I guess there's something gone wrong with our CI. Previously we decided to ignore changes in *.md files to avoid wasting CI time, but actually, it's running!

LGTM

I guess there's something gone wrong with our CI. Previously we decided to ignore changes in *.md files to avoid wasting CI time, but actually, it's running!

This is the run: https://github.com/python/cpython/actions/runs/9489036340

I don't know why, but it's because the workflow file used for the run doesn't contain the '!**/*.md' exceptions: https://github.com/python/cpython/actions/runs/9489036340/workflow

Which were added in #119147 and are still in main: https://github.com/python/cpython/blob/main/.github/workflows/jit.yml

I've created #120435 to try to fix that.
Actually, what do you mean when you say "but it's because the workflow file used for the run doesn't contain the '!**/*.md' exceptions:"? I'm seeing that:

name: JIT
on:
  pull_request:
    paths:
      - '!**/*.md'
      - '!**/*.ini'
      - '**jit**'
      - 'Python/bytecodes.c'
      - 'Python/optimizer*.c'
      - '!Python/perf_jit_trampoline.c'
  push:
    paths:
      - '!**/*.md'
      - '!**/*.ini'
      - '**jit**'
      - 'Python/bytecodes.c'
      - 'Python/optimizer*.c'
      - '!Python/perf_jit_trampoline.c'

So it does... I missed them because the PR added them to the end of the lists, not the top: 🤔

       - '**jit**'
       - 'Python/bytecodes.c'
       - 'Python/optimizer*.c'
+      - '!Python/perf_jit_trampoline.c'
+      - '!**/*.md'
+      - '!**/*.ini'
   push:
     paths:
       - '**jit**'
       - 'Python/bytecodes.c'
       - 'Python/optimizer*.c'
+      - '!Python/perf_jit_trampoline.c'
+      - '!**/*.md'
+      - '!**/*.ini'

I wonder why they're different.

Is it possible to specify just --version=18, without minor and patch releases? Other tools do not specify exact version.

Unfortunately, no.
We can also omit --version and the latest stable release will be installed. What do you think about that?

[vstinner]

I prefer to stick to a version.

[Eclips4]

So, here's the list of available versions:

llvm 18.1.6 [Approved] Downloads cached for licensed users
llvm 18.1.5 [Approved] Downloads cached for licensed users
llvm 18.1.4 [Approved] Downloads cached for licensed users
llvm 18.1.3 [Approved]
llvm 18.1.2 [Approved]
llvm 18.1.0 [Approved] Downloads cached for licensed users

Which one do you prefer? The latest one?

[vstinner]

Latest, yes.

[Eclips4]

Done

[vstinner]

LGTM.

[sobolevn]

We would have to update it from time to time, but there's no other way, I guess ;)

Thanks!
