* 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.
