Hi,
I am trying to disable pass arguments by register in my project. I
suppose -mregparm=0 can do this but unfortunately it doesn't work with
-O3. The arguments are still through registers even I specified
-mregparm=0.
I am not sure if this intentional or a bug? -mregparm is a specific
option.
It's a static function. 32bit x86. I tried both gcc4.5.2 and gcc4.7.2,
the behavior is same.

I am actually doing some instrumentation on the binary code generated
by gcc. I did it successfully for class methods and external functions
but failed on the static functions.

Hi,
I am working on huge object files and I am glad to see that gcc
supports -mcmodel=large now. However, my experiment even doesn't work
because of relocation problem in crtbeginS.o
My Source file: t.c
#include stdio.h
extern int foo(int argc, char **argv);
void *pv1[1024]={(void*)foo,};
