Profiling information

How do I find the profiling or run time information for machine basic
blocks from a machine function? There are quite a few optimization
that may be preformed with this information, when it exists.

Thanks,

Bump:

Does profiling / run time information exist when dealing with machine
basic blocks?

Thanks,

Most of the profiling infrastructure was removed a while ago due to
bit-rot and lack of interest. (What did exist was at the LLVM BB
level, not machine BB, but it shouldn't be too hard to forward the
useful information).
