<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I'd also like to propose the inclusion of the recent ABI fixes to the Mips target but I'm not sure this is a good idea. I'm having difficulty sorting out the dependencies for these at the moment since they seem to depend on some of Eric
Christopher's Subtarget/TargetMachine refactoring. It may also be a bit large for a stable release since it's ~50 LLVM patches and ~8 Clang patches and refactors a large amount of the Mips calling convention code. What do you think?<u></u><u></u></p>
