llvm dev - Mar 2012 - [LLVMdev] installing llvm from source, make check-all fails on llvm::transforms and clang:preprocessor

I downloaded via svn the release_30 and current version code. I am on  x86_64
GNU/Linux, I am compiling with gcc 4.4.6

I compiled release_30 with

 make ENABLE_OPTIMIZED=0 OPTIMIZE_OPTION=-O0


and current release with

make

In both cases, when I

 make check-all

I get :

Hi Simona, these failures are due to the name of the path to LLVM/clang, see
below.

This test checks that the word "scratch" doesn't occur in the
clang output.
But because it lives under your "/scratch" directory, the word scratch
does
occur, in the path.

Here it is checked that the word "load" does not occur.  But because
it lives
under "download" which contains "load", the word load is
wrongly thought to
occur.

Yes, this is all very silly and shows a weakness in the testing infrastructure.

Ciao, Duncan.

I'm pretty sure this one was fixed after 3.0 branched.
