Thanks for working on this. You mentioned

> This patch changes the behavior of decodeBBAddrMap to trace through relocations to get correct function addresses if it is going through a relocatable object file."

How is this achieved? Each BBAddrMap section has a corresponding .rela section, but that .rela section does not contain real address information (the addresses are only known at linker time). (Most of the time) It has entries of <offset_into_bbaddrmap_section, ".text", addend>. Are you computing function addresses as  ".text address as exhibited in the object file + addend"?
