--- Comment #100 from Dzianis Kahanovich <mahatma at eu dot by> --- Created attachment 47753 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=47753&action=edit additional aligning on demand <10.0 Finally (for me), if somebody think to patch by H.J. Lu is not enough, there are my patch to force "-fvect-cost-model=cheap -fsimd-cost-model=cheap" or "-mstackrealign" on demand. Default - first, as no abi violation, but if defined ENABLE_STACKREALIGN_ABI_VIOLATION=1 - first choice will be "-mstackrealign". This is for gcc <10.0 and verifyed.
