[LLVMdev] make check-all failing 18 tests with --enable-optimized

[James Molloy]

Thanks for this, I noticed this recently also (and internally expect it to
fail).

I have now made a report at http://llvm.org/bugs/show_bug.cgi?id=11552.

I don't know about the LLVM errors, but I have seen the Clang error before.
It occurs because the test is not path independent. In
Preprocessor/macro_paste_c_block_comment.c you have 'nog grep scratch',
which means that you can't have 'scratch' in your path. I think this should
be reported as a bug.

I'm not sure what you mean.  I'm getting blocks of "Machine code for
function" for some of the failing tests.  In other cases I'm getting what
looks like a memory dump.  I have the output from the latest run at the
following URL if that helps:
