Ralf, Here is a bunch of instruction emulation fixes and clean-ups, mostly though not only affecting branches in the FPU emulator. The severity of failures addressed varies, see the individual patch descriptions for details. These patches have been verified to a varying extent, depending on the nature of the individual change, by running the GCC and glibc test suites for the MIPS16 o32 little-endian multilib. NB I don't know why `checkpatch.pl' complains about the correctly line-wrapped commit references with some of these patches. Please queue for the next release cycle and backport as noted with each of the patches. NB there is also an API mismatch between `init_fpu' returning SIGFPE and its caller `__compute_return_epc_for_insn', however I can't figure out why the incorrect return status is only passed up if NO_R6EMU, so I'm leaving it to whoever understands the dependency here to fix up. Offhand it looks to me like the whole containing `!used_math()' conditional is bogus though -- we've got an exception in a delay slot of a COP1 branch, so the FPU clearly must have been used already or we wouldn't have reached the delay slot to trap in in the first place. For the same reason we do not need to check `cpu_has_mips_r6' other than for telling overlapping R6 BC1EQZ and MIPS-3D BC1ANY2 minor opcodes apart, which we don't do anyway. So more fixes and clean-ups are due around here it would seem. But this is too much for the amount of time I can afford right now, so I'll be leaving them for the next opportunity. Maciej
