[patch][rfc] sh64: Add Pipeline Modelling and SID Support

2006-08-22  Dave Brolley  <[email protected]>

	* Contribute the following changes which add sid support as well as
	pipeline modeling for all sh machines (used by sid). In addition, some
	previously unsupported insns are now supported by both sim and sid.

	2006-07-11  Dave Brolley  <[email protected]>

	* cpu/sh64-compact.cpu (movual, movual2): New insns.
	(movcol): New insn.
	* cpu/sh.cpu (sh4a-nofpu-models): New pmacro.
	* sid.scm (-op-gen-delayed-set-maybe-trace): If delay used, note the
	hardware or memory mode which was used.
	* sid-cpu.scm (hw-need-write-stack?): New function.
	(-gen-hw-stream-and-destream-fns): Compute stack-regs. Use it to
	identify hardware which uses write stacks.
	(useful-mode-names): Renamed to write-stack-memory-mode-names.
	Initialized to an empty list.
	(-gen-writestacks, -gen-reset-fn, -gen-unified-write-fn): Use
	hw-need-write-stack?.
	* hardware.scm (used-in-delay-rtl?): New member of <hardware-base>.
	(define-getters <hardware-base>): Define used-in-delay-rtl?.
	(used-in-delay-rtl?): New method of <hardware-base>.
	(hw-used-in-delay-rtl?): New function.
