Hi,


I am doing a project to study gcc spill code on spec2000.
I want to decide the total number of memory loads and stores
due to spill. My question is: given the assembly code generated
by gcc, is there a way to identify instructions for doing
register spilling (in register allocation). I don't know much
about the internals of gcc, in particular, the register allocation.
So it would be nice to find those spill code by checking the
asm .s file only. I am using the MIPS platform, but any suggestions
are appreciated.


Thanks a lot for help.
