Re: Gcov support in Covoar

Hello, I have made the changes and also got the confusion with structure of gcno, cleared to some extent after some careful reading and experiments. I'm attaching the txt file generated. So far it is complete up to function record, next is the basic block records. I will start with the block reco

Re: Gcov support in Covoar

This definitely looks like the right direction. If we don't understand the file formats, we will never be able to process and correlate them. Please put 0x in front of hex numbers. It does help. Can you explain the fields in gcno_dump.txt? The Version field looks like hex for R37A which doesn't m

Re: Gcov support in Covoar

I think that the whole gcov support needs to be reworked. I was looking into how llvm outputs their gcov data in gcda file format here https://github.com/llvm-mirror/compiler-rt/blob/master/lib/profile/GCDAProfiling.c I need some help in understanding the workflow of how covoar gets the trace inpu
