[LLVMdev] Profiling - execution count of basic blocks...

Hi gang, time for my weekly confusion... (I'm trying not to bombard the
board with questions)
The thing that's on my mind at the moment (there's some backend-stuff that
I'm just working my way though) is that I'm not getting very far when
trying to get LLVM to profile code - I'm looking for nothing more special
than list of how many times each basic block has been called - but when
wading though the docs I get lots of command line fragments that don't work
and the distint impression that the method for profiling has changed three
times in the last three release - I don't suppose that you have any insight
into what's going on with profiling for llvm...? I'm starting to get the
feeling that I've missed something obvious... My setup is:
LLVM version 3.2svn
DEBUG build with assertions.
Built Jul 27 2012 (18:29:09).
Default target: x86_64-apple-darwin11.4.0
Host CPU: corei7-avx
