[LLVMdev] Static Profiling Algorithms in LLVM
...a static profiler for LLVM as a google summer of
code project in 2009. I wrote it for the 2.4 branch, but the
implementation never made into the tree. I have recently ported it to
LLVM 2.8, but I haven't tested it. You can take a look at the code
from: http://homepages.dcc.ufmg.br/~rimsa/tools/stprof-llvm.patch
The implementation is based on Wu's [1994] paper and provides a
branch predictor that calculates probabilities. The implementation
also covers an intraprocedural and interprocedural frequency
calculator for edges and functions.

[LLVMdev] About static-profile in llvm-2.8
When I searched for branch frequency profiling on the internet, I got this
link by a casual chance:
http://homepages.dcc.ufmg.br/~rimsa/tools/stprof-llvm.patch.
It seems it was written by Andrei Rimsa.
So I downloaded and integrate these files into the llvm-2.8 building. After
the building, I tried "opt -static-profile bitcnt_1.bc", and an segment
fault error occured. I debugged it step by step, and found the initial
reason was:

[LLVMdev] Static Profiling Algorithms in LLVM
Hi all,
Does LLVM infrastructure contain implementation of any static profiling
algorithm apart from "Spill-Weight" calculation present in Live Intervals
class? The future work page does suggest implementation of some "static
profiling" algorithms to make an educated guesses about the relative
execution frequencies of various parts of the code.
Thanks
