Jin Shang updated ARROW-17902:
------------------------------
Description:
Package managers have been upgrading their default LLVM version to 15. This
raises several compatibility and performance issues for CI, and we currently
are using workaounds
# Mac's default clang 13's LTO cannot read Brew installed llvm static libs
because they are compiled with llvm 15
([https://github.com/apache/arrow/pull/14187#issuecomment-1253322948]).
Workaround: Use brew installed clang: ARROW-17805 ARROW-17842
# Conda's packaging of LLVM 15 on Windows is not portable. It required a
VS2019 Enterprise version:
[https://github.com/conda-forge/llvmdev-feedstock/issues/175.] Workaround: Pin
LLVM to 14 for Conda with Windows. ARROW-17830
# Brew's LLVM15 enables z3 by default and it's shared linked. It breaks Java
jar builds on MacOS:
[https://github.com/apache/arrow/pull/14261#issuecomment-1263024112.]
Workaround: Pin LLVM to 14 for all MacOS tasks.
# LLVM 15 is noticably slower to build than LLVM 14 for brew and MacOS.
Workaround: Pin LLVM to 14 for all MacOS tasks.
We need to find a way to resolve these workarounds for LLVM 15
