Hi,
I'm trying to build libpfm-3.2-060512 for my Pentium M laptop and see
pfmlib_gen_ia32.c: In function 'pfm_gen_ia32_detect':
pfmlib_gen_ia32.c:117: error: PIC register 'ebx' clobbered in 'asm'
pfmlib_gen_ia32.c:122: error: PIC register 'ebx' clobbered in 'asm'
pfmlib_gen_ia32.c:117: error: PIC register 'ebx' clobbered in 'asm'
pfmlib_gen_ia32.c:122: error: PIC register 'ebx' clobbered in 'asm'
I think it's just a typo, since you're saving and restoring ebx it
doesn't need to be listed as clobbered?
