- Subject: Branch prediction
Is there any documentation for what gcc does with branch prediction
information it gets from profiling? I am interested in this for
modern Pentium processors where you can no longer give hints.
Specifically I am interested in whether there are in fact any
optimisations that work reliably from this information.
