--------------------------------------
Summary: Add support for building the toolchain with Clang
Key: IMPALA-13351
URL: https://issues.apache.org/jira/browse/IMPALA-13351
Project: IMPALA
Issue Type: Epic
Components: Infrastructure
Affects Versions: Impala 4.5.0
Reporter: Joe McDonnell
The toolchain currently builds with GCC 10.4.0. Being able to build with Clang
could be useful:
# More extensive TSAN: TSAN is more effective when dependencies have been
built with TSAN enable. This can help for cases like Boost.
# Comparing Clang performance to GCC: Clang has seen significant development
from Google and others, and it would be nice to know if Clang is faster than
GCC for Impala. Recent versions of Snappy (>=1.1.9) are known to run faster on
Clang than GCC by substantial margins.
# MacOS uses a compiler based on Clang
