InstrProf backward compatibility
Hi all,
I am working on adding PGO to LDC (LLVM D Compiler). The current
implementation
1) uses LLVM's InstrProf pass to generate an instrumented executable
2) links to compiler-rt/lib/profile for the runtime functionality to write
a raw profile data file
3) uses llvm-profdata to merge profile data and convert from profraw to
profdata format
4) uses llvm::IndexedInstrProfReader to read-in
