Subject: 	* expr.h: Split out optab- and libfunc-related code to... 
 * optabs.h, libfuncs.h: ... these new headers.

	* Makefile.in (CONFIG_H, EXPR_H): Take out insn-codes.h.
	(OPTABS_H): New.
	(various .o rules): Add $(OPTABS_H) and/or libfuncs.h to
	dependencies.
	* mkconfig.sh: Don't include insn-codes.h from config.h.

	* reload.h: Use #ifdef GCC_INSN_CODES_H to decide whether
	enum insn_code is available.  Move reload_in_optab and
	reload_out_optab array declarations to optabs.h.
	* regmove.c (gen_add3_insn): Move to optabs.c, export from
	there, prototype in expr.h.
	* gencodes.c: Cleanup: zap global variables, don't use
	printf where puts will do, don't bother defining MAX_INSN_CODE
	which nothing uses, let CODE_FOR_nothing get its value implicitly.

	* genemit.c, genopinit.c: Include optabs.h in generated file.
	* genoutput.c: Include insn-codes.h in generated file.
	* builtins.c, caller-save.c, combine.c, doloop.c, explow.c,
	expmed.c, expr.c, function.c, ifcvt.c, loop.c, optabs.c, profile.c,
	reload1.c, simplify-rtx.c, stmt.c, unroll.c, config/alpha/alpha.c,
	config/arm/arm.c, config/c4x/c4x.c, config/clipper/clipper.c,
	config/i386/i386.c, config/ia64/ia64.c, config/mn10300/mn10300.c,
	config/pj/pj.c, config/sh/sh.c, config/sparc/sparc.c:
	Include optabs.h.
	* builtins.c, calls.c, dwarf2out.c, except.c, expr.c, function.c,
	optabs.c, stmt.c, config/c4x/c4x.c, config/clipper/clipper.c,
	config/m88k/m88k.c, config/sparc/sparc.c:
	Include libfuncs.h.
	* reload.c: Include expr.h and optabs.h before reload.h.
	* config/alpha/alpha.c: Include tree.h before reload.h.
	* config/pa/pa.c: Include expr.h, optabs.h, libfuncs.h,
	and reload.h in that order.
	* config/sparc/sparc.c: Include debug.h.
	* recog.c: Include insn-codes.h.

cp:
	* Make-lang.in (cp/except.o): Add libfuncs.h to dependencies.
	* except.c: Include libfuncs.h.
java:
	* Make-lang.in (java/decl.o): Update dependencies.
	* decl.c: Include libfuncs.h, don't include toplev.h.

 /* INC_INSN is an instruction that adds INCREMENT to REG.
    Try to fold INC_INSN as a post/pre in/decrement into INSN.
    Iff INC_INSN_SET is nonzero, inc_insn has a destination different from src.
