-Thu May 10 22:48:31 1990  Richard Kenner  (kenner at vlsi1.ultra.nyu.edu)
-
-	* rtl.def (DEFINE_DELAY): Change description to describe annulling.
-
-	* genattr.c (main): Write out definitions for annulling, if present.
-
-	* genattrab.c (expand_delays): Build internal attributes for
-	which insns can be annulled in a delay slot.
-	(gen_delay): Validate number of elements in DEFINE_DELAY list.
-	(write_eligible_delay): Write out routines for validating annulled
-	insns as well as those in normal delay slot.
-	(main): Call write_eligible_delays to output annulling information,
-	if it exists for this machine.
-
-	* out-m68k.c (not_sp_operand): New function.
-	* m68k.md (andsi3): Don't allow sp as ourput to avoid reload
-	inefficiency.
-
-	* calls.c (struct arg_data): Delete field STORED; add fields
-	PASS_ON_STACK and SAVE_AREA.
-	(prepare_call_address): Static chain value can't have QUEUED.
-	(expand_call): Rework to support additional calling sequence options.
-
-	Major changes include:
-	Call FUNCTION_ARG_PASS_BY_REFERENCE to determine whether an 
-	object should be passed by invisible reference.
-	Handle arguments passed both on stack and in a register; this can be
-	used to allow arguments that are hard to compute directly into
-	registers to be passed.
-	Support option (ACCUMULATE_OUTGOING_ARGS) where the largest amount
-	of stack for outgoing arguments is computer and pushed during the
-	function prologue.  Stack space usage is tracked and any location
-	that would need to be reused will be saved and restored.
-	If preallocating arg block, compute address where each arg will be
-	placed and pass it as target to expand_expr.
-
-	Other changes:
-	Use virtual regs to see if structure value address isn't stable.
-	If inlined, return TARGET if TARGET and TEMP are equivalent.
-	UNNAMED_ARGS_IN_REGISTERS is redundant with the NAMED parameter to
-	FUNCTION_ARG and has been deleted.
-	Use virtual_outgoing_stack_rtx instead of FIRST_PARM_CALLER_OFFSET.
-	Use locate_and_pad_parm to compute any needed padding for argument.
-	If REG_PARM_STACK_SPACE is defined, allocate backing stack locations
-	for args passed in registers; these are not included in the length
-	of stack space required unless OUTGOING_REG_PARM_STACK_SPACE is also
-	defined.
-	When precomputing register parameters, can stop computation when we
-	obtain any rtx, not necessarily a register.
-	No longer need code to protect data written below bottom of stack;
-	this is taken care of by preexpanding calls in argument.
-	target_for_arg no longer needed; its function is performed by
-	store_one_arg.
-	Always copy function return result to our target since they cannot
-	possibly be the same.
-	(target_for_arg): No longer used.
-	(store_one_arg): Save and restore in-use argument list location.
-	Support args passed both in register and on stack.
-	No need for explicit code for preallocated area; now pass location
-	as target to expand_expr; only copy if result in different place.
-	Put sequence point after expanding one value.
-
-	* cse.c (struct write_data): Add bit to indicate stack pointer changed.
-	(canon_hash): Allow recording of stack pointer.
-	(cse_insn): Indicate stack pointer invalidated by subroutine calls.
-	Pass stack push and pop operations to note_mem_written.
-	Process stack pointer assignment as normal operation.
-	Finish change of April 7th that excludes ap and fp from being marked
-	as clobbered by calls.  Also exclude sp; if it is clobbered by a
-	call, an explicit CLOBBER will be written.
-	(note_mem_written): Look for adjustment of stack pointer.
-	(invalidate_from_clobbers): Invalidate stack pointer, if required.
-
-	* emit-rtl.c (gen_inline_header_rtx): Add field for outgoing args size.
-	(copy_rtx_if_shared): Check for any virtual register instead of frame
-	or argument pointer.
-	(init_emit): Start normal pseudos after virtual pseudos.
-	Copy the unique virtual regs into regno_reg_rtx.
-	(init_emit_once): Incoming and outgoing static chain can be the same;
-	inlining of nested functions won't need the distinction.
-	Create unique copies of virtual registers.
-
-	* explow.c (memory_address): Don't worry about refs to fp or ap;
-	force_reg knows how to handle them correctly.
-	(fix_lexical_addr): Moved to function.c
-	(adjust_stack, anti_adjust_stack): Do nothing for adjustment of zero.
-	(allocate_dynamic_stack_space): New function copied from
-	expand_builtin.  Handle STACK_POINTER_OFFSET via
-	virtual_stack_dynamic_rtx.  When STACK_POINTER_OFFSET is defined,
-	perform alignment by always reserving a multiple of STACK_BOUNDARY
-	stack bits.  This avoids concern about whether sp itself or the top of
-	stack needs to be aligned; if we start with an aligned stack, we keep
-	it aligned.
-	(round_push): Use ADD and AND rather than DIV and MULT.
-
-	* expr.c (init_expr): Initialize some more vars.
-	(push_block): Use virtual_outgoing_args_rtx so don't need
-	STACK_POINTER_OFFSET here.
-	Merge extra and size more efficiently; no need to call force_operand
-	since memory_address is called.
-	(emit_push_insn): Pass type for FUNCTION_ARG_PADDING.
-	Use REG_PARM_STACK_SPACE instead of FIRST_PARM_CALLER_OFFSET.
-	To see if must copy address, check if it is a virtual register that
-	will be mapped to sp; only need check if not accumulating space
-	space for outgoing parms.
-	Ignore EXTRA if argument block has already been allocated.
-	(emit_library_call): Major rework to support calling sequences similar
-	to expand_call in calls.c, but only support a very small subset of
-	the conventions; abort if something outside our subset occurs.
-	Abort if incorrect mode is passed; we can't convert here since we don't
-	know the signedness.
-	(store_field): Check for virtual registers instead of hard registers
-	when seeing if stable.
-	(safe_from_p): Location in outgoing stack area is known to be safe.
-	(expand_builtin, BUILT_IN_ALLOCA): Use allocate_dynamic_stack_space.
-
-	* expr.h: Define current_function_outgoing_args_size and
-	locate_and_pad_parm; delete definition of get_structure_value_addr.
-	(ARGS_SIZE_RTX): Always return a valid operand.
-	(ARGS_SIZE_TREE): New macro.
-	(FUNCTION_ARG_PADDING): Accept MODE and TYPE like other
-	FUNCTION_ARG_... macros.
-	(FUNCTION_ARG_BOUNDARY): Provide default for new macro.
-	(MUST_PASS_IN_STACK): New macro.
-	(allocate_dynamic_stack_space): New function.
-	* tm-3b1.h, tm-3b1g.h, tm-apollo68.h, tm-crds.h, tm-mot3300.h:
-	Change definition of FUNCTION_ARG_PADDING to use TYPE instead of SIZE.
-
-	* function.c (current_function_outgoing_args_size): New var.
-	(arg_pointer_save_area, virtuals_instantiated): Likewise.
-	(invalid_stack_slot): No longer used.
-	(push_function_context, pop_function_context): Save and restore
-	outgoing args size and arg pointer save area.
-	No longer save or restore invalid_stack_slot.
-	(pop_function_context): Set up variables whose value is constant
-	throughout rtl generation.
-	(get_frame_size): No longer adjust by STARTING_FRAME_OFFSET.
-	(assign_stack_local): Use virtual_stack_vars_rtx instead of fp
-	until virtuals have been instantiated, then use fp.
-	Remove reference to obsolete invalid_stack_slot.
-	Can no longer be called with size == 0.
-	(assign_outer_stack_loc): Use virtual_stack_vars_rtx instead of fp.
-	Remove references to obsolete invalid_stack_slot.
-	Push to obstack of containing function when allocating rtx.
-	(put_var_into_stack): Only switch obstacks around making of
-	queue entry.
-	Replace call to parm_stack_loc with reference to info in proper
-	function.
-	(fixup_stack_1): Handle any virtual register instead of handling
-	just fp.
-	(instantiate_virtual_regs, instantiate_virtual_regs_1): New functions.
-	(use_variable, use_variable_after): Check for virtual register
-	instead of checking against ap and fp.
-	(parm_stack_loc): Function deleted.
-	(assign_parms): No longer need internal_arg_pointer.
-	Accept SECOND_TIME argument that suppresses rtl generation and
-	assignments to DECL_RTL.  Used by integrate.c to recompute vars.
-	Don't use FIRST_PARM_OFFSET here; use virtual_incoming_args_rtx.
-	Replace test for nonstable incoming arg pointer.
-	If structure value address is treated as the first argument, add
-	it into the list of arguments; this means we can have a RESULT_DECL
-	in with the PARM_DECL's.
-	DECL_OFFSET is no longer needed by integrate.c.
-	Handle args passed by invisible reference.
-	Support new macro, SETUP_INCOMING_VARARGS, to save all registers used
-	for args including and beyond those for the current arg.  Used for
-	non-ANSI varargs.
-	Pass locate_and_pad_parm data it needs to handle reg->stack boundary
-	if register parameters have assigned stack space.
-	If we received the function's incoming structure pointer as a
-	normal argument, update DECL_RTL of DECL_RESULT.
-	Round total argument size if required; similarly, always use at
-	least REG_PARM_STACK_SPACE bytes if defined.
-	(locate_and_pad_parm): Do not need PARM.
-	Major rework to do much of the job of aligning and padding stack
-	location.  Now a void function wich is passed pointers to struct 
-	args_size vars that are set to the argument position, size, and
-	initial offset.
-	Accept flag denoting if a parm was passed in a register and also
-	the current function declaration.
-	If register parameters are assigned stack locations and there is a
-	minimum required size for the area assigned to register parameters,
-	pad the stack position when a parameter not assigned to a register
-	is encountered.
-	Remove redundant code in MAX_PARM_BOUNDARY case.
-	(lookup_static_chain): Use virtual_stack_vars_rtx instead of fp.
-	(fix_lexical_addr): Move from explow.c.
-	If referencing variable that lives in the incoming argument area
-	of its parent and a separate ap is required, allocate a save area in
-	the parent for it and use it here.  If no separate ap is require,
-	compute offset between ap and fp.
-	(trampoline_address): No need to push obstacks here.
-	(init_function_start): Initialize new vars; delete obsolete vars.
-	(expand_function_start): Don't need to handle case where incoming
-	structure return address is passed as hidden parameter here; now done
-	completely in assign_parms.
-	(expand_function_end): Save ap if a save area was made for it.
-	Set REG_FUNCTION_VALUE_P when copying address of returned
-	structure.
-	Be consistent in use of FUNCTION_... macros vs. hard_function_value.
-
-	* function.h (outgoing_args_size, arg_pointer_save_area): New fields.
-	(invalid_stack_slot): Obsolete, deleted.
-
-	* integrate.c: Major rework and simplification.
-	Split up vars into two classes.  Those used for expand_inline_function
-	and children are now part of struct inline_remap.  Most of the others
-	are for save_for_inline and its children.
-	(function_cannot_inline_p): The only type of arguments that will
-	cause us to reject inlining are variable-sized arguments; also
-	reject functions that return variable-sized objects.
-	For now, don't inline a nested function.  We'll support this shortly.
-	Use current_function_returns_pcc_struct instead of duplicating test.
-	(save_for_inline): No need to set TREE_VOLATILE for parms.
-	Save outgoing args size in header.
-	Use unique copy of virtual reg rtx's.
-	Handle any required fixups for INSN_LIST forward-references.
-	Don't bother resetting dead static vars when we are done.
-	Need not save current_function_pretend_args_size.
-	(copy_for_inline): First copy all insns, then all REG_NOTES to avoid
-	problems with forward references.
-	(struct inline_remap): Move all previously-static vars used by
-	expand_inline_function and children into this structure.  This avoids
-	potential problems due to recursive calls to expand_inline_function.
-	(expand_inline_function and children): Allocate a struct inline_remap
-	and pass to all children.
-	(expand_inline_function): Rework parameter handling by looking at
-	DECL_RTL and using it to determine what types of mappings need to be
-	done.  Support objects passed by invisible reference.  Put any
-	constant memory addresses into const_equiv_map.  parm_map is no longer
-	used.
-	Likewise for the return value: consult DECL_RTL (DECL_RESULT)).
-	Don't allocate space for called function's frame until referenced.
-	No longer need special handling for insn following CALL.
-	Ignore USE whose argument has REG_FUNCTION_VALUE_P true.
-	Ignore setting function register if we don't have a mapping for it
-	(e.g., we are ignoring the result of the call).
-	Look at new SET_SRC for constant equivalences.  Some new ones may
-	have resulted from constant folding.
-	Pass both new and old rtx to try_constants.
-	Discard NOTE_INSN_DELETED notes.
-	Copy insns first, then REG_NOTES, to avoid problems with forward refs.
-	(copy_parm_decls): Compute new address of parameter using the
-	constant equivalence map, which will contain the remapping of
-	the frame and argument pointer.
-	(copy_decl_tree): Likewise.
-	(copy_rtx_and_substitute): Handle references to frame and argument
-	pointers by allocating a space equal to the size of the frame and
-	incoming arguments, respectively, and setting a pseudo to point to
-	the start of each area.  Set up an equivalence in CONST_EQUIV_MAP
-	between fp or ap and the actual address.  Return the pseudo.
-	Don't need to deal with possibility of (SUBREG (CONST_INT)) since
-	we are only replacing register with other registers here.
-	No longer need to special-case PLUS and MEM;  subst_constants will do
-	this work.
-	Update detection of sets of ap and fp.
-	(try_constants, subst_constants): Accept old and new rtx.  They will
-	be isomorphic, with only register numbers changed.  Use old rtx to
-	look up register in CONST_EQUIV_MAP and new rtx for substitution.
-	Correctly handle SUBREG of CONST_INT and CONST_DOUBLE.
-	Fix typos in handling of PLUS.
-	(access_parm_map, copy_address): Delete functions.
-	(try_fold_cc0): Handle both compare and test.
-	(fold_out_cnst_cc0): Rework to simplify and remove dubious cases.
-	(output_inline_function): Call assign_parms to perform any needed
-	setups.
-	Need not restore pretend arg size (will be computed by assign_parms).
-	Restore outgoing argument size.
-
-	* output.h (current_function_outgoing_args_size): New var.
-
-	* rtl.h (OUTGOING_ARGS_SIZE): New field in INLINE_HEADER.
-	(PRETEND_ARGS_SIZE): No longer needed.
-	(virtual_..., VIRTUAL_...): Define virtual register numbers and rtx.
-
-	* rtlanal.c (rtx_equal_p): Update comment on use of
-	REG_FUNCTION_VALUE_P.
-
-	* stmt.c (expand_goto): Just restore fp; non-local goto handler
-	will restore ap if needed.
-	(expand_return): Don't use STARTING_FRAME_OFFSET here.
-	(expand_end_bindings): Adjust fp in nonlocal-goto handler.  If needed,
-	reload ap from its save area in the frame; allocate save area if none.
-	(expand_decl): Use new function allocate_dynamic_stack_space.
-
-	* toplev.c (rest_of_compilation): Instantiate virtual registers.
-	Clear rtx_equal_function_value_matters immediately after possibly
-	saving current routine for inlining.
-
-	* stupid.c (stupid_life_analysis): Don't try to allocate virtual
-	registers (which don't exist any more).

-	higher numbered mode of the same mode class.
-	  NOTE: the checks for VOIDmode ops which were present in
-	QI and HI to SI widening are now present in all widening.
-	I assume this is correct.  Also, widening is now possible

-	(strength_reduce): Update and test `init_insn' instead.
-	Use of a biv between its init and the start of the loop
-	does not preclude its elimination from the loop.
-	Setting a giv is ok for eliminating a biv, even if giv is "ignore",
-	since that just means giv will be combined with another.
-	Handle some DEST_ADDR givs for that purpose.
-	Test for giv-setting before check can_eliminate_biv_p.
-	New error check for replaceable giv whose value needed after loop.
-	(only_reg_use_p): New fn.
