Subject: [linux-ia64] Predication vs. Branching
Date: Tue, 19 Sep 2000 11:45:21 +0000	[thread overview]
Message-ID: <marc-linux-ia64-105590678205502@msgid-missing> (raw)

Hi,

This might not be the appropriate forum, but what the heck. Does anyone
have
a definitive answer on what happens to predicated instructions that are
not
executed (ie where in the pipeline are they discarded). The reason I ask

this is because i am curious about the threshold where it becomes better

to branch around a section of code rather than predicate it.

Best Regards,
Jonathan Nicklin
