llvm dev - Feb 2009 - [LLVMdev] problems running test suite (-mllvm -disable-llvm-optzns)

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

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.

That's correct. The driver changes the order of the options provided.
You need to provided this option to cc1 / cc1plus directly
> Is it just me having this problem?
No.

No idea, but I guess you can either hack on gcc specs. Or don't use
this option at all - this is intended only for internal debugging
purposes, so I doubt anyone will be really interested in fixing this.

Dan fixed this recently in svn IIRC - I don't think it's in the
prerelease candidate.

Yes :)

Thanks. I switched to using the testsuite from the prerelease
candidate and I've got it working now.

For the record, there was another problem that frustrated me: the
testsuite couldn't find cc1plus, because when I configured llvm I
hadn't specified --with-llvmgccdir, so llvm's Makefile.config didn't
define LLVMGCCLIBEXEC. But when I configured the testsuite I *had*
specified --with-llvmgccdir, so it had all the information it needed
to find llvm-gcc.

Thanks,
Jay.
