llvm dev - Jul 2009 - [LLVMdev] Unexpected failures in the DejaGNU test collection

Hi all,

When using "make check" with the DejaGNU test collection, I encounter
two unexpected failures (they seem to be closely related).
My question: are they well known, and if so what's the problem and how
can I fix it?

This is the error text I get:

Hello Harel,

Failures in the FrontendC test suite usually means that your llvm-gcc  
is older than your LLVM tree.

Try compiling llvm-gcc from top-of-tree and see if the failures remain.

Since it came up, what is blocking us from putting these tests in the
llvm-gcc test suite instead of in the LLVM test suite?

Hi Jakob,

We're using unmodified release version 2.5 of both llvm and
llvm-gcc-4.2 and that same problem I mentioned shows up in both the
DejaGNU tests and in the test-suite, and I even checked on two
different boxes. Everything else works perfectly.

Nobody encountered those failures?
