This commit adds support for column breakpoints to lldb-dap. To do so, support for the `breakpointLocations` request was added. To find all available breakpoint positions, we iterate over the line table. The `setBreakpoints` request already forwarded the column correctly to `SBTarget::BreakpointCreateByLocation`. However, `SourceBreakpointMap` did not keep track of multiple breakpoints in the same line. To do so, the `SourceBreakpointMap` is now indexed by line+column instead of by line only. See http://jonasdevlieghere.com/post/lldb-column-breakpoints/ for a high-level introduction to column breakpoints.

@Michael137 Do you know if there is any way I could manually trigger the lldb-aarch64-ubuntu and the MacOS CI before merging this, to get CI feedback before merging this? Also, from what I can tell, all test failures in Buildkite seem to be due to Bolt and unrelated to my PR. Is it safe to merge despite those failures? Or could they hide actual LLDB issues potentially introduced by my commit? |
There's currently no way to trigger the macOS CI unfortunately. Based on the CI |
|
Feels a bit silly that we ran all LLVM/Clang/etc. tests just because you amended the LLVM release notes |
Is a manual trigger possible for the Is another round of "merge, pray, revert" our only option here, or is there anything else I can do to merge this with more confidence? |
Not sure tbh. You can re-run failed runs, but not sure if you can trigger specific test-suites to run. I'd suggest you just merge this since the LLDB linux tests passed |

This commit adds support for column breakpoints to lldb-dap To do so, support for the `breakpointLocations` request was added. To find all available breakpoint positions, we iterate over the line table. The `setBreakpoints` request already forwarded the column correctly to `SBTarget::BreakpointCreateByLocation`. However, `SourceBreakpointMap` did not keep track of multiple breakpoints in the same line. To do so, the `SourceBreakpointMap` is now indexed by line+column instead of by line only. This was previously submitted as llvm#113787, but got reverted due to failures on ARM and macOS. This second attempt has less strict test case expectations. Also, I added a release note.

This commit adds support for column breakpoints to lldb-dap To do so, support for the `breakpointLocations` request was added. To find all available breakpoint positions, we iterate over the line table. The `setBreakpoints` request already forwarded the column correctly to `SBTarget::BreakpointCreateByLocation`. However, `SourceBreakpointMap` did not keep track of multiple breakpoints in the same line. To do so, the `SourceBreakpointMap` is now indexed by line+column instead of by line only. This was previously submitted as llvm#113787, but got reverted due to failures on ARM and macOS. This second attempt has less strict test case expectations. Also, I added a release note.
