[llvm-commits] [PATCH] PowerPC: More support for Altivec compare operations

[Adhemerval Zanella]

Will,

The llvm_unreachable (...) is a define to llvm_unreachable_internal (lib/Support/ErrorHandling.cpp) 
and it does not accepts a vararg as argument. It means to construct a more elaborate errors message
I'll need to code its construction. And since it is something wrong with the compiler itself and
one will have to attach a debugger to check what it is wrong, I'm not compelling to add these kind 
of logic.
