7dd4a46650 * Oops, added #ifdef TARGET_SKY around R5900 COP2 implementation skeleton. 1998-03-29 22:53:31 +00:00
Frank Ch. Eigler
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.

9b23b76d68 * Added --with-sim-gpu2=<path> option for linking SCEI's GPU2 library with
the stand-alone executable.


[in ChangeLog.sky:]

	* sky-gpuif.c (call_gs): Call properly into GPU2 library if
 	configured --with-sim-gpu2.  Use SKY_GPU2_REFRESH symbol as
 	placeholder for future GPU2-refresh policy.

 	configurable settings for stand-alone simulator.

start-sanitize-sky
	* configure.in: Added --with-sim-gpu2 option to specify path of

	* interp.c (MEM_SIZE): Increased default sky memory size to 16MB.
end-sanitize-sky

	* configure.in: Added X11 search, just in case.
