All-
I was wondering if anyone knew how I could modify gcc to not use static
general purpose registers on an IA-64 machine? Specifically, I only want
the compiler to allocate registers from the register stack engine (RSE)
and the system defined registers (e.g., stack pointer, global pointer,
etc). I do not want to allocate general purpose registers 2-11 or 14-31.
Any ideas?
Thanks,
Chad Rosier
ps. please reply to my email address as well as the mailing list as I'm

It is better ask such things on gcc-help. You can use -ffixed-REG
option to prevent allocation of such registers or change FIXED_REGISTERS
macro in ia64.h.
