[LLVMdev] problems running test suite (-mllvm -disable-llvm-optzns)

[Jay Foad]

I'm trying to run some of the test suite using the instructions here:

http://llvm.org/docs/TestingGuide.html#quicktestsuite

I've built llvm myself, but I'm using pre-built binaries of llvm-gcc
(from http://llvm.org/prereleases/2.5/llvm-gcc4.2-2.5-x86-linux-RHEL4.tar.gz).

Here's what happens:

foad at debian:~/svn/llvm-project/test-suite/trunk$ ./configure
--with-llvmgccdir=/home/foad/llvm/llvm-gcc4.2-2.5-x86-linux-RHEL4
--with-llvmobj=/home/foad/llvm/objdir-svn
--with-llvmsrc=/home/foad/svn/llvm-project/llvm/trunk
[...]

I guess this is because the test suite is trying to run "llvm-gcc
-mllvm -disable-llvm-optzns", which never seems to work, because
llvm-gcc mangles the command line before it gets to cc1plus.

Is it just me having this problem?

How can I fix it?

Thanks,
Jay.
