...he mainline llvm, and I ported it back to 2.7. The same error happened for both of them: the modified 2.7, and a mainline I checked out three weeks ago. This problem is reproducible while compiling flex-2.5.35.tar.gz and many others (mysql and cherokee). I set the following: export PATH="$LLVMPREFIX/bin:$LLVMGCCPREFIX/bin:$PATH" export CC="llvm-gcc -use-gold-plugin -Wl,-plugin-opt=also-emit-llvm" export CXX="llvm-g++ -use-gold-plugin -Wl,-plugin-opt=also-emit-llvm" export RANLIB=/bin/true export CFLAGS="-O4 -g" then configure, make, and then hit the error....

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

Hi there, I checked out the latest code from the repository, and wanna use the gold plugin, but I got the following: libLLVMgold.so: could not load plugin library Do you know why this is happening? Also I noticed the name of the library is changed to LLVMgold.so, and I just renamed it to libLLVMgold.so when I copied it. Is this the right thing to do? Thanks, Guoliang
