[cfe-dev] Error in backend of 3.2

[Jack Poulson]

Dear all,

I'm not sure what information is needed from me to resolve this, but, using:
Debian clang version 3.2-debian1ppa1~exp5 (tags/RELEASE_32/final) (based on
LLVM 3.2)
Target: i386-pc-linux-gnu
Thread model: posix

I received the following backend error:

fatal error: error in backend: Cannot select: 0xb898ff8: i32 = fexp2

after my build system ran the following command:

/usr/bin/clang++-3.2   -Delemental_EXPORTS -O3  -fPIC
-I/home/poulson/Install/include
-I/usr/lib/python2.7/dist-packages/numpy/core/include

CMakeFiles/elemental.dir/src/blas-like/Trr2k.cpp.o -c
/home/poulson/Source/Internal/elemental/src/blas-like/Trr2k.cpp

For what it's worth, this is the relevant file:
https://github.com/poulson/Elemental/blob/master/src/blas-like/Trr2k.cpp

Please let me know if I can provide any more information.
