ndims` in the struct definition, whereas previously this
was ensured through the constructor. Other miscellaneous changes are
included, such as performance-related ones.

* fix: Base.GMP.MPZ.invert yielding return code instead of return value (#56894)

instead of the actual value. This commit fixes it.

* restrict `optimize_until` argument type correctly (#56912)

The object types that `optimize_until` can accept are restricted by
`matchpass`, so this restriction should also be reflected in functions
like `typeinf_ircode` too.

* doc: manual: give the Performance Tips a table of contents (#56917)

The page is quite long, and now it also has a more intricate structure
than before, IMO it deserves a TOC.

* ReentrantLock: wakeup a single task on unlock and add a short spin (#56814)

I propose a change in the implementation of the `ReentrantLock` to
improve its overall throughput for short critical sections and fix the
quadratic wake-up behavior where each unlock schedules **all** waiting
tasks on the lock's wait queue.

This implementation follows the same principles of the `Mutex` in the
[parking_lot](https://github.com/Amanieu/parking_lot/tree/master) Rust
crate which is based on the Webkit
[WTF::ParkingLot](https://webkit.org/blog/6161/locking-in-webkit/)
class. Only the basic working principle is implemented here, further
improvements such as eventual fairness will be proposed separately.

The gist of the change is that we add one extra state to the lock,
essentially going from:
```
0x0 => The lock is not locked
0x1 => The lock is locked by exactly one task. No other task is waiting for it.
0x2 => The lock is locked and some other task tried to lock but failed (conflict)
```
To:
```
# PARKED_BIT | LOCKED_BIT | Description
#     0      |     0      | The lock is not locked, nor is anyone waiting for it.
# -----------+------------+------------------------------------------------------------------
#     0      |     1      | The lock is locked by exactly one task. No other task is
#            |            | waiting for it.
# -----------+------------+------------------------------------------------------------------
#     1      |     0      | The lock is not locked. One or more tasks are parked.
# -----------+------------+------------------------------------------------------------------
#     1      |     1      | The lock is locked by exactly one task. One or more tasks are
#            |            | parked waiting for the lock to become available.
#            |            | In this state, PARKED_BIT is only ever cleared when the cond_wait lock
#            |            | is held (i.e. on unlock). This ensures that
#            |            | we never end up in a situation where there are parked tasks but
#            |            | PARKED_BIT is not set (which would result in those tasks
#            |            | potentially never getting woken up).
```

In the current implementation we must schedule all tasks to cause a
conflict (state 0x2) because on unlock we only notify any task if the
lock is in the conflict state. This behavior means that with high
contention and a short critical section the tasks will be effectively
spinning in the scheduler queue.

With the extra state the proposed implementation has enough information
to know if there are other tasks to be notified or not, which means we
can always notify one task at a time while preserving the optimized path
of not notifying if there are no tasks waiting. To improve throughput
for short critical sections we also introduce a bounded amount of
spinning before attempting to park.

### Results

Not spinning on the scheduler queue greatly reduces the CPU utilization
of the following example:

```julia
function example()
    lock = ReentrantLock()
    @sync begin
        for i in 1:10000
            Threads.@spawn begin
                @lock lock begin
                    sleep(0.001)
                end
            end
        end

Closes #56035.

* teach jitlayers to use equivalent edges

Sometimes an edge (especially from precompile file, but sometimes from
inference) will specify a CodeInstance that does not need to be compiled
for its ABI and simply needs to be cloned to point to the existing copy
of it.

* opaque_closure: fix data-race mistakes with reading fields by using standard helper function

* opaque_closure: fix world-age mistake in fallback path

This was failing the h_world_age test sometimes.

* inference,codegen: connect source directly to jit

This avoids unnecessary compression when running (not generating code).
While generating code, we continue the legacy behavior of storing
compressed code, since restarting from a ji without that is quite slow.
Eventually, we should also remove that code also once we have generated
the object file from it.

This replaces the defective SOURCE_MODE_FORCE_SOURCE option with a new
`typeinf_ext_toplevel` batch-mode interface for compilation which
returns all required source code. Only two options remain now:
SOURCE_MODE_NOT_REQUIRED :
    Require only that the IPO information (e.g. rettype and friends) is
    present.
SOURCE_MODE_FORCE_ABI :
    Require that the IPO information is present (for ABI computation)
    and that the returned CodeInstance can be invoked on the host target
    (preferably after inference, called directly, but perfectly
    acceptable for Base.Compiler to instead force the runtime to use a
    stub there or call into it with the interpreter instead by having
    failed to provide any code).

This replaces the awkward `jl_create_native` interface (which is now
just a shim for calling the new batch-mode `typeinf_ext_toplevel`) with
a simpler `jl_emit_native` API, which does not do any inference or other
callbacks, but simply is a batch-mode call to `jl_emit_codeinfo` and
the work to build the external wrapper around them for linkage.

* delete unused code, so the jit no longer uses the inferred field at all

* Make sure we don't promise alignments that are larger than the heap alignment to LLVM (#56938)

serenity4 pushed a commit to serenity4/julia that referenced this pull request May 1, 2025
This PR introduces a new, toplevel-only, syntax form `:worldinc` that
semantically represents the effect of raising the current task's world
age to the latest world for the remainder of the current toplevel
evaluation (that context being an entry to `eval` or a module
expression). For detailed motivation on why this is desirable, see
JuliaLang#55145, which I won't repeat here, but the gist is that we never really
defined when world-age increments and worse are inconsistent about it.
This is something we need to figure out now, because the bindings
partition work will make world age even more observable via bindings.

Having created a mechanism for world age increments, the big question is
one of policy, i.e. when should these world age increments be inserted.

Several reasonable options exist:
1. After world-age affecting syntax constructs (as proprosed in JuliaLang#55145)
2. Option 1 + some reasonable additional cases that people rely on
3. Before any top level `call` expression
4. Before any expression at toplevel whatsover

As an example, case, consider `a == a` at toplevel. Depending on the
semantics that could either be the same as in local scope, or each of
the four world age dependent lookups (three binding lookups, one method
lookup) could (potentially) occur in a different world age.

The general tradeoff here is between the risk of exposing the user to
confusing world age errors and our ability to optimize top-level code
(in general, any `:worldinc` statement will require us to fully
pessimize or recompile all following code).

This PR basically implements option 2 with the following semantics:

1. The interpreter explicit raises the world age only at `:worldinc`
exprs or after `:module` exprs.
2. The frontend inserts `:worldinc` after all struct definitions, method
definitions, `using` and `import.
3. The `@eval` macro inserts a worldinc following the call to `eval` if
at toplevel
4. A literal (syntactic) call to `include` gains an implicit `worldinc`.

Of these the fourth is probably the most questionable, but is necessary
to make this non-breaking for most code patterns. Perhaps it would have
been better to make `include` a macro from the beginning (esp because it
already has semantics that look a little like reaching into the calling
module), but that ship has sailed.

Unfortunately, I don't see any good intermediate options between this PR
and option JuliaLang#3 above. I think option JuliaLang#3 is closest to what we have right
now, but if we were to choose it and actually fix the soundness issues,
I expect that we would be destroying all performance of global-scope
code. For this reason, I would like to try to make the version in this
PR work, even if the semantics are a little ugly.

The biggest pattern that this PR does not catch is:
```
eval(:(f() = 1))
f()
```

We could apply the same `include` special case to eval, but given the
existence of `@eval` which allows addressing this at the macro level, I
decided not to. We can decide which way we want to go on this based on
what the package ecosystem looks like.

Covers JuliaLang/julia#56523, JuliaLang/julia#56509, JuliaLang/julia#57299.

Also includes changes from JuliaLang/julia#57102 (bpart: Start enforcing minimum
world age for const bparts) and JuliaLang/julia#57150 (bpart: Start enforcing
min_world for global variable definitions) since the lowering changes from those
appear to be amendments to the changes above (missing world age increments).

* Update CodeInfo struct and handling

Co-authored-by: Claire Foster <[email protected]>

* Don't produce raw symbol from globalref

This used to implicitly refer to a module-level name, but lowering is now
expected to wrap it in a `globalref`. Part of JuliaLang/julia#54772

* Updates to const and global lowering; add K"constdecl"; omit `wrap`

JuliaLang/julia#54773, JuliaLang/julia#56713, JuliaLang/julia#57470. Some
     changes omitted from `expand-decls` and `expand-assignment`.

Note that the two-argument IR "const" is K"constdecl", whereas the one-argument
    K"const" only appears in the AST.

Also note that the `wrap` parameter is omitted throughout assignment desugaring.
      As far as I'm aware, all this plumbing was just to support `const a,b,c =
     1,2,3` having `b` and `c` inherit the `const`.  TODO: find a better way of
     doing the same thing (a ScopedValue might be a clean solution; we currently
     throw an error).

The check for `let; const x = 1; end`, (which should throw) is in scope
     analysis (lisp has it in `compile`).

* Add `isdefinedglobal` builtin

JuliaLang/julia#54999, JuliaLang/julia#56985

* :global no longer valid_ir_argument; rm `is_defined_nothrow_global`

JuliaLang/julia#56746.  Also call :slot and :static_parameter valid (for now)

* Fix `is_defined_and_owned_global` (Core.Binding changes)

Adapt to bpart changes in JuliaLang/julia#54788

* Struct desugaring: "Undo decision to publish incomplete types..."

JuliaLang/julia#56497; Add self-referencing struct shim

I have doubts about how long this solution will stay in the base repository, and
     how complete it is (doesn't seem to work with M1.M2.S), but we are testing
     for it here.

Also change the expected value of a test changed in the same PR.

* Emit `latestworld` world age increments

For method defs, `latestworld` is produced in desugaring rather than closure
conversion for now (our closure conversion doesn't seem to cover the same
cases as lisp lowering yet).

Covers JuliaLang/julia#56523, JuliaLang/julia#56509, JuliaLang/julia#57299.

Also includes changes from JuliaLang/julia#57102 (bpart: Start enforcing minimum
world age for const bparts) and JuliaLang/julia#57150 (bpart: Start enforcing
min_world for global variable definitions) since the lowering changes from those
appear to be amendments to the changes above (missing world age increments).

* bpart changes: `Core._typebody!` signature

`Core._typebody!` now takes a new "prev" argument, which we don't use yet here.
 Changes from JuliaLang/julia#57253

* bpart changes: struct desugaring

Changes from JuliaLang/julia#57253 (bpart: Fully switch to partitioned
     semantics).  This fixes one failing test and realigns struct desugaring to
     match lisp for now.

Also changed: the expected result of redefining a primitive type (now allowed).

* Additional argument in `new_opaque_closure`

Fix segfaulting test.  Thanks for the TODO

* Adapt to different `GeneratedFunctionStub` signature

Signature changed in JuliaLang/julia#57230.  Thanks @aviatesk for the help!

* Fix `public` and `export`

As of JuliaLang/julia#57765, `jl_module_public` is no longer exported.  Change
our runtime to handle it like `public` and `export` like we handle `import`
or `using` for now

* Fix modules.jl test

I believe this was a world age issue

* Regenerate IR tests

Too many to count.

* Update README to known-good julia, JuliaSyntax versions

Latest julia works.  Changes are needed to work with the latest JuliaSyntax, but
     that isn't in base julia yet, and more changes are likely to come.

* Fix small bug from #16 so tests pass

The change lifted the scope of `note`, so it was being changed in the loop

* Changes from code review: const/global lowering

Ping me if you'd like this squashed into the original const/global commit!

Co-authored-by: Claire Foster <[email protected]>

* Remove a special case

No longer needed since we no longer put `global` or `local` forms back into the
     expand_forms machine.  Some error messages change slightly as a result.

* Changes from code review

Co-authored-by: Claire Foster <[email protected]>

* Fix + test for assignment in value but not tail position

* Disallow `static_parameter` as `valid_ir_argument`

See added comment, and discussion at
    #10 (comment)

* Change printing of `K"latestworld"`

Parens are nice, but it wasn't consistent.

Also make it a leaf (remaining non-leaves are deleted in the next commit.)

* Move most `latestworld`s to linearization

From the docs:
```
The following statements raise the current world age:
    1. An explicit invocation of Core.@latestworld
    2. The start of every top-level statement
    3. The start of every REPL prompt
    4. Any type or struct definition
    5. Any method definition
    6. Any constant declaration
    7. Any global variable declaration (but not a global variable assignment)
    8. Any using, import, export or public statement
    9. Certain other macros like eval (depends on the macro implementation)
```

This commit handles each case as follows:

```
    1. = 9
    2. I'm not sure this actually happens (or needs to happen, unless we're
       being defensive? Doing it after each world-changing operation should
       suffice).  But if we need it, this would just be emitting once at the
       beginning of every lowered output.
    3. = 2
    4. = 6
    5. Emit seeing `method` in linearize
    6. Emit seeing `constdecl` in linearize
    7. Emit seeing `global` or `globaldecl` in linearize
    8. We just defer to `eval`, but should probably go in desugaring later
       - using/import recently became builtin calls, and I haven't
         updated JL to use them yet.  Base._import_using has an expr-based
         API that may change, and our importpath destructuring is worth keeping.
       - export and public (special forms) are handled in toplevel.c
    9. Done for us
```

Other quirks:

- `JuliaLowering.eval_closure_type` calls eval to assign a const, so we still
    need to deal with that in closure conversion.

- The `include` hack isn't mentioned in the docs, but can stay in desugaring.
      I'm not certain why we don't do the same for non-macro `eval`.

* Use invokelatest after eval to adjust to upcoming julia change

In 1.12, we're cleaning up when implicit world age increments happen
at toplevel. Because these test `eval` an expression and immediately
call it, an `invokelatest` will likely be required (as it would be
right now in local scope). See JuliaLang/julia#56509

* Added note for future reference
