Hi,
What one must use in custom backend to suppress frame pointer usage by default?
Frame pointer is mentioned in ELIMINABLE_REGS:
#define ELIMINABLE_REGS \
{ \
{ARG_POINTER_REGNUM, STACK_POINTER_REGNUM}, \
{ARG_POINTER_REGNUM, FRAME_POINTER_REGNUM
omit the frame pointer for the concerned function.

Hello Everyone,
I have a question regarding using frame pointers. I have a scenario
where I need to use the frame for certain functions and for the other functions
it can optimize it out. I see there is a flag called
"-fno-omit-frame-pointer", which will keep the frame pointer for all t
