The preferred_alignment is 16, but the stack_alignment_needed is just 4. The preferred_alignment is by default for all x86/x64 targets always PREFERRED_STACK_BOUNDARY_DEFAULT (means 128 bit=16 bytes). So crtl->stack_alignment_needed is 32, and crtl->preferred_stack_boundary is 128. A work-a-round is to use -mpreferred-stack-boundary=2 option. This prevents that check fails. So question is: Where stack_alignment_needed is set to something less then preferred_stack_boundary ^ permalink raw reply [flat|nested] 4+ messages in thread
