	(FUNCTION_ARG): Return arg count to the final VOIDmode FUNCTION_ARG
	hack that supplies "next arg register" to be stored in call insn.
	(TRAMPOLINE_TEMPLATE): Use instruction notation rather than constants.
	(INITIALIZE_TRAMPOLINE): Use gen_call_pop.
	(LEGITIMATE_CONSTANT_P): Rewrite to make clearer.
	(GO_IF_LEGITIMATE_ADDRESS): Do not use indirect addressing -- with
	insn scheduling, two loads can be faster and can't be slower.
	(SLOW_BYTE_ACCESS): Define unless C2.  Memory access to bytes is
	not actually slow, but faster processors don't forward partial
	word writes to word reads, and setting SLOW_BYTE_ACCESS
	makes the code consistently use word ops where possible.
	(CONST_COSTS): Const_DOUBLE cost is zero -- if it appears, it is
	immediate and therefore free.
	(RTX_COSTS): areg+const is free (via indexing).
	(RTX_COSTS): Provide target-dependent values for *,<<,>>
	(ADDRESS_COST): Zero.  Indirect addresses are no longer used.
	(ADJUST_COST): Define.
	(TARGET_FLOAT_FORMAT): Define as VAX_FLOAT_FORMAT.  Also
	accurately describes the semantics (not the bit pattern)
	of convex ieee mode.
	(REAL_VALUE_ATOF): Define, to prevent real.c from constructing
	vax dfloats.  Apparently it doesn't do gfloat.
	(CHECK_FLOAT_VALUE): Call convex.c.
	(ASM_FILE_START): Output appropriate .fpmode pseudo op.
	(ASM_IDENTIFY_GCC): Ouput a zero after gcc2_compiled to keep it
	from hiding the real name from profilers and adb.
	(ASM_OUTPUT_DOUBLE, _FLOAT): Use hex to avoid /bin/as conversion 
	errors.
	(ASM_DECLARE_FUNCTION_NAME): Define; call convex.c.
	(PRINT_OPERAND, _ADDRESS): Call convex.c.
	(EXIT_BODY): Define for libgcc2.  Call atexit handler if present.
	
	convex.md: Add scheduling info.
	(movxx): One of the operands must be a register.
	(movdf, movdi):	Add anonymous patterns that can load an arbitrary 
	const_double by doing two immediate loads.  This is not superior
	to loading it from memory, and can be worse, so LEGITIMATE_CONSTANT_P
	still rejects these constants, but the patterns are still useful
	so rtx folding can produce arbitrary results.
	(floatunsdidf, floatunsdisf): Add patterns that avoid double rounding.
	(floatunssidf, floatunssisf): Add patterns that mimic gcc's default
	method, to keep SI cvts from promoting to the above DI cvts.
	(fix_truncdfsi2): Use cvtd.l even if cvtd.w is available -- on c34
	cvtd.w is microcoded and slower.
	(addqi3, subqi3, mulqi3): can do immediate with word insn.
	(subsi3): use sub/neg to get reverse subtract (reduces reg shuffling).
	(udivsi3): give up on having sign_expand_binop do this; people keep
	breaking it.  Manually extend unsigned SI to signed DI, then divide.
	(xshfxx3): The options rank differently on different machines, so 
	spell them all out and enable the appropriate ones under TARGET_Cxx.
	(sqrtxx2): Put under flag_fast_math.
	(sinxx2, cosxx2): I don't know why these exist, but they do, so supply
	them.  The other microcoded intrinsics are in convex math.h.
	(txtxx): Remove, no longer necessary.
	(cmpdi): Add alternative to fake "eq.l #0,sk" with "neg.l sk,scratch".
	(cmpqi): Omit, seems to produce marginally better cse than the old way.
	(cmpsf): Avoid compare against 0.0 in ieee mode, since -0.0 is 
	possible and would confuse old ucode.
	(movstrsi): Add.
	(anon): Add patterns to pick up on dbra optimizations and implement the
	sub/test part.  (This optimizes out the compare against 0.)
	(call, call_value): Use _pop form instead, and let convex.c replace
	the pushes with fp stores.
	(end): Put local variable list back.

	convex.c (init_convex): New. Fill in tables used by convex.h.
	(psw_disable_float): New.  Turn off float exception enables to
	make the environment more ieee-like.
	(set_cmp): Change name to output_cmp.
	(gen_cmp): Change name to output_condjmp.  Add handling for
	`neg.x' as a fake `eq.x #0' and for optimized-out compares
	that read the carry of a preceding decrement.
	(simplify_for_convex): New.  Replace addr-(-const) with
	addr+const so /bin/as will like the notation.
	(expand_movstr): New.  Generate pipelined load/store sequence.
	(asm_declare_function_name): New. Output arg count for debuggers.
	(print_operand): Moved from convex.h.  Add %u and %v to fetch
	subwords of a CONST_DOUBLE, %z to use in replacing shift by mul.
	(print_operand_address): Moved from convex.h.
	(outfloat): New, call REAL_VALUE_TO_DECIMAL.
	(replace_arg_pushes): New.  Replace sp by fp if possible; this does
	not allow us to get rid of sp but stores are faster than pushes on
	new machines.
	(emit_ap_optimizations): New.  Do simple live analysis of arg pointer
	register and eliminate dead reloads.
	
	math-convex.h: removed.
	fixinc.convex: new file.

	(load HIGH patterns): Rewrite to not show DP relocation.  
	* pa.c (output_global_address): Handle (high (const (plus ...))).

Sun Jan 10 11:42:12 1993  Richard Kenner  (kenner@vlsi1.ultra.nyu.edu)

	* combine.c (make_extraction): Don't use POS < 0 as a flag
	that POS_RTX is to be used; instead use POS_RTX unless it is
	nonzero.  If POS_RTX is a constant, set POS and clear POS_RTX.
	(make_compound_operation, make_field_assignment): Pass 0 for POS
	instead of -1 when POS_RTX is nonzero.

Sat Jan  9 08:06:42 1993  Michael Meissner  (meissner@osf.org)

	* cccp.c (main): If we are creating a new dependency file with -MD

	* cp-typeck.c (build_binary_op), cp-tree.h:  Add extra convert_p
	parameter, for consistency with the C version (so we can make
	convert_to_integer independent of C or C++).
	* cp-cvt.c, cp-decl.c, cp-decl2.c, cp-except.c, cp-init.c,
	cp-typeck.c, cp-parse.y:  Fix calls to build_binary_op to pass
	the new convert_p parameter (i.e. 1).

	Fri Dec 18 19:19:28 1992  Brendan Kehoe  (brendan@lisa.cygnus.com)

	* 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'.

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

	Wed Dec 16 18:18:43 1992  Brendan Kehoe  (brendan@lisa.cygnus.com)

        * cp-typeck.c (build_unary_op): Set TREE_CONSTANT on the address of

	* cp-tree.h (CLASSTYPE_NAMES): Deleted.

	* cp-init.c (build_offset_ref): When getting ready to give an error
	about something not being a member or operator, only call
	operator_name_string when it is indeed an operator.

	* cp-decl2.c (bad_specifiers): New function.
	* cp-tree.h (bad_specifiers): Add prototype.
	* cp-decl.c (grokdeclarator): Use it in places where we had
	replicated code.

	headers for cp-*.o targets.

	* cp-search.c (get_first_matching_virtual): Use warning_with_decl,
	not error_with_decl, inside code that's only ever reached with
	-Woverloaded-virtual.

	* cp-typeck.c (c_expand_return): When building the INIT_EXPR, clear
	out the context if it's an ERROR_MARK so the back-end won't die later.

	* cp-type2.c (my_friendly_abort): Don't say anything like "please
	fix above errors", just exit quietly.

	* cp-lex.h (enum rid): Reordered for improved speed in grokdeclarator
	when it does its linear search.  RID_WCHAR is no longer in the
	search path, since it's found by hand (as are RID_INT and RID_CHAR).
	(RID_FIRST_MODIFIER): Start at RID_EXTERN now.

	* cp-parse.y (overloaddef): Warn that using `overload' is an
	anachronism.

	Wed Dec  9 08:27:13 1992  Niklas Hallqvist  (niklas at della.appli.se)

	* cp-decl.c (init_decl_processing): Make sure the "unknown type"
	typedecl gets ignored by the debuginfo generators.

	Sun Dec 13 02:38:43 1992  Brendan Kehoe  (brendan@cygnus.com)

	* cp-search.c (lookup_nested_field): Check for assignment to members
	of an enclosing class only when looking at a member, not at other
	things (like nested types).

	* cp-pt.c (type_unification): Only check that ARGS is a TREE_LIST if
	it's non-null. 

	These four are from Niklas Hallqvist:

	* cp-search.c (compute_visibility): Use the main variant when
	testing if a member function belongs in the current class.

	* cp-call.c (build_method_call): Don't look for constructors
	called by initialization inside class methods in the classes'
	bases (as opposed to inherited methods).

	* cp-typeck.c (convert_for_initialization): In the case of
	templates, make sure build_method_call knows which instantiation
	of the class template we're initializing an object of.

	* cp-decl.c (grokdeclarator): Instead of an assert, return a
	NULL_TREE if the return_type's not return_ctor.

	Sat Dec 12 23:52:25 1992  Brendan Kehoe  (brendan@lisa.cygnus.com)

	* cp-dem.c (cplus_demangle): Recognize 'S' for signed char.

	* cp-decl.c: Include sys/types.h for systems that need things for
	signal.h.

	Wed Dec  2 15:51:34 1992  Mike Stump  (mrs@cygnus.com)

	* cp-call.c (build_method_call): Don't call abort for pure virtual
	methods, instead, call the user-defined method.  Addresses of pure
	virtual methods are probably still wrong.

	Wed Dec  2 14:44:41 1992  Brendan Kehoe  (brendan@lisa.cygnus.com)

	* cp-call.c (convert_harshness): If parm's null for a reference (as

	Tue Dec  1 18:05:20 1992  Brendan Kehoe  (brendan@lisa.cygnus.com)

	* cp-decl.c (grokdeclarator): Make member initialization be a
	warning, not an error.  Only issue it if not -pedantic, since
	grokfield will issue an error when pedantic.  Only warn about
	constant members being initialized if `-ansi' is being used.
	(finish_decl): Only complain about uninitialized const's that aren't
	members when acting -pedantic, since we'll have already issued the
	error about initializing a field.

	* cp-type2.c (build_functional_cast): Revert change of Nov 2,
	concerning clearing the TREE_VALUE of a default parameter.

	Tue Dec  1 11:09:50 1992  Brendan Kehoe  (brendan@lisa.cygnus.com)

	* cp-call.c (build_method_call): When looking for a default arg
	initialized by a ctor, be careful of a null ref w/ operand 1.

	* cp-method.c (icat): Handle an argument of `1' first, since it's
	the most common case. 

	Tue Dec  1 02:36:28 1992  Mike Stump  (mrs@cygnus.com)

	* cp-search.c (get_first_matching_virtual): Only set the
	DECL_CONTEXT if the new context is a an unambiguous parent of the
	previous context.

	Thu Nov 26 11:22:12 1992  Mike Stump  (mrs@cygnus.com)

	* c++: Put a newline after for arg and before do, as ``for arg do''
	is not accepted by all shells.

	Mon Nov 23 13:21:43 1992  Brendan Kehoe  (brendan@cygnus.com)

	* c++ (-lm): Also recognize -lmath as a math library.

	* 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-parse.y (paren_expr_or_null): New rule to emit an error when an
	empty condition is used when it shouldn't.
	(simple_if, stmt): Use it for `if', `while', and `do'.

	* 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,
	rather than trying to pass NOP_EXPR down hoping it gets there intact.
	(build_modify_expr): Ditto.
	* cp-method.c (build_opfncall): Use TREE_CODE on ARG3 for a
	MODIFY_EXPR, since it'll be coming in properly as a tree now.

	Sat Nov 21 02:33:28 1992  Brendan Kehoe  (brendan@cygnus.com)

	* cp-init.c (expand_default_init): Clear DECL_REGISTER if we're
	going to call a ctor, otherwise we may end up generating bogus and
	confusing error messages about taking the addr of something declared
	to be `register'.

	* 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.

	(grokclassfn): Delete unused local var name.
	(check_classfn): Delete unused arg FLAGS.  Change all callers.
	(grokfield): Pass digest_init only 3 args, not 6 (that's in the C
	front end, dammit).
	(coerce_new_type, coerce_delete_type): Delete first arg CTYPE, it's
	never used.  Change all callers.
	* cp-dem.c (cplus_demangle): Delete unused var non_empty.

	$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.
