[LLVMdev] Easiest way to collect dynamic Instruction execution counts?
Hi,
I'd like a simple and fast way to collect the number of times each
Instruction was executed in a given run of the application. As far as I can
tell, there are a number of approaches I can take:
- Use PIN. This would require using DWARF debug info and Instruction debug
info to attempt to map instructions in the binary to instructions in the
bitcode; not 100% sure how accurate this will
