Hi, I would like to get the whole program bitcode with debug information in it. I tried to use CFLAGS = "-O4 -g", but it ends with the following error: collect2: ld terminated with signal 6 [Aborted] Unknown constant! UNREACHABLE executed at /local.toadette/aliang/fixing/llvm-2.7/llvm-2.7/lib/Bitcode/Writer/BitcodeWriter.cpp:895! What is the right way to get a whole program bitcode with debug information using gold plugin? Thanks, Guoliang
