During building you may encounter lots of coredumps, slowing build down or even dramatically reducing the responsiveness of your system.

See https://wiki.archlinux.org/title/Core_dump for solutions/workarounds .

Archlinux currently has 3 llvm git implementations

  1. this package

    • see other pinned comments for details

  2. llvm-git

    • It aims to provide a full llvm/clang compiler environment for development purposes.
    • Supports cross-compiling , bindings for external stuff (python, ocaml etc) , and some things not in extra-llvm.
    • intended to be used with archlinux core,extra & community repos
    • CONFLICTS with extra llvm/clang packages
    • binary versions in chaotic aur unofficial repository

  3. packages created & maintained by Lordheavy, an arch developer

    • intended to be used with archlinux testing repos
    • sometimes has problems on systems where testing repos are disabled
    • uses same package structure as llvm/clang in official repos
    • source
    • binary versions in LordHeavys unoffical repo

Why does this package exist ?

Llvm & aur llvm-git are intended to provide a full development environment of llvm/clang suite that can replace eachother completely (aur llvm-git adds some xtra functionality)

llvm-minimal-git is a stripped-down llvm trunk build with these goals :

  • llvm-libs-minimal-git must coexist with stable llvm-libs
  • provide what's needed for mesa trunk (it's a hard dependency for mesa-minimal-git and a possible dependeny for mesa-git)
  • provide basic llvm/clang compiler functionality on x86-64 architecture

Some of the things that are stripped out :

  • cross-compiling support
  • bindings for ocaml
  • bindings for go
  • lld , lldb and polly
  • documentation
  • examples
  • benchmarks

Maintainers (and users) should only depend on llvm-miminal-git after verifying it satisfies what they need.

When building this you are likely to see test failures in terminal output / logs.

The command used for the tests has been changed to continue regardless of failures. Incase you don't want to run the tests you can use --nocheck option of makepkg.

Unfortunately, the patches need some work again. Various release notes diffs fail, one test and this one in Patch 3: 1 out of 4 hunks FAILED -- saving rejects to file llvm/include/llvm/LinkAllPasses.h.rej

This is the one we need to revert as 0008 :

[PassManagerBuilder] Remove PassManagerBuilder

blackmoon3, I had to add 3 more reverts just to get the original revert working again.

I've tried to add a revert for the commit you mentioned but it can't be reverted cleanly . increassing fuzz doesn't help, I think more commits need to be reverted to keep that function for clover working .

This is what I get when adding a revert for that commit between 0002 and 0001 .

Hi you should also revert this commit : https://github.com/llvm/llvm-project/commit/15977742d3ebba05a33a8eac3201ebba9c9f10e3

This allow mesa-git package to build with gallium-opencl=icd

Because mesa use this function : https://gitlab.freedesktop.org/mesa/mesa/-/blob/main/src/gallium/frontends/clover/llvm/invocation.cpp#L461 that have been removed by upstream llvm

I tested the revert patch in my own llvm-minimal git repo and just compiled llvm and mesa with no problem. https://github.com/blacksky3/llvm-minimal-git.git

I just added : patch --directory="llvm-project" --reverse --fuzz=50 --strip=1 --input="${srcdir}/0001-Reland-LegacyPM-Remove-some-legacy-passes.patch" in the prepare function to let the path fully apply with no problem

This revert patch can also be applied in lib32-llvm-minimal-git for the same reasons

Reported the issue to mesa repo : https://gitlab.freedesktop.org/mesa/mesa/-/issues/8591

Thanks, will look into adding those 2 patches (and verify if that's enough for some time) this weekend.

Just tried to build llvm-minimal-git tonight and it failed when trying to apply the patches.

Reverted those 2 commits and building works again :

[llvm-c] Remove bindings for creating legacy passes

[IPO] Remove various legacy passes

Lone_Wolf commented on 2022-11-16 21:30 (UTC)

Added new split package spirv-llvm-translator-minimal-git as it is needed for mesa rusticl

libffi was updated, all who use llvm-mimimasl-git need to rebuild it.

Lone_Wolf commented on 2021-10-11 08:33 (UTC)

confirmed, see https://gitlab.freedesktop.org/mesa/mesa/-/issues/5471

Mesa-git will need to be pacthed.
