There are MIPS engineers working on LLVM.

Your knowledge is certainly appreciated Chris! 

Happy Thanksgiving, if you celebrate!

I guess the logical follow-on question I'd have is whether any of the MIPS code that's being added to open-source compilers is targeted at our beloved R-series processors...

That I couldn’t tell you, but there’s certainly general MIPS codegen improvement happening, and it’s easy to check the history of individual files or hierarchies to see whether the changes apply to SGI hardware.

A longer term project would be to add MIPSpro 7.4.4 C++ ABI compatibility. The clang C++ ABI handling is sufficiently flexible—mainly to support binary compatibility with the Windows C++ ABI and the existing GNU C++ standard library on some platforms—that this could be done in a way that would allow linking with ViewKit, OpenInventor, IFL, etc. C++ APIs.
