src/sys/arch/powerpc/fpu: fpu_emu.c
Log Message:
Try to fix FPSCR bits in the end of emulation:
- FPSCR[FEX] is not a sticky bit.
- Turn on FPSCR[FEX] if the emulated instruction causes invalid operation,
and invalid operation exception is not masked out.
- FPSCR[VX] is not a sticky bit, however it should be set when at least
one of FPSCR[VXfoo] bits (they are sticky!) is set.
- FPSCR[FX] is a sticky bit, and it should be set if FPSCR is modified by
instructions other than mtfsf{,i}.
