--- Comment #3 from Florian Weimer <fw at gcc dot gnu.org> --- (In reply to Uroš Bizjak from comment #1) > Please also use -mincoming-stack-boundary=2 to tell the compiler about > possible incoming stack (mis)alignment. This does change the result; alignment is performed. This is not documented. I'm not sure what the intent is here. (In reply to Uroš Bizjak from comment #2) > FYI, -mstackrealign applies only to main (). I don't think this is true. In the example, stack alignment is performed if I use __m128 instead of __m64.
