Frank Ch. Eigler ebcfd86a2e * 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.

Sun Apr  5 12:05:44 1998  Frank Ch. Eigler  <fche@cygnus.com>

	* 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.
