* R5900 COP2 function nearly complete. PKE sim now aware of new GPUIF
masking facility for PATH3 transfers.
[ChangeLog.sky]
Sun Apr 5 12:11:45 1998 Frank Ch. Eigler <fche@cygnus.com>
* sky-libvpe.c (exec-inst): Added "M" bit detection for upper
instruction.
* sky-pke.c (pke_check_stall): Added more assertions.
(pke_code_mskpath3): Use new GPUIF M3P control register.
* sky-pke.h (VU[01]_CIA): New macros that give VU CIA
pseudo-register addresses.
* sky-vu.h (vu_device, VectorUnitState): Merged structs.
(VectorUnitState.mflag): New field.
(VU_REG_{CMSAR0,CMSAR1,FBRST}) Added missing control registers.
* sky-vu.c (vu0_busy): New function.
(vu0_q_busy): New function.
(vu0_macro_issue): New function.
(vu0_micro_interlock_released): New function.
(vu0_busy_in_{micro,macro}_mode): Deleted stubs.
(vu0_macro_hazard_check): Deleted stubs.
(vu_attach): Adapted code to merged device & state struct.
(read_vu_special_reg): Compute VBS0/VBS1 bits in STAT register.

* interp.c (*): Adapt code to merged VU device & state structs.
(decode_coproc): Execute COP2 each macroinstruction without
pipelining, by stepping VU to completion state. Adapted to
read_vu_*_reg style of register access.
* mips.igen ([SL]QC2): Removed these COP2 instructions.
* r5900.igen ([SL]QC2): Transplanted these COP2 instructions here.
* sim-main.h (cop_[ls]q): Enclosed in TARGET_SKY guards.
