[LLVMdev] Profiling - basic block execution frequencies

[David Blaikie]

I've read some small amounts of documentation including the Doxygen
docs on the LLVM Profiling capabilities. I'm looking to extract basic
block execution frequencies (I just need relative values within a
function) in to a simplified custom format for my work (research in to
instruction selection). The API seems geared more towards the use of
profiling data in LLVM Passes and I was wondering if anyone could just
give me a brief overview or point me in the direction of the right
part of the docs on how to easily generate profiling data and use C++
to interact with it and get what I need.

Thanks for your time and a great tool,
David Blaikie
