Update to LLVM 22 #150722

nikic · 2026-01-06T11:26:00Z

Scheduled release date: Feb 24
1.94 becomes stable: Mar 5

Changes:

Update to rc2, with one patch to work around our outdated illumos sysroot (rust-lang/llvm-project@41256ab).
Update the host toolchain as well, otherwise we lose cross-language LTO, in particular for jemalloc.
Adjust one loongarch assembly test. The split into r and s variants is based on the suggestion in tests: fix loongarch test for new LLVM 23 codegen #151134.

Overall result: ❌✅ regressions and improvements - please read the text below

Benchmarking this pull request means it may be perf-sensitive – we'll automatically label it not fit for rolling up. You can override this, but we strongly advise not to, due to possible changes in compiler perf.

Next Steps: If you can justify the regressions found in this try perf run, please do so in sufficient writing along with @rustbot label: +perf-regression-triaged. If not, please fix the regressions and do another perf run. If its results are neutral or positive, the label will be automatically removed.

Based on helloworld, the perf regressions seem to be related to the allocator somehow. Previously tcache_alloc_small_hard was called 3 times, now it's called 189 times. The total number of allocations is smaller, but the time spent in the allocator is larger.

nikic · 2026-01-08T14:29:53Z

Or maybe the issue is not actually the allocator behavior itself. I suspect that we might have lost LTO on jemalloc and tcache_alloc_small_hard previously got inlined into malloc_default but now no longer is. Possibly updating the host toolchain at the same time so that the versions match will help.

Looks like this is causing some segfaults in LoopDeletionPass - #151790.

nnethercote · 2026-01-28T23:03:25Z

About the perf results: the icount results look great, but LLVM updates are big enough that looking at the cycle counts and wall-times is reasonable -- more so than typical PRs that make very small changes. In this case the cycle count and wall-time results are a little bit in the red. We saw a similar thing with the LLVM 21 update. This is different to the previous few LLVM updates before 21 where we saw uniform improvements across icounts/cycles/wall-time.

I'm not sure what to make of this, and it's not going to stop us from updating to LLVM 22. But it seems worth mentioning.

Should this comment be updated? That script is on LLVM 20 and the update cadence seems to be intentionally different.

Yes, we should drop this comment, people are regularly confused by it.

Well we should still try to keep those two close :)
