count in spill_regs

Subject: count in spill_regs

Hi,

I am interested to know if there is any option that would tell me how many
registers have spilled. I noticed that there is spilled_regs array in
reload1.c - but I can't seem to find where it dumps that information.
Potentially I could build compiler with debug information; however, if an
option exists, that would be great.

If anyone knows of such an option, please share.

Thanks.
Sirish
