[LLVMdev] [PATCH] & Question: Preserving ProfileInfo for backend.

Hi,

the second part of my work is to preserve the profiling information
through all the transformation passes and make it available to the
backend machinery.

Attached is an example patch on how I plan to preserve the information
for a given transformation pass.

And now comes the question into place: whats the best way to attach the
profile info also the MachineBlocks and MachineFunctions? I was thinking
of converting the ProfileInfo into a template and using it for both
BasicBlocks and MachineBasicBlocks.

And where is the best point to transfer this information from the
bytecode CFG to the machinecode CFG?

Thanks, Andi
