Does somebody understand what this assertion here enforces? My backend
defines standard register elimination as below.
gcc_assert ((SUPPORTS_STACK_ALIGNMENT
&& (elim == hard_frame_pointer_rtx
|| elim == stack_pointer_rtx))
|| elim == (frame_pointer_needed
? hard_frame_pointer_rtx
: stack_pointer_rtx));
#define ELIMINABLE_REGS \
{ \
{ ARG_POINTER_REGNUM, STACK_POINTER_REGNUM }, \
{ ARG_POINTER_REGNUM, FRAME_POINTER_REGNUM }, \
{ FRAME_POINTER_REGNUM, STACK_POINTER_REGNUM } \
}
Thanks,
Regards,
Hendrik Greving
