- Subject: speed up of opcodes m32c file generation
Hi.
I checked in a patch to change the way iflds, operands, insns,
and macro-insns are stored.
It significantly speeds up opcodes m32c file generation
(by a factor of 6 to 7 on my machine).
http://sourceware.org/ml/cgen-cvs/2009/msg00075.html
Things are still not good enough, but it's progress.
Tested by regenerating all files for opcodes, sim, sid, doc, intrinsics.
[opcodes and sim will see a small change in ifield tables,
ifields f-nil and f-anyof now live in all isas, which is the right
thing anyway]
I had to add some hacks to preserve the existing output.
We can remove them at any time, but it was useful for testing.
[And if someone really needs guile 1.4 we could provide hash-fold
in guile.scm, but I'm guessing folks would rather just delete
support for 1.4.]

Use hash tables to record ifields, operands, insns, macro-insns.
* attr.scm (attr-builtin!): Tweak some comments.
* hardware.scm (hardware-builtin!): Call all-isas-attr-value.
* ifield.scm (<ifield>): Subclass from <ordered-ident> instead of
<ident>.
(<multi-ifield>): New constructor.
(ifield-builtin!): Add isa attr to f-nil, f-anyof.
* insn.scm (<insn>): Subclass from <ordered-ident> instead of
<ident>.
(-sub-insn-make!): Add hack to avoid differences in generated code.
(multi-insn-instantiate!): Add total number of multi-insns to
logging message.
* mach.scm (<arch>): Rename members ifld-list, op-list, insn-list,
minsn-list to foo-table. New member next-ordinal.
Update getters/setters.
(arch-ifld-list, arch-op-list, arch-insn-list, arch-minsn-list):
New functions.
(-get-next-ordinal!, -get-lowest-ordinal): New function.

-ident-object-table-add!, -ident-object-table-lookup): New functions.
(current-ifld-list, current-ifld-add! current-ifld-lookup,
-ifld-already-defined?): Rewrite.
(current-op-list, current-op-add! current-op-lookup,

(arch-finish!): Delete references to ifld-table, op-table, insn-table,
minsn-table.
* minsn.scm (<macro-insn>): Subclass from <ordered-ident> instead of
<ident>. New constructor.

<ident>.
* sid.scm (-virtual-insn-add!): New function.
(-create-virtual-insns!): Call it.
(-fill-sim-insn-list!): Rewrite.
* sim.scm (-virtual-insn-add!, -create-virtual-insns!): New functions.
