-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.
