2006-04-27[MIPS] Fix branch emulation for floating-point exceptions.Ralf Baechle
In the branch emulation for floating-point exceptions, __compute_return_epc must determine for bc1f et al which condition code bit to test. This is based on bits <4:2> of the rt field. The switch statement to distinguish bc1f et al needs to use only the two low bits of rt, but the old code tests on the whole rt field. This patch masks off the proper bits.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
