This: + and r2=IA64_SAL_PLATFORM_FEATURE_ITC_DRIFT,r2 ;; + cmp.ne p8, p0=0, r2 +(p8) br.spnt.many fsys_fallback_syscall can be shortened to: tbit.nz p8, p0=IA64_SAL_PLATFORM_FEATURE_ITC_DRIFT_BIT, r2 (p8) br.spnt.many fsys_fallback_syscall Might make it a bit easier to schedule things around (just add foo_BIT numbers for all the SAL_PLATFORM_FEATURE bits and then define the masks in terms of these bit numbers). Sorry I didn't catch this previously. --david
