When I'm using all LLVM fixes I've ever submitted and my SSA patches on top
available at:
    git://github.com/lucvoo/sparse.git sssa-next

This simplifybug.c doesn't seem to have problems with sparse-LLVM.
I'm less sure about the generated code, of course.

This 8000 lines file has a lot of header file dependencies, I'm willing to
take a look at the preprocessed output if you send it.

Only half of the function is there. Care to send to full version?

A floating-point test program while sparse has very very poor
fp support ... hmmm and with a header file dependencies.
Care to send the preprocessed output?
