[LLVMdev] About test suits Cont1

[Eric Christopher]

I'm not quite sure what on earth you're doing.

Let's start from some questions:

a) llvm-gcc-4.2-version-platform.tar.gz

I don't know what this is. Does it contain binaries? I don't see you building llvm-gcc at any point, or installing binaries for it.

b) your commands have a lot of variables in them. Could you perhaps show the actual commands you're running, very simply? It's only about 10 lines.

Comments:

a) If you've got a failing configure then not re-running configure for subdirectories isn't likely to change anything is it?

b) In a grep of my llvm build directory I have:

[yendi:Data/builds/build-llvm] echristo% grep EMITIR *
Makefile.config:LLVMCC_EMITIR_FLAG = -emit-llvm
config.log:LLVMCC_EMITIR_FLAG='-emit-llvm'
config.status:s, at LLVMCC_EMITIR_FLAG@,|#_!!_#|-emit-llvm,g

If you've done your configure correctly you'll see something similar.
