Charalampos Stratakis added the comment: Also this is due to an expected behaviour from gcc. From the documentation: "If you use multiple -O options, with or without level numbers, the last such option is the one that is effective. " -- ___

[issue37631] EXTRA_CFLAGS get overrided by CFLAGS_NODIST

Charalampos Stratakis added the comment: Dug a bit further here. The issue is that CFLAGS_NODIST will always come after normal CFLAGS (which are subsets of PY_CFLAGS and PY_CFLAGS_NODIST) [0][1]. The EXTRA_CFLAGS variable is appended at the end of PY_CFLAGS [2], hence as reported here,

Charalampos Stratakis added the comment: I agree that documenting the flags is quite important, I've had a hard time trying to figure out how to implement the LDFLAGS_NODIST, and the change still broke macos builds (luckily it was fixed swiftly). Nevertheless, this is still a bug which

Marcel Plch added the comment: I believe you mean this downstream issue: https://bugzilla.redhat.com/show_bug.cgi?id=1712977 That issue is but only a consequence of a bad flag handling. The bad flag handling affects not only test_gdb on that specific architecture, but the entire

[issue37631] EXTRA_CFLAGS get overrided by CFLAGS_NODIST

New submission from Marcel Plch : Problem: If you want to override CFLAGS by setting EXTRA_CFLAGS, they may have no effect if there are contrary flags in the CFLAGS_NODIST variable. How to reproduce: make CFLAGS_NODIST="-O2" EXTRA_CFLAGS="-Og" If you look at GCC arguments, there is -O2
