Fri Dec 25 06:53:49 1992  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)

Fri Dec 25 00:03:26 1992  James Van Artsdalen  (james at bigtex.cactus.org)

	* Makefile.in (install-dir): Add missing semicolon.

	* i386sco4.h (_KR, _SVID, _NO_PROTOTYPE): Define if -traditional.

Thu Dec 24 15:02:29 1992  Richard Stallman  ([e-mail])

	* fixinc.svr4: Don't change bitfield types to int.

	* seq386.h (TARGET_DEFAULT): Override.

Wed Dec 23 20:19:17 1992  Richard Stallman  ([e-mail])

	* i386sco4.h (CPP_SPEC): Avoid repeated def of _M_SYSV.

Tue Dec 22 15:40:08 1992  Richard Stallman  ([e-mail])

	* c-decl.c (store_parm_decls): Use TYPE_MAIN_VARIANT to compare types
	when merging info from previous prototype.

	* fixinc.svr4: Add special fixes for netinet/in.h and sys/endian.h.

Mon Dec 21 02:58:27 1992  Richard Stallman  ([e-mail])

	Use switch_table_difference_label_flag.

	* configure (m68k-motorola-sysv*): Set use_collect2.

Sat Dec 19 20:19:44 1992  Richard Kenner  ([e-mail])

	* a29k.c (secondary_reload_class): Return CR_REGS for larger than
	word memory, and BP_REGS for part-word mem with no DW.

	* a29k.md: Consistently use `&' in constraint of MATCH_SCRATCH.
	Always use a reg as 4th arg of dmac/fmac even if ignored by insn.
	Uses of `b' as a constraint in multi-word reload patterns should
	be `c'.

Sat Dec 19 01:32:13 1992  Richard Stallman  ([e-mail])

	* Makefile.in (all.cross): Add `specs' as dep.

	* build-make (CC): Delete the -V option.

Fri Dec 18 20:56:59 1992  John Hassey  ([e-mail])

	* objc-actions.c (build_encode_expr):
	Terminate the encode string with a null.
	(encode_aggregate): Distinguish pointer to record from a
	record.  Output fields for record.  Fix unions.

Fri Dec 18 17:17:39 1992  Michael Meissner  ([e-mail])

	* mips.h (MIPS_VERSION): Set Meissner version # to 33.
	(struct mips_args): Add support for passing QI/HI mode structures
	the way the MIPS compiler passes them.
	(SIZE_TYPE, PTRDIFF_TYPE): Define as unsigned int, and int if not
	defined already.

	* mips.c (init_cumulative_args): Use a static structure to
	initialize the CUMULATIVE_ARGS structure.
	(function_arg_advance): Add a newline at the end of debug output.
	(function_arg): If a structure is passed as a QImode or HImode
	value in a register, record the fact for the call define_expands
	and prologue expander to move the structure into the high part of
	the register, and back again.  If debugging, print if the argument
	is a structure.
	(mips_expand_prologue): Shift any QI/HI structures passed back, so
	they can be used as normal QI/HI values.

	* mips.md (call): If there were any tiny structures passes as
	QI/HI modes in registers, shift the register, so that the
	structure value is in the high part of the register.
	(call_value): Ditto.
	(call_internal): Delete creating $31 rtx, since we can get it from
	the normal insn patterns.
	(call_value_internal): Ditto.

Fri Dec 18 05:14:14 1992  Brendan Kehoe  ([e-mail])

	Make abstract virtual functions work.
	* cp-call.c (compute_conversion_costs): Undo change of Sept 1 about
	setting HARSHNESS to 0 re: the conversion of the first argument.
	(build_method_call):  Delete the code that redid the RTL for calling
	the right fn, since we will now behave correctly.  (Even with this,
	we ended up calling the wrong fn---the base class, rather than the
	derived one.)

        * cp-decl2.c (grokclassfn): Try using the local value for a nested
        type if the IDENTIFIER_TYPE_VALUE isn't there.

	* cp-method.c (build_overload_nested_name): Use DECL_NAME instead of
	DECL_ASSEMBLER_NAME, since pushtag now mangles together
	DECL_ASSEMBLER_NAME.  This will make us emit `Q21D1B', not `Q221D1B'.

Thu Dec 17 17:51:16 1992  Roland McGrath  ([e-mail])

	* Makefile.in (install-dir): Added missing then and semicolon.

Thu Dec 17 15:19:36 1992  Richard Stallman  ([e-mail])

	Always call build_selector_translation_table.

	* Makefile.in (install-dir):
	If cross-compiler, create $(tooldir) and $(assertdir). 

Wed Dec 16 14:19:08 1992  Richard Kenner  (kenner at vlsi1.ultra.nyu)

	* rs6000.h (INITIALIZE_TRAMPOLINE): Get function address and toc
	pointer from correct place relative to FNADDR.

	(epilogue_reg_mentioned_p): New function decl.
	(mips_frame_info): Change unsigned longs to longs.
	(ELIGIBLE_FOR_EPILOGUE_DELAY): Call epilogue_reg_mentioned_p.

	* mips.c (epilogue_reg_mentioned_p): New function to return true
	if any register used in the epilogue sequence is referenced.  If
	the stack size is greater than 32k bytes, return true for
	registers $8 and $9, since they are used to hold temps.
	(compute_frame_size): Change return type & variables to long.
	(compute_frame_size): Use 1L in shifts to create GP save mask.
	(save_restore): Merge function into save_restore_insns.
	(save_restore_insns): Add FILE * argument, to write to the .s
	file if non-NULL -- otherwise produce insns.  Add arguments to
	pass in that the prologue/epilogue has loaded the stack size into
	$8 if large stack frame.  Completely rewrite large stack frame
	support, so that it doesn't abort if large stack frame, saved GP
	registers, and no saved FP registers.  If large stack frame, use
	stack size stored in $8 if we can.
	(function_prologue): Make tsize long.
	(function_epilogue): Ditto.
	(mips_expand_prologue): Ditto.
	(mips_expand_epilogue): Ditto.
	(mips_expand_prologue): Change call to save_restore_insns.
	(mips_expand_epilogue): Ditto.
	(function_epilogue): Call save_restore_insns instead of
	save_restore.

Wed Dec 16 07:33:08 1992  Richard Kenner  ([e-mail])

	* stmt.c (expand_goto): Set LABEL_REF_NONLOCAL_P in the LABEL_REF
	we make in the non-local case.

	unconditional jump when it is the last nonnote insn.

	* seq386.h (FUNCTION_PROFILER): Add missing . to label name.

	* reload1.c (eliminate_regs_in_insn): Don't recopy new_body
	if it is an asm_operands insn.

Tue Dec 15 19:42:58 1992  Jim Wilson  ([e-mail])

	patterns.
