Hi, I am using Path Profiling to path profile a C code. I'm using this commands: $ llvm-gcc -c -emit-llvm file.c -o file.bc $ opt --insert-hotpath-profiling file.bc -o file.ins.bc $ llc -march=x86 file.ins.bc -o file.ins.s $ gcc -I llvm2.9/runtime/PathProfling.c -I llvm2.9/runtime/CommonProfiling.c $ ./a.out This will give me path profile of of program in 'llvmpro.out' to decode

Hi Andreas, First, thanks again for undertaking this work and submitting it back. There is a lot of good stuff here and it would be great to see it get back into the tree. I have a few major high-level comments on the patch. First off, the patch is quite large and should be broken down into separate incremental changes which are easier to review and apply. I think the patches should more or less

Hi all, as proposed in http://lists.cs.uiuc.edu/pipermail/llvmdev/2009-February/020396.html I implemented the algorithm presented in [Ball94]. It only instruments the minimal number of edges necessary for edge profiling. The main changes introduced by this patch are: *) a interface compatible rewrite of ProfileInfo *) a cleanup of ProfileInfoLoader (some functionality in ProfileInfoLoader

...h providing a ProfileInfo > level API to query whether any information is present for a particular function > so that clients don't perform needless queries. I have to look into this one, I guess its possible to do this kind of check on demand and calculate BlockCounts from EdgeCounts and FunctionCounts form BlockCounts when necessary. >> --- llvm-van/lib/Analysis/MaximumSpanningTree.cpp 1970-01-01 01:00:00.000000000 +0100 >> +++ llvm-c7/lib/Analysis/MaximumSpanningTree.cpp 2009-06-26 16:47:01.000000000 +0200 > ... >> +#define WOOD_REP(M,V1,V2) \ > > Please us...
