11c47f314b * R5900 sky COP2 testing continuing. Today only small
VCALLMS-related were found/fixed.

[ChangeLog.sky]

	* sky-vu.c ({read,write}_vu_special_reg): Add CMSAR[01] as special
 	registers for a VU.  Behavior not as mandated.
	({read,write}_vu_{misc,special}_reg): Create sim_io_error upon
	access to unknown register.  Behavior not as mandated.

	* sky-vu.h (anonymous register numbering enum): Add CMSAR[01].

	* sky-libvpe.c (indebug): Cache $ENV{'SKY_DEBUG'}.

[ChangeLog]


	* Makefile.in (SIM_SKY_OBJS): Added sky-vudis.o.

	* interp.c (decode_coproc): Refer to VU CIA as a "special"
	register, not as a "misc" register.  Aha.  Add activity
	assertions after VCALLMS* instructions.

15232df4a3 * Inserted skeleton of R5900 COP2 simulation. Merged old vu[01].[ch] code
into single PKE-style vu.[ch].


[ChangeLog]

Fri Mar 27 16:19:29 1998  Frank Ch. Eigler  <fche@cygnus.com>

start-sanitize-sky
	* Makefile.in (SIM_SKY_OBJS): Replaced sky-vu[01].o with sky-vu.o.

	* interp.c (sim_{load,store}_register): Use new vu[01]_device
 	static to access VU registers.
	(decode_coproc): Added skeleton of sky COP2 (VU) instruction
 	decoding.  Work in progress.

	* mips.igen (LDCzz, SDCzz): Removed *5900 case for this
 	overlapping/redundant bit pattern.
	(LQC2, SQC2): Added *5900 COP2 instruction skeleta.  Work in
	progress.

	* sim-main.h (status_CU[012]): Added COP[n]-enabled flags for
 	status register.

end-sanitize-sky

	* interp.c (cop_lq, cop_sq): New functions for future 128-bit
 	access to coprocessor registers.

	* sim-main.h (COP_LQ, COP_SQ): New macro front-ends for above.

[ChangeLog.sky]

	* sky-engine.c (engine_run): Adapted from vu[01] -> vu merge.

	* sky-hardware.c (register_devices): Ditto

	* sky-pke.c (pke_fifo_*): Made these functions private again, now
 	that the GPUIF code does not use them.

	* sky-pke.h (pke_fifo_*): Removed newly private declarations.

	* sky-vu.c (*): Major rework: merge of old sky-vu0.c and
 	sky-vu1.c.  Management of two VU devices parallels two PKEs.
	Work in progress.

	* sky-vu.h (*): Other half of merge.
	(vu_device): New struct, parallel to pke_device.

37379a256b IGEN - Replace IMEM (IMEM_IMMED) macro with IMEM<insn-size> macro,
update v850, tic80 and mips simulators.
IGEN - Prepend prefix to more generated symbols and macros
(idecode_issue, instruction_word).
IGEN - Add -Wnowith option to supress warnings about word size
inflicts in input files.
MIPS - Clean up Makefile.in, m16.igen, m16.dc (new), m16run.c (new) so
that a mips16 simulator built using IGEN can be compiled.

7ce8b9178c IGEN likes to cache the current instruction address (CIA). Change the
MIPS simulator so that correctly writes the value of CIA back int PC
(the global previously used) when the simulation halts.
Fix implementation of DELAY_SLOT and NULLIFY_NEXT_INSTRUCTION macros.
