--- Comment #101 from Dzianis Kahanovich <mahatma at eu dot by> --- Created attachment 47754 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=47754&action=edit additional aligning on demand 10.0 (unsure) This is same for gcc 10.0 and not fully verifyed. It MUST work in gcc 10.0, but in current git options helps show nothing changed: gcc -Q -O3 -m32 -march=core2 --help=target --help=optimizers |grep 'stackrealign\|cost-model' Looks like deep options behaviour rework in progress.
