+	directive.
+	(ENCODE_SECTION_INFO): Encode function labels.
+	(ASM_OUTPUT_LABELREF): Deal with function labels.
+	(ASM_OUTPUT_REG_PUSH, ASM_OUTPUT_REG_POP): Don't do anything for
+	now; their only use (saving stuff during profiling) interacts in a
+	wierd way with required assembler directives at the start of a
+	function.  Instead, do the save and restore in the function
+	prologue.
+	(hppa_encode_label): Declare.
+	* pa-hpux.h, pa-ghpux.h (TARGET_DEFAULT): Link against shared
+	libraries.
+	(LINK_SPEC): Don't link against shared libraries if debugging or

+
+	Major rework to have caller-saves emit load/store double insns when
+	possible and to avoid useless resaving of registers restored for
+	source accesses only.
+	* caller-save.c (toplevel): All arrays are multi-dimensional to
+	hold information for multiple save/restore insns.  New variable
+	hard_regs_need_restore.
+	(choose_hard_reg_mode): New argument `nregs' indicating how many
+	hard registers are desired.  All callers changed.
+	(init_caller_save): Change initialization to handle multiple
+	register saves.  A call-used register can not be live across
+	if we can not find a single register mode to save it in.
+	(multiple register saves are optional)
+	(init_save_areas): Change initialization of regno_save_mem to
+	handle multiple register saves.
+	(setup_save_areas): Allocate space for consecutive hard registers
+	in aligned consecutive memory locations.   When allocating space
+	for consecutive hard registers, also initialize regno_save_mem
+	for each hard register stored as a single word.
+	(save_call_clobbered_regs): Initialize hard_regs_need_restore.
+	Set hard_regs_need_restore to hard_regs_saved after crossing
+	a call.  Also recompute n_regs_saved.  At the end of a basic block
+	we need only restore registers in hard_regs_need_restore.
+	(set_reg_live, clear_reg_live): Do the right thing for 
+	hard_regs_need_restore and hard_regs_saved.
+	(restore_referenced_regs): Just return if X is a clobber.
+	Test hard_regs_need_restore to determine when to restore a hard
+	register from the save area.
+	(insert_save_restore): Now returns the number of extra registers
+	saved/restored.  New argument `maxrestore' which constrains how
+	many hard registers should be restored.  All callers changed.
+	Do stores of consecutive registers with double store insns if
+	possible.  Else do them with single word insns. Likewise for
+	loads, except constrained by maxrestore.  Set hard_regs_saved
+	and hard_regs_need_restore appropriately to minimize useless
+	saves into the save area.  Test against	hard_regs_need_restore
+	when trying to restore multiple regs and similarly test against
+	hard_regs_saved when storing multiple regs.

+	* mips.h (MIPS_VERSION): Set Meissner version # to 24.
+	(ASM_FINAL_SPEC): Use %U to get the last file name created with
+	%u, rather than %u.
+	(ARG_POINTER_REGNUM): Use the hardwired register $0 as the
+	argument pointer, instead of the frame pointer, to allow the frame
+	pointer to be the same as the stack pointer after the initial
+	stack allocations.  This is to allow GCC generated code to be
+	linked against MIPS shared libraries.  The linker rearranges the
+	code, and needs to have a frame pointer, if used, to be the same
+	as the stack.  The argument pointer is always eliminated in favor
+	of the stack pointer or frame pointer.
+	(FRAME_GROWS_DOWNWARD): Don't define this any more.
+	(STARTING_FRAME_OFFSET): Locals start after the stack area to pass
+	arguments to called functions.

+
+	* mips.c (number_functions_processed): Delete variable, nobody
+	uses it anymore.
+	(mips_debugger_offset): Add support for the frame pointer being
+	the same as the stack pointer, instead of being the same as the
+	argument pointer.  Abort if the address is not based on any of the
+	stack, frame, or argument pointers.
+	(print_operand_address): Add checks for the arg pointer not being
+	eliminated.
+	(function_prologue): Ditto.
+	(mips_expand_prologue): Ditto.
+	(function_epilogue): Ditto.
+	(mips_expand_epilogue): Ditto.
+	(function_epilogue): Strip leading '*' if it exists from
+	current_function_name when printing statistics.  Delete increment
+	of number_functions_processed.
+	(compute_frame_size): Don't base extra_size on the macro
+	STARTING_FRAME_OFFSET.  If function is a leaf function, but calls
+	__builtin_alloca, allocate an arg area, so that the MIPS linker
+	will not complain about creating a second frame pointer.  Move the
+	argument save area beneath local variables.
+
+	* decrose.h (ASM_FINAL_SPEC): Use %U to get the last file name
+	created with %u, rather than %u.
+
+	* gcc.c (do_spec_1): Add %U to return the last name generated with
+	%u.  This is for use with mips-tfile, to find the generated object
+	file.

+
+Mon Aug 24 13:52:13 1992  Brendan Kehoe  (brendan@cygnus.com)
+
+	* gcc.c (process_command): Don't set verbose_flag if they make a
+	typo (e.g., `-v-E'); only when it's exactly "-v".
+
+Mon Aug 24 06:49:16 1992  Richard Kenner  (kenner@vlsi1.ultra.nyu.edu)
+
+	* combine.c (subst): When moving operation inside IF_THEN_ELSE,

+
+	* decrose.h (CPP_SPEC): Don't define strcmp as __builtin_strcmp in

+	(gen_insn): Don't emit function declarations here, just save the
+	insn on either the call_obstack if it is call or call_value, or
+	normal_obstack otherwise.
+	(main): Initialize call_obstack, normal_obstack.  After all insns

+
+	* pa.h (ASM_FILE_START): If profiling IMPORT "_mcount" instead of 
+	"__gcc_mcount".

+	Fri Jul 31 16:53:26 1992  Mike Stump  (mrs@cygnus.com)
+
+	* cp-tree (break_out_calls): Only make ony copy of a node on
+	's' and 'e' nodes.  Handle 'r' just like 's' and 'e' because
+	nodes of type 'r' can be of different sizes (the old code

+
+	* cp-decl.c (grokdeclarator): In SCOPE_REF case, sort out visibility

+
+	* cp-pt.c (end_template_instantiation) YYDEBUG is now defined in
+	cp-parse.h -- so don't assume that it's -2 (since under byacc it is

+
+	* cp-typeck.c (build_c_cast):  Allow cast to array type in

+
+	* cp-tree.c (break_out_calls): Don't do anything special to

+
+	* c++:  Fix errors introduced by rms.  Bullet-proof handling

+	alone, until we've figured out how to handle their interaction
+	properly:
+	* cp-parse.y (template_instantiate_once): Temporarily set interface
+	flags to `unknown' while processing member templates.
+	* cp-decl.c (grokfndecl): Even if class vtable is getting written
+	out, regardless of interface setting of class and write_virtuals

+	* cp-tree.h (struct pending_inline): New field `interface'.
+	* cp-lex.c (do_pending_inlines): Restore interface flags from stored

+
+	* cp-typeck.c (mark_addressable): If we have a recursive call to an

+
+	* cp-parse.y (template_instantiate_once): Set
+	CLASSTYPE_GOT_SEMICOLON to eliminate messages about missing
+	semicolons.
+
+	* cp-decl.c (start_function): Don't emit error message for missing
+	semicolon after class decl; that syntax (declaring both class and
+	function returning that type) should be legal.  Do emit a warning if

+	* cp-decl.c (pushdecl): Re-fix May 12 change regarding DECL_CONTEXT.
+	* cp-call.c (build_method_call): Go back to using DECL_CONTEXT
+	instead of DECL_CLASS_CONTEXT.  DECL_CONTEXT says when a function
+	was first declared virtual in a class, which is needed information
+	in case the virtual function comes from a virtual baseclass (because
+	the derived class won't have a vtable entry for that function (if it
+	has a vtable at all!)).

+

+
+	Mon May 18 17:19:39 1992  Mike Stump  (mrs at rtl.cygnus.com)
+
+	* cp-search.c (get_binfo): Since unions cannot participate in
+	inheritance relationships, return 0 instead of aborting.
+
+	Fri May 15 13:37:40 1992  Mike Stump  (mrs at cygnus.com)
+
+	* cp-parse.y (template_type_name): Handle

+
+	Mon May 11 14:10:50 1992  Ron Guilmette (rfg at ncd.com)
+
+	* cp-decl.c (poplevel): Reconciled with recent changes made to the
+	`poplevel' routine in c-decl.c.  The changes here cause LABEL_DECL
+	nodes to be attached (as the BLOCK_VARS chain) to the BLOCK node
+	which represent the outermost scope of the function.
+
+	Mon May 11 12:35:44 1992  Ron Guilmette  (rfg at ncd.com)
+
+	* cp-class.c (finish_struct): Check DECL_CONTEXT to see if it is

+	just as is done in c-decl.c.
+	(pushdecl): Delete useless variable `cntxt'.
+	(finish_decl): Set TREE_USED rather than DECL_FROM_INLINE in order
+	to prevent "unused" warnings.
+	(finish_function): Check DECL_CONTEXT to see if it is a type.
+	(finish_function): Fixed indentation problem.

+	* cp-pt.c (tsubst, do_pending_expansions): Check DECL_CONTEXT to see
+	if it is a type.
+	* cp-typeck.c (mark_addressable): Check DECL_CONTEXT to see if it is
+	any sort of a type (e.g. struct *or* union) rather than just

+
+	Tue May 12 08:52:06 1992  Michael Tiemann  (tiemann@rtl.cygnus.com)
+
+	* cp-typeck.c (build_component_ref): Call `break_out_cleanups'.
+	Also clean up indentiation.
+
+	Mon May 11 23:14:04 1992  Mike Stump  (mrs at cygnus.com)
+
+	* cp-decl.c (pushtag): Handle structure tags in the same way as the
+	C front-end.  This completes a change that rms put in on 3/12/92 and
+	I put in the Cygnus tree on 3/13/92 and Mark Eichin took back out on
+	3/18/92.
+
+	Sun May  3 00:29:59 1992  Mike Stump  (mrs at cygnus.com)
+
+	* cp-lex.c (copy_lang_decl, store_pending_inline): Cast

+	Fri May  1 12:22:31 1992  Michael Tiemann  (tiemann@cygnus.com)
+
+	* cp-init.c (expand_aggr_init, expand_vec_init): When comparing
+	array types, use `comptypes' instead of ==, since two array types
+	may be structurally identical but not == if one was defaulted from
+	an initializer.
+
+	Wed Apr 29 01:25:25 1992  Mike Stump  (mrs at cygnus.com)
+
+	* cp-init.c (do_friend): Check that PREVIOUS_DECL is non-NULL.
+
+Thu Jun 18 14:15:07 1992  Torbjorn Granlund  (tege@hal.gnu.ai.mit.edu)
+
+	* pa.md (insv): Use `+' for operand 0 constraint.
+
+Thu Jun 18 13:39:22 1992  Michael Meissner  (meissner@osf.org)
+
+	* mips.h (MIPS_VERSION): Bump Meissner version # to 20.
+	(final_prescan_insn): Add declaration.
+	(FINAL_PRESCAN_INSN): Just call final_prescan_insn.
+	(CONST_OK_FOR_LETTER_P): Rewrite some tests, so that they will
+	work on host systems with 64 bit integers.
+
+	* mips.c (large_int): Rework, so that we don't get funny boundary
+	conditions on systems with 64 bit integers.
+	(mips_move_1word): Just use li to load constants that can be done
+	with lui, instead of issuing the lui, since the GAS bug that
+	generated two instructions has been fixed.
+	(final_prescan_insn): Move the checking for filling the delay
+	slots here from the FINAL_PRESCAN_INSN macro.
+
+	* mips.md (andsi3, iorsi3, xorsi3): Make the constraints match
+	the real machine (the predicate still is more general in order
+	to optimize bitfields at the expense of not CSE'ing large
+	constants used in logical ops, and making reload load it into
+	a scratch register).  Don't use $1 as a temporary register any
+	more.
+
+	* varasm.c (decode_reg_name): If `memory' return -4.
+
+	* stmt.c (expand_asm_operands): If `memory' is used as a clobbered
+	register, emit a (clobber (const_int 0)) to force the compiler not
+	to cache memory values in registers across the assembly
+	instruction(s).
+
+	* mips-tfile.c (read_line): Semicolons within strings are not
+	counted as statement separators.
+
+	* collect2.c (scan_prog_file, OSF/rose case): Cast pointer arguments
+	to bcopy to generic * to avoid warnings.
+
+Thu Jun 18 12:04:53 1992  David J. MacKenzie  (djm@wookumz.gnu.ai.mit.edu)
+
+	* c++: If given -v with no file args, don't pass the libraries to
+	gcc.
+
+Thu Jun 18 10:34:22 1992  Tom Wood  (wood@dg-rtp.dg.com)
+
+	* expr.c (expand_builtin, BUILT_IN_FSQRT): Emit queue of increment
+	instructions before starting a sequence that may get thrown away.
+
+See ChangeLog.5 for earlier changes.
