commit ce8bc71ff7e0cfc0c39511308df8841f39fb03d2
Author: Joe McDonnell <[email protected]>
Date: Tue Mar 12 21:47:12 2024 -0700 IMPALA-12900: Build binutils with -O3
The binutils build happens before we have switched over to
using the toolchain compiler. This means that it also does
not set CFLAGS/CXXFLAGS. The default optimization level
for binutils is -O2. It is possible that we could get a bit
extra speed by using -O3, so this sets CFLAGS/CXXFLAGS to use
-O3 for binutils.
Testing:
- Toolchain builds on x86_64 and ARM

> Affects Versions: Impala 4.3.0
> Reporter: Joe McDonnell
> Assignee: Joe McDonnell
> Priority: Major
>
> Since the toolchain builds binutils with the native compiler (as the
> toolchain compiler hasn't been built yet), we haven't set CFLAGS yet. The
> default CFLAGS for binutils use -O2. It's possible that we could get a bit
> more speed by building with -O3. We should set CFLAGS/CXXFLAGS to use -O3.
