[LLVMdev] Path profiling command
Hi members,
I am a LLVM newbee. I am working in path profiling. I got an error message when
reading the path profile data
I made a sample source named foo.c
The command chain to make llvm path profiling as follows:
1. Compile to LLVM Bitcode
llvm-gcc –emit-llvm foo.c –c –o foo.bc
2. Insert Path Instruments
opt –insert-path-profiling foo.bc –o foo_path.bc
3. Link with profile
