Wed Jun  3 14:35:00 1992  Tom Wood  (wood at gen-rtx)

	* c-lex.c (yylex): Let skip_white_space handle \r.

	* expr.c (expand_builtin, fsqrt case): Stabilize the argument in
	case a library call is done.

	* final.c (final_scan_insn): Function begin, and block begin/end
	notes are "real" in that they depend on the current line number.

Wed Jun  3 14:34:28 1992  Michael Meissner  ([e-mail])

	* mips.md (andsi3_internal2): Fix typo in previous change, to
	use %3, the clobbered register, instead of %@, the assembler
	temporary.
	(iorsi3_internal2): Ditto.
	(xorsi3_internal2): Ditto.

	* mips.h (MIPS_VERSION): Bump Meissner version # to 20.
	(final_prescan_insn): Add declaration.

	LUI instruction.
	(final_prescan_insn): Move the checking for filling the delay
	slots here from the FINAL_PRESCAN_INSN macro.  If the safe
	attribute is set, we do not need a NOP to fill a load delay slot.

	* mips.md (safe attribute): New attribute to indicate that the
	current insn is safe to fill a delay slot even if the register
	operand(s) are set in the load instruction which has the delay
	slot.  This is for and/ior/xor expansions that have a large
	constant integer as operand[2].  The load of the constant can
	overlap the load.
	(andsi3, iorsi3, xorsi3): Replace logical define_insn's with
	define_expand's that either map directly to the hardware
	instruction, or have a clobbered register to load the large
	constant into.  This is instead of using $1 to hold the
	intermeidate value.  Set the safe attribute to yes for the cases
	where we need to load the integer.  Add define_split's to break
	the large logical operations into the separate pieces.

Wed Jun  3 00:00:36 1992  Richard Stallman  ([e-mail])

	* cccp.c (do_warning): Do just a warning, not an error.

	* cse.c (cse_basic_block): When a jump becomes unconditional, 
	check whether this caused TO to be deleted.

Tue Jun  2 16:11:42 1992  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)

        * combine.c (subst, case IF_THEN_ELSE): Don't try reversing
        something that isn't a comparison.

Tue Jun  2 16:50:47 1992  Jim Wilson  ([e-mail])

	* cccp.c (do_pragma): Don't warn about #pragma once if used in a
	system header file.

Tue Jun  2 15:21:07 1992  Michael Meissner  ([e-mail])

	* mips.h (MIPS_VERSION): Bump Meissner version # to 19.
	(ASM_OUTPUT_DOUBLE): Call mips_output_double.
	(ASM_OUTPUT_FLOAT): Call mips_output_float.

	* mips.c (mips_output_double): If REAL_VALUE_TO_TARGET_DOUBLE is
	defined, use it to split the floating point value into 2 long
	integers, and print them out in hex.  Otherwise use .double.
	(mips_output_float): If REAL_VALUE_TO_TARGET_FLOAT is defined, use
	it to split the floating point value into a long integer, and
	print in out in hex.  Otherwise use .float.

	* dec-osf1.h (new file): Config file for DEC's offical OSF/1
	product (as opposed to the OSF/1 reference port from OSF).

	* configure: Support mips-dec-osf1 target.
	* config.sub: Support mips-dec-osf1 target.

	* decstatn.h (CPP_PREDEFINES): If CPP_PREDEFINES is defined, don't
	supply another definition.  Also, define _SYSTYPE_BSD.
