I repeated the same tests for Python 3.7 on PR 11264.
I replaced "38" with "37" and "3.8" and 3.7" and my 3 scripts :-) I modified step1.sh for PGO+LTO with -O0:
set -x -e
git clean -fdx
./configure CC=clang --with-lto --prefix /opt/py37 --enable-optimizations
sed -i -e 's/^PROFILE_TASK=.*/PROFILE_TASK=-c pass/' Makefile
sed -i -e 's/-O3/-O0/' Makefile
make 2>&1|tee log
grep -E -- '-o python|-o Python/bltinmodule.o|Modules/_asynciomodule.o' log|grep -c lto
# 4 expected: -flto passed to compiler *and* linker
Test results:
./configure CC=clang --with-lto --prefix /opt/py38
(1) 4
(2) 0, False => OK!
(3) 0 => OK!
./configure CC=clang --with-lto --enable-shared
(1) 4
(2) 0, False => OK!
(3) 0 => OK!
./configure CC=clang --with-lto --enable-optimizations
(1) 8 => OK!
(2) 0, False => OK!
(3) 0 => OK! |
