[LLVMdev] Introduction to the Profiling Infrastructure

[Slobodan Pejic]

Dear LLVM Developers:

I am an undergraduate summer research student supervised by José Nelson 
Amaral at the University of Alberta.

My work will primarily involve value profiling and path profiling.  
Andreas Neustifter is planning some changes to the profiling related 
code in LLVM 
(http://lists.cs.uiuc.edu/pipermail/llvmdev/2009-February/020396.html).  
Are any of these changes in yet?  Which transforms that use profiling 
information should I pay attention in order to learn the code related to 
profiling?  Based on the overview of analyses and transformations, 
profile guided basic block placement 
(http://llvm.org/docs/Passes.html#block-placement) seems to be my best bet.
