[LLVMdev] running spec2006 with clang

[Murali, Sriram]

There were build failures on some spec2006 benchmarks with clang. In order to build 400.perlbench, we added -std=gnu89 option.
464.h264ref needed the flag -fsigned-char set, whereas 456.hmmer needed -funsigned-char.

-std=gnu89 is not valid for c++

I think the point here is that this is the default std for GCC but not Clang, so you have to force clang to behave like GCC. For C++, you'll have to force whatever default GCC has for it's C++ standard.
right,  but what option in clang++ forces it close to g++ for running spec2006 ?

for clang it is apparent -std=gnu89

i understand that we have it configured already for test-suite but I also need to be able to run this standalone (outside of test-suite).



Though, GCC 4.8 is getting very close to Clang's behaviour, so those issues are bound to disappear in the near future.
