I tested on the current master: git clean -fdx ./configure --with-lto --enable-optimizations sed -i -e 's/^PROFILE_TASK=.*/PROFILE_TASK=-c pass/' Makefile make 2>&1|tee log Python is compiled twice: * (1) gcc -DNDEBUG -g -O3 -flto -fprofile-generate (...) * (2) gcc -DNDEBUG -g -O3 -flto -fprofile-use (...) I see -g in both compilation steps. It seems like debug symbols are still here: vstinner@apu$ file ./python ./python: ELF 64-bit LSB executable, x86-64, (...), with debug_info, not stripped But I confirm that test_gdb fails when using LTO+PGO. gdb seems to be to read any C function argument: $ gdb -args ./python Lib/test/gdb_sample.py (gdb) b builtin_id (gdb) run Breakpoint 1, 0x0000000000518da0 in builtin_id () (gdb) py-bt Traceback (most recent call first): (unable to read python frame information) (unable to read python frame information) (unable to read python frame information) (unable to read python frame information) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue30345> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
