早期freebsd实现

Sun Dec  6 16:27:14 1992  Richard Kenner  ([e-mail])

	* alpha.md (add-mult): Add missing `&' in constraints of kludge
	plus/plus/mult pattern.

Sun Dec  6 16:26:42 1992  Richard Stallman  ([e-mail])

	* optabs.c (expand_binop): Correct sign of complex quotient imagpart.

Sun Dec  6 07:59:16 1992  Michael Meissner  ([e-mail])

	* mips.h (MIPS_VERSION): Set Meissner version # to 30.
	(LEGITIMIZE_ADDRESS): For <reg>+<large int> addresses, rewrite so
	that <reg> + (<large int> & ~0x7fff) is put into a pseudo reg.
	This is to allow CSE to generate better code for repeated
	references in the same general vicinity, such as when large stack
	frames are used.

	* config/dec-osf1.h (LINK_SPEC): Pass -call_shared, -no_archive,
	and -exact_version to the linker.  If -call_shared, do not pass
	-non_shared to the linker.
	* mips-5.h (LINK_SPEC): Ditto.
	* mips-5bsd.h (LINK_SPEC): Ditto.
	* mips-svr4.h (LINK_SPEC): Ditto.
	* mips-sysv.h (LINK_SPEC): Ditto.

	* c-decl.c, cp-decl.c (init_decl_processing): Don't use hardwired
	sizes for the modes when making int{Q,H,S,D}I_type_mode and the
	unsigned versions of them; the actual size depends on BITS_PER_UNIT.

Fri Dec  4 19:13:35 1992  Jonas Olsson  ([e-mail])

	* rs6000.h (LINK_LIBGCC_SPECIAL): No longer define.

	* stmt.c (expand_value_return): Don't emit move between differing
	modes when PROMOTE_FUNCTION_RETURN is defined; convert instead.

	* integrate.c (expand_inline_function): Ensure a REG used as
	COPY has REG_USERVAR_P set if LOC does.

	* optabs.c (expand_binop, expand_twoval_binop): If we are going
	to fail, remove any load from MEM we did due to -fforce-mem;
	if the MEM was volatile, this will cause an extra load.
	(expand_complex_abs): Likewise.
	Correct use of variable LAST so it doesn't include the load
	from MEM (to fix unrelated bug).

	Mon Nov 23 13:21:43 1992  Brendan Kehoe  ([e-mail])

	* c++ (first): Only shift if $first is no, on the chance we got no
	arguments at all.  If we didn't get anything, say so (since -lg++
	will fake out the gcc driver into thinking we want to do something).

	* cp-decl.c (start_decl): If grokdeclarator returns a
	void_type_node, return a NULL_TREE.

	* cp-typeck.c (build_modify_expr_1): When calling build_opfncall for
	`operator=', use make_node to create a plain NOP_EXPR for it to use,

	* cp-parse.y (expr_no_commas): Ditto.
	* cp-method.c (build_opfncall): Use TREE_CODE on ARG3 for a

	* cp-init.c (expand_default_init): Clear DECL_REGISTER if we're

	* cp-typeck.c (build_x_function_call): Recognize a ptr-to-method
	that is being passed in as a function argument or as part of
	a COMPONENT_REF.
	(build_indirect_ref): If ERRORSTRING is NULL (it's passed in that
	way in many places), then don't try to use it.

	Thu Nov 19 01:41:58 1992  Brendan Kehoe  ([e-mail])

	* cp-dem.c (do_builtin_type): Recognize `w', a wide character, since
	it's now a type according to the ANSI X3J16 working paper; output
	"wchar_t" for it.
	(cplus_demangle): Accept `w' as an integral type.

	Wed Nov 18 21:29:14 1992  Brendan Kehoe  ([e-mail])

 	* cp-class.c (finish_struct): Re-enable code to cut down on the size

Mon Nov 23 18:29:27 1992  Jim Wilson  ([e-mail])

	* genattrtab.c (obstack.h): Include after sys/time.h.

	* c-decl.c (duplicate_decls): For builtins, create new function
	type instead of trying to modify old one.

	* c-decl.c (c_decode_option): Decode -Wreturn-type.

	* c-decl.c, cp-decl.c (pushdecl): Don't inherit DECL_INITIAL when
	redeclaring the current function.

	* integrate.c (expand_inline_function): Use the original
	declaration of the inlined function rather than a redeclaration as
	the BLOCK_ABSTRACT_ORIGIN of the body.

Sat Nov 21 19:54:57 1992  Richard Stallman  ([e-mail])

	* cccp.c (main): Do -D's and -A's and -U's in order specified.
