v0.10.0 panic with message TODO implement bigint to llvm int for 32-bit compiler builds

[prajwalch]

Zig Version

0.10.0

Steps to Reproduce and Observed Behavior

Got this error when i tried new version:

$ zig run main.zig

warning: Encountered error: FileNotFound, falling back to default ABI and dynamic linker.

thread 14753 panic: TODO implement bigint to llvm int for 32-bit compiler builds

And this when using fstage1

$ zig run main.zig -fstage1
warning: Encountered error: FileNotFound, falling back to default ABI and dynamic linker.

faced similar issue , on x64_linux using nix for building, also using the -fstage1

warning: Encountered error: FileNotFound, falling back to default ABI and dynamic linker.

and the result binary is not usable, seems the linker is not found and exe is not properly linked, with half the size

seems related to #12156

same behavior on a 32bit Debian netbook

I can not find the related TODO anymore and armv7 is provided as download option https://ziglang.org/download/, so I think this should be closed.

Hello, thanks! I can confirm that on 32-bit i386 linux it's fixed

I am still running into this, while compiling zls using the latest (armv7a-0.12.0-dev.589+731fd217d) Zig build.

This is on a Raspberry Pi 4: Linux phanpy 6.1.47-1-rpi-ARCH #1 SMP Fri Aug 25 13:19:49 MDT 2023 armv7l GNU/Linux

[matu3ba]

@koljakube The current version is in the range of "version": "0.12.0-dev.4922+c481510c9", which is ca. 4500 commits later than your mentioned commit.

rg -F 'TODO implement bigint to llvm int' has no results. Neither rg 'bigint to llvm'.

[leecannon]

@matu3ba the latest version on ziglang.org is zig-0.12.0-dev.589+731fd217d

[koljakube]

I just noticed I was wrong and did not properly compare error messages.

I am running into "TODO implement bigint debug enumerators to llvm int for 32-bit compiler builds", which is defined here (and is still in master).

Please disregard my previous comment.
