Makefile.in: Regenerate.

2004-08-17  Paolo Bonzini  <bonzini@gnu.org>

	* Makefile.in: Regenerate.
	* configure: Regenerate.

	* Makefile.def (bootstrap-stage): Rename extra_*_flags to
	stage_*_flags.
	* Makefile.tpl (configure-[+module+], all-[+module+]): Exit
	for bootstrapped modules if toplevel bootstrap is going.
	(GCC bootstrap): Generate per-stage targets for all bootstrapped
	modules.  Adjust for changes in Makefile.def.  Enable several
	rules even in non-bootstrap mode, just to avoid peppering the
	template with unnecessary "@if/@endif gcc-bootstrap" pairs.
	(stage-[+prev+]-bubble): Remove.

	* Makefile.def (Dependencies): Depend on all-build-bison,
	all-build-flex, all-build-byacc, all-build-texinfo, rather
	than the host variations.
	* Makefile.tpl (BUILD_DIR_PREFIX): Remove.  Replace throughout
	with BUILD_SUBDIR.
	(BISON): Update for recent Bisons.
	(YACC): Fix typo.
	(cross): Depend on all-build.
	(all): Do not depend on all-build.
	(prebootstrap): Remove.
	(dep-kind): Accept separate prefixes for MODULE and ON variables.
	(Prebootstrap dependencies): Add them to the per-stage targets
	and to all-prebootstrap.
	* configure.in (build_configdirs): Always enable build_tools.
	(BUILD_DIR_PREFIX): Remove.

	* Makefile.def (gcc): Add target variable.
	(gdb, expect, guile, tk, tix): Replace with_x with extra_make_flags.
	* Makefile.tpl (Autogenerated `all-*' targets): Invoke $(TARGET-*)
	in the recursive `make', instead of hardwiring `all'.
	(Autogenerated TARGET-* variables): New.

gcc/ChangeLog:
2004-08-17  Paolo Bonzini  <bonzini@gnu.org>

	* configure.ac: Trust toplevel's notion of BISON/FLEX/MAKEINFO.
	No need to check if in a cross configuration.
	* configure: Regenerate.

	* calls.c (precompute_register_parameters):
	Inline preserve_subexpressions_p ().
	* expmed.c (expand_mult_const, emit_store_flag): Likewise.
	* optabs.c (expand_binop, expand_twoval_binop, prepare_cmp_insn):
	Likewise.
	* expr.c (get_subtarget): Likewise.
	* rtl.h (preserve_subexpressions_p): Remove.
	* stmt.c (preserve_subexpressions_p): Remove.

	* dojump.c (do_jump) <COND_EXPR, EQ_EXPR, NE_EXPR,
	TRUTH_ANDIF_EXPR, TRUTH_ORIF_EXPR, COMPOUND_EXPR>:
	Abort on gimplified cases.
