<pre>Several Mips and X86 CodeGen tests FAIL on Solaris/sparcv9:
LLVM :: CodeGen/Mips/cconv/vector.ll
LLVM :: CodeGen/Mips/msa/basic_operations.ll
LLVM :: CodeGen/Mips/msa/i5-b.ll
LLVM :: CodeGen/Mips/msa/immediates.ll
LLVM :: CodeGen/X86/fp-intrinsics.ll
LLVM :: CodeGen/X86/known-signbits-vector.ll
LLVM :: CodeGen/X86/vec_shift5.ll
LLVM :: CodeGen/X86/vector-shift-ashr-128.ll
LLVM :: CodeGen/X86/vector-shift-ashr-256.ll
This only happens in 2-stage Release and RelWithDebInfo builds, 2-stage Debug
builds and 1-stage Release builds with gcc are fine.
Sometimes the differences are quite small, e.g. for
CodeGen/Mips/cconv/vector.ll:

In other cases the differences are quite substantial. I have no idea where
even
to start investigating this, so I'll need much guidance here.</pre>
