llvm-mirror/unittests/ADT/TripleTest.cpp
Chandler Carruth c5b687b241 Support was removed from LLVM's MIPS backend for the PSP variant of that 
chip in r139383, and the PSP components of the triple are really
annoying to parse. Let's leave this chapter behind. There is no reason
to expect LLVM to see a PSP-related triple these days, and so no
reasonable motivation to support them.

It might be reasonable to prune a few of the older MIPS triple forms in
general, but as those at least cause no burden on parsing (they aren't
both a chip and an OS!), I'm happy to leave them in for now.
