- on systems w/o floating point.
- (TARGET_FLAGS): -mdebugf suppresses filling load delay slots.

- C++ that I'm aware of, but are defined in common code, so they
- should be displayed here.
-
- * cplus-parse.y (template_def): Separate set of derivations, for
- class and function templates. Template_def is a type of extdef;
- extern_lang_string before template_def is not permitted.
- (fn_tmpl_end): New nonterminal, anything that signals the end of
- the portion of a template that we should parse.
- (yyprint): Define only if YYDEBUG. Handle TYPESPEC.
- (datadef): Complain at class template override declaration if that
- specialization has already been produced by expansion. Template
- definitions no longer belong here.

- whether or not to go through with it.
- (template_instantiation): Put decl in global scope only if not
- already there.

- (processing_template_{decl,defn}): New variables.
- (push_template_decls, pop_template_decls): Accept parmlist and
- arglist as separate arguments, instead of deriving both from the

- making it transparent to tags. Removed some pointless checks from
- pop_template_decls that are only needed in push_template_decls,
- and some assertions from both. Callers changed.

- TEMPLATE_*_PARM nodes.

- Still may need extending for some tree node types.
- (do_pending_expansions): At end-of-file, expand any templates not
- yet expanded which were actually needed. Needs work to accomodate
- latest specs.
- (process_template_parm): Simplified slightly. Non-type parms
- should be marked read-only; aggregate types are not allowed, since
- equality checks don't work.
- (end_template_parm_list): Moved to after process_template_parm.
- Push a level, and push decls for TEMPLATE_*_PARMs. Set
- processing_template_decl flag.
- (end_template_decl): For non-class templates, build a
- TEMPLATE_DECL and store the regular decl in its result field.
- Context and other values get copied over too. Call poplevel to
- get rid of the TEMPLATE_*_PARM decls, and call
- dont_forget_overload to avoid losing the declaration later. Clear
- processing_template_decl flag. Call get_pending_sizes, so later
- function compilation doesn't try to evaluate sizes of templates.
- (mangle_class_name_for_template): Convert type/non-type check from
- switch to if test. Added support for ENUMERAL_TYPE, REAL_TYPE,
- and POINTER_TYPE parms.
- (instantiate_class_template): Renamed from old
- instantiate_template. Don't expand if type size is set, or if
- being-defined flag is set, or use-template flag is non-zero. If
- other-template parms are used in the parm list, construct a simple
- RECORD_TYPE node and return it. Catch case of template declared
- but not defined before use. Renamed argument from class to
- classname. Set processing_template_defn flag.
- (instantiate_template): New routine; constructs new decl node
- given TEMPLATE_DECL node and template arg vector.
- (end_template_instantiation): Set use-template field to 2 ("did
- use template"). Clear processing_template_defn flag.
- (reinit_parse_for_template): Get template-info ptr from decl node.
- Store template parm vector in it.
- (pending_template_expansions): List of templates that may need
- expanding later for function or class data definitions.
-
- * cplus-method.c (build_overload_value): Ensure tree code is
- PARM_DECL. Handle ENUMERAL_TYPE like INTEGER_TYPE. For DImode
- values, compare against integer_zero_node instead of constructing
- another one. Added support for POINTER_TYPEs. If not
- REAL_IS_NOT_DOUBLE, support real values as well.
- (build_overload_name): Accept TEMPLATE_*_PARM nodes, but generate
- a string that should cause some assembler errors.
-
- * cplus-ptree.c (print_lang_decl): Retrieve template-info from its
- new place.
- (print_lang_type): For TEMPLATE_TYPE_PARM, print its (short) info
- and return. For RECORD_TYPE, print use-template and interface-*
- fields.

- should be associated with the template body, not with the class.
- Do overload the template name, however.
- (pop_class_decls): Don't call pop_template_decls.
-
- * cplus-call.c (build_method_call): Changed to recognize
- constructor of template class.
- (build_overload_call): Add in number of template substitutions as
- extra cost of a candidate function. For template decls, try
- unification and instantiation before evaluating cost of result.
- This too is incorrect in terms of the spec, but it's a starting
- point for later work.
-
- * cplus-class.c (finish_struct): If structure is named, undo
- overload of its name as a template.
- (pushclass): If prev_class_type was a template class, pop it; the
- decls are handled wrong and should be re-entered.
-
- * cplus-decl.c (poplevel): Assert that the current level is not
- global.
- (push_to_top_level): Include global scope when looking for old
- values, because class bindings aren't listed in any other one
- place.
- (push_overloaded_decl_top_level): New function; like
- push_overloaded_decl, but places decl in global binding level.
- (dont_forget_overload): New function; removes decl from list of
- overloads to be forgotten when scope is exited.
- (start_decl): If template parms are used, construct a
- TEMPLATE_DECL node referencing the current decl. For function
- templates, call push_overloaded_decl; for class template members,
- chain them into the class template definition.
- (grokdeclarator): Don't try determining size of a
- TEMPLATE_CONST_PARM node. For template class-data decls,
- construct a phony VAR_DECL node and return it.
-
- * cplus-decl2.c (grokfield): For static class data, use
- build_overload_name result, instead of copying class name, since
- the latter could be a human-readable template class name. (If
- NEW_OVERLOAD_SCHEME is not defined, do this only if the class has
- a template-derived name.)

- pending_inlines pointer back in PRE_PARSED_FUNCTION_DECL instead
- of next.
- (process_next_inline): Ditto. Pop pending inline data if needed.
- (store_pending_inline): New function. Decides which obstack to
- store a pending definition on, and which list to chain it into.
- (reinit_parse_for_method): Call it.
- (reinit_parse_for_block): If character passed in is '=', look for
- a semicolon to end the block; don't require a {} block. Don't pad
- to 8 bytes on USG, since we aren't feeding input via stdio any
- more. Also, use newlines instead of # directives for advancing
- line number only a few lines.
- (cons_up_default_function): Punt padding for USG stdio, since we
- aren't using it any more. Use default_def for definition. Call
- store_pending_inline to save it away.
- (identifier_type): For TEMPLATE_DECL, DECL_RESULT field non-null
- indicates a non-type template, so don't return PTYPENAME.
- (yylex): If end-of-file and input isn't redirected, call
- do_pending_expansions and maybe start yylex over. Don't check
- TEMPLATE_EXPANSION_NAME_P; a proper name transformation system
- will eliminate conflicts. Try for SCOPED_TYPENAME with PTYPENAME
- too.

- set only the condition code and that set both the condition code
- and a normal result.
- Delete "cc" attribute and add "type" attribute.
- Define delays for cc-setting insns and for loads.
- Replace `d' constraint with `r'.
- Delete patterns for HImode and QImode arithmetic operations.

- `expand_inline_function', also catch the case where the base
- register is VIRTUAL_STACK_VARS_RTX.
- (simplify_binary_operation): In EQ and NE case, convert a COMPARE
- operand to something we can optimize.
- (refers_to_mem_p): Handle the case when `base' is a LO_SUM.
- * integrate.c (FIXED_BASE_PLUS_P): Define this to recognize offsets
- from the various virtual registers.
- (expand_inline_function): Expand exprs using EXPAND_SUM so as to get
- stack frame addresses instead of pseudos. This yields much better
- cse (at little cost) for GNU C++. Also, test FIXED_BASE_PLUS_P as
- an alternative to CONSTANT_P to record a known register value.
- * jump.c (find_cross_jump): If we are processing a cross jump and
- the insns fail to match, try looking for a REG_EQUAL note that makes
- them equivalent insns. If found, keep going. This is important for
- merging cleanup codes when one cleanup path gets frame address in a
- register when the other path gets the frame address explicitly.
-
- * cplus-init.c (build_delete): Fixed residual use of 1-based
- indexing to use 0-based indexing instead.

- for exprs which are FIXED_TYPE_P.

-
- * cplus-decl.c (maybe_build_cleanup): Add LOOKUP_NONVIRTUAL to flags
- argument in call to `build_delete' if DECL does not use virtual
- baseclasses. If it does, we go through a function call to save
- space, unless FLAG_EXPENSIVEO_OPTIMIZATIONS is nonzero. ??Better
- approach is to know, in expand_cleanups, to clear `flag_no_inline'
- during the cleanup's expansion.
-
- * cplus-*.c (various places): Add LOOKUP_DESTRUCTOR to all places
- where we know we are calling a destructor for a non-null object.
-
- * stmt.c (fixup_gotos): Run destructors on cleanups that come
- from the block being exited, in addition to any inner blocks
- for which LABEL is now defined.
- (expand_return): Take care of destructors that occur in the
- current binding level.
- (fixup_cleanups): If we emitted no insns, don't change *BEFORE_JUMP.
-
- * rtlanal.c: Define `target_flags' here...
- * toplev.c: ...not here. This enables us to link gen* programs
- which might, through rtlanal.o, pull in references to `target_flags'
- that are never used.
-
- * function.c: Add declaration for `current_function_uses_const_pool'.
- * expr.h: Add extern declaration for that variable.
- * function.h (struct function): Add a slot named
- `uses_const_pool' for `current_function_uses_const_pool'.
- * function.c ({push,pop}_function_context): save and restore the
- value of `current_function_uses_const_pool'.
- * rtl.h (FUNCTION_FLAGS_USES_CONST_POOL): Defined to be 0200.
- * integrate.c (initialize_for_inline):
- FUNCTION_FLAGS_USES_CONST_POOL now contributes to the value of
- `function_flags'.
- (output_inline_function): Restore `current_function_uses_const_pool'
- from `function_flags'.
- (save_for_inline_copying): Only call `save_constants' if
- `current_function_uses_const_pool' is nonzero.
- (save_for_inline_nocopy): Ditto.
- (save_constants): Tweaked to perform its treewalk faster. Notably,
- it no longer accepts ptrs to NULL rtl. All callers changed.
- * varasm.c (force_const_mem): Set `current_function_uses_const_pool'
- if we create a constant pool reference.
-
- * cplus-parse.y, c-parse.y: Add new function `set_yydebug'. If
- YYDEBUG is defined, sets `yydebug' to VALUE. Otherwise, prints
- warning that operation is invalid.
- * toplev.c (main): Call `set_yydebug' instead of setting `yydebug'
- directly. This allows user to turn YYDEBUG off for faster parsing.
-
- * cse.c (simplify_binary_operation): Eliminate abort when passed
- DImode operands.

- (reload): Compute separate basic_block_needs for each class.
- (spill_hard_reg): If pseudo is only in one block, see if that block

- (reload_reg_class_lower): Use them.
- (allocate_reload_reg): New function.
- (choose_reload_regs): Track size and class of any groups. We
- can inherit reloads if we are the size of the largest group or
- if our class is disjoint from those needed for groups.

- unless there is a later reload with a smaller class; call
- allocate_reload_reg to do the actual allocation.
- Use new vars above.
- (emit_reload_insns): Delete output reload even if we weren't
- storing to memory.
-
- * reload.h (reload_secondary_reload, reload_secondary_p): New vars.

- REG_UNUSED note added.
- (update_links): Ignore REG_EQUIV and REG_EQUAL notes on insns that
- have more than one set. Generalize flow analysis of the sets in
- the new insns so that it can handle new insns which have multiple

- REG_UNUSED note for (cc0) is present on INSN, return 1.

- to out_operand to avoid conflict with output_operand in final.c.
- * a29k.md: Likewise.

-
- * unroll.c (final_giv_value): Use expand_binop instead of
- gen_sub2_insn when emitting subtract insns, since expand_binop
- will work for any operands.
-
- * sched.c (schedule_insns): Don't split no-op moves; doing so
- breaks the code that handles REG_NO_CONFLICT blocks.
- (update_links): Delete the code that prints a warning for
- REG_EQUAL notes where the original dest can't be found. This no
- longer occurs because of the above change.
-
- * sched.c: Generalize memory aliasing code so that it will work on
- non-RISC machines. Instead of saving just the insn on the pending
- lists, now saves both the insn and the mem rtx. Old variables
- pending_read and pending_write replaced with pending_read_insns,
- pending_read_mems, pending_write_insns, and pending_write_mems.
- (read_dependence, true_dependence, anti_dependence,
- output_dependence): Now passed a MEM rtx instead of a PATtern.
- (add_insn_mem_dependence): New function. Adds an insn and a mem
- to a pending list pair.
- (sched_analyze_1, sched_analyze_2, sched_analyze): Modified to use
- new pending list scheme.
- (schedule_block): Likewise.
- (schedule_insns): Likewise.

- in the current directory, not $(srcdir)
- (install-headers): Use basename to strip off $(srcdir) from
- include files when installing and changing mode.

- the second.
- (load_multiple): Fix typo in operand number and add newline.
-
- * reload.c (find_reloads_address_1): Pass actual location of a
- MEM used in an address; also handle the case when the MEM was
- copied. Ensure we reload the copy, not the original address.
-
- * reload1.c (eliminate_regs, case {INSN,EXPR}_LIST): Correctly handle
- the cases when one or more operations is (nil).
-
- * local-alloc.c (block_alloc): Check for REG_EQUAL on list insn
- of REG_NO_CLOBBER sequence, not first.
- (no_conflict_p): Set LAST and use INSN instead of P for loop start.

-
- * loop.c (strength_reduce): Don't emit an insn after loop_end to
- set the final value of a reversed biv. There is already an insn
- there setting the biv's proper final value.

-
- * gnulib1.c (various functions): Added declaration of INTIFY to

-
- * reload.c (find_reloads): Like prev change here, for optional reloads.
-
- * tm-sparc.h (FUNCTION_BLOCK_PROFILER): Must set %o0 to the address
- LPBX0 by adding in the low part of the address before calling
- ___bb_init_func.
-
- * tm-next.h (ASM_OUTPUT_CONSTRUCTOR, ASM_OUTPUT_DESTRUCTOR):
- New macros. Place reference to constructor or destructor into
- constructor or destructor section.
-
- * tm-next.h (EXTRA_SECTIONS, EXTRA_SECTION_FUNCTIONS): Add
- new constructor and destructor sections.
-
- * jump.c (squeeze_block_notes,squeeze_notes): Chage the name of
- squeeze_block_notes to squeeze_notes. Also handle LOOP_BEG, LOOP_CONT
- and LOOP_END notes, since these must remain in their original order.

-
- * m68k.md (dbra patterns): Use `=' in constraint of op 0.

-
-Fri Apr 12 00:57:48 1991 Jim Wilson (wilson at cygnus.com)
-
- * sched.c: Update all comments to reflect source changes.
- Make old_live_regs a static global, instead of local to schedule_block.
- Schedule_block is now void, since its return value was always 1.
- Rename last_function_call_not_const to last_pending_memory flush.
- This can not be a CALL_INSN or a INSN that writes memory.
- New variable pending_lists_length so that the lists can be flushed
- when they get too long.
- Use GET_RTX_CLASS instead of multiple GET_CODE calls whenever it
- makes sense.
- (read_dependence): New Function. Returns one if two reads are
- dependent. This can happen if both are volatile reads.
- (true_dependence, anti_dependence, output_dependence): Two volatile
- memory access are always dependent.
- (order_calls): Function deleted. It was very short, it was only called
- once, and it no longer did what its name implied. Its one call was
- replaced with the body of the function.
- (sched_analyze_1): Correctly handle stripping of SUBREGs, etc from
- the set dest.
- If the pending lists are longer than 32 when processing a memory
- write, then make this write depend on all previous and all future
- memory accesses so we can flush the pending list. This is necessary
- because the algorithms used are O(N*N).
- (sched_analyze_2): For memory reads, check whether it is read
- dependent on any previous memory read (this can happen if both reads
- are volatile).
- (sched_analyze_insn): Replace call to order_calls with the body of
- that function.
- (sched_analyze): Don't clear last_memory_pending_flush for a non-const
- call, since any future call must still depend on all previous memory
- accesses.
- (sched_note_set): Correct handling of SUBREGs, etc. For partial sets
- of a register, must treat this exactly the same way as flow.c, i.e.
- a partial set of a register does not kill the register. Delete
- ifdefed out code which is obsolete.
- (attach_deaths): New argument SET_P, which indicates whether this is
- a set (if true) or a use (if false) of the rtx X. Correct handling
- of REG_DEAD notes, to account for the new REG_UNUSED note.
- (attach_deaths_insn): Pass new additional parameter to attach_deaths.
- Always call attach_deaths for sets within a parallel. Call
- attach_deaths for clobbers.
- (new_sometimes_live): Ifdef out code which should never be executed,
- and replaced with call to abort.
- (schedule_block): Now void.
- When processing block to find dead_regs, don't unlink REG_UNUSED notes,
- but must mark the indicated register as dead.
- (update_links): Completely rewritten to make more general. Now handles
- all REG_NOTEs except REG_INC and REG_LABEL. No longer makes simple
- assumptions about the form of instructions. New argument orig_insn,
- which is the original unsplit insn.
- (schedule_insns): Delete unused volatilep code. Pass new parameter
- to update_links.

- (GO_IF_LEGITIMATE_ADDRESS): Distinguish the -mbig-pic case.
- * m88k.md (SImode hi16/lo16): Use %g for -mbig-pic.
-
-Wed Apr 10 21:53:32 1991 Jim Wilson (wilson at cygnus.com)
-
- * unroll.c: Change global variable declarations to static.
- Four new global variables loop_iteration_var, loop_initial_value,
- loop_increment, and loop_final_value, used for communication between
- loop_iterations and precondition_loop_p.
- (unroll_loop): Before deleteing the insns in the original loop body,
- emit a label after the last insn to be deleted, to ensure that no
- delete_insn call will delete past that point.
- (precondition_loop_p): Use global loop_* variables setup by
- loop_iterations, instead of trying to calculate their values again.
- (copy_loop_body): Don't emit copies of the start_label.
- (approx_final_value): COMPARISON argument now passed as the pair
- COMPARISON_CODE and COMPARISON_VALUE.
- (find_splittable_regs): When completely unrolling a loop, and the
- initial value of a biv is a hard register or itself, then must
- create a new register to hold its initial value for splitting.
- (loop_iterations): Set the new global variables loop_*.
- If the comparison value is an invariant register, then search the insns
- before the loop to try to find a constant value for the register.
-
-Wed Apr 10 16:02:16 1991 Tom Wood (wood at dg-rtp.dg.com)
-
- * out-m88k.c (pic_addressing_base_rtx): A pseudo register coined

- implement PIC.
- (output_call): Use the #plt form when doing PIC.
- (m88k_layout_frame): The addressing base register is no longer
- fixed and r1 need not be saved for PIC.
- (output_prologue): Output instructions to setup the addressing
- base register if one is needed.
- (print_operand_address): Support the PIC case.
- * m88k.md (most patterns using hi16/lo16): Disable these for PIC.

- use the bison -l option to allow debugging in c-parse.tab.c.
-
- * From kenner@vlsi1.ultra.nyu.edu.
- * out-m88k.c: Include insn-config.h before conditions.h, which

-
- * expmed.c (expand_divmod): Convert OP1 to COMPUTE_MODE when we
- convert OP0.
-
- * combine.c (subst): Use gen_binary.
- (simplify_comparison): If we have a ZERO_EXTRACT from a constant

- location of bit in constant; this simplifies ((1 << x) & 1) == 0.
-
- * combine.c (gen_lowpart_for_combine): Copy code for CONST_DOUBLE
- from gen_lowpart instead of calling it; it will abort for certain
- floating-point cases, while we will just surround the object with
- a SUBREG.
-
-Thu Apr 4 22:31:36 1991 Jim Wilson (wilson at cygnus.com)
-
- * unroll.c (new file): Implements loop unrolling. Completely
- unrolls small constant bounded loops. Unrolls other constant
- bounded loops by an amount modulo the number of iterations so that
- only one exit test is needed. Preconditions loops whose iteration
- count can be calculated at run time, so that only one exit test
- is needed. Can also unroll any other loop by having multiple
- copies of the exit tests. Tries to simplify addresses while
- unrolling.
-
- * tree.def: BLOCK trees have 4 fields, not 5.
-
- * toplev.c: Add new flag -dt to dump RTL after the second cse pass.
- Define two new flags, flag_unroll_loops and flag_unroll_all_loops,

- between BLOCK trees and loops. This info is needed when doing both
- loop unrolling and outputting debugger info.

- trees corresponding the loop indicated by LOOP_NUMBER, so that the
- BLOCK notes inside the loop will still match the BLOCK trees for
- the loop.

- "decrement_and_branch_until_zero". Add macros to access new
- field of inline_header rtx, which holds a pointer to the function's

- * rtl.def: New entry for inline_header to hold a pointer to the
- function's original DECL_INITIAL tree.
-
- * loop.h (new file): Move many declarations from loop.c to the new

- always failed.
- (prescan_loop): Delete obsolete code.
- (find_and_verify_loops): Add code to initialize

- (mark_loop_jump): Add code for keep chain of loop_number_exit_labels
- for each loop.
- (invariant_p): LABEL_REFs are not invariant when doing loop unrolling.
- Remove static from definition, so that it can be called from unroll.c.
- (strength_reduce): Change name of variable maybe_never to
- not_every_iteration, to help emphasize that it is not the same
- as the variable maybe_never in the code motion code. Modify code
- that computes its value so that it will be false more often, resulting
- in better code.
- (strength_reduce): Added code to call the new loop unrolling
- functions, e.g. unroll_loop, loop_iterations, etc.
- (strength_reduce): New code to handle biv's and giv's which must
- be set to their final_value after the loop exits.
- (strength_reduce): Reversed giv's and biv's must have their values
- calculated differently. Add new field reversed to struct induction,
- and code to check and use its value.

- that have a decrement_and_branch_until_zero instruction.
- (find_mem_givs): New argument loop_start.
- (record_giv): New argument loop_start.
- The always_computable field for DEST_ADDR givs is always set true.
- New code to check for case of spaghetti code, in which case the
- giv can never be considered replaceable.
- (check_final_value): New function. For givs which are not otherwise
- replaceable, try to calculate their final value, and then try
- to use this to make them replaceable.
- (update_giv_derive): Skip inner loop if giv is known to be underivable
- at the beginning. Must set cant_derive if we pass an insn that
- modifies the giv's biv, and we can't calculate an adjustment.
- (emit_iv_add_mult): Remove static definition so that it is callable
- from unroll.c.
- (check_dbra_loop): Reversed biv's must be marked as such, so that
- they can be treated specially in the rest of loop.c.
- (final_biv_value): Moved to unroll.c, alongside the new function
- final_giv_value. Extensively rewritten to work for most common
- cases.
- (update_reg_last_use): Verify that insns have a valid luid before
- trying to use it. Don't perform any action if no value luid.
- (get_condition): Correct initial comment.
- (get_condition_for_loop): Remove static definition so it is callable
- from unroll.c.
-
- * integrate.h: Replace `tree' use in definition with
- `union tree_node *' so that tree.h does not have to be included when
- this file is included.
-
- * integrate.c (initialize_for_inline): Pass additional argument,
- the DECL_INITIAL (fndecl) tree, to gen_inline_header_rtx. Update
- and correct comment.
- (save_for_inline_copying): Copy the decl tree, so that virtual reg
- instantiation, and loop unrolling, won't affect the saved tree.
- (copy_decl_tree): New argument, functionbody, which distinguished
- between calls from save_for_inline_copying and calls from
- expand_inline_function.
- (copy_rtx_and_substitute): Return orig instead of aborting when
- inline_target is zero so that loop unrolling can use this code.
-
- * gcc.texinfo: Document the new optimization flags -funroll-loops
- and -funroll-all-loops, the new dump option -dt, and the new named
- pattern "decrement_and_branch_until_zero".

- flag_unroll_all_loops.
-
- * emit-rtl.c (gen_inline_header_rtx): New argument
- original_decl_initial. Pass to gen_rtx call.
-

-
- * Makefile.in: Add source file unroll.c and header file loop.h to
- the cc1 dependencies. Add *.cse2 to the list of files deleted by

- doesn't work, return 0.
- (redirect_exp): Now static.
- * expr.c (do_jump_for_compare): Call invert_jump to invert jump
- to false label after emitting jump; if this fails, convert to

- Insn numbers start at 1 and we have two entries in regs_live_at
- for each insn.
- Search for REG_NO_CONFLICT block when we see a CLOBBER insn; this
- avoids having already seen sets to the output register.
- Call wipe_dead_reg for anything in a REG_UNUSED note.
- Delete references to reg_first_use.

- Never tie pseudos if SREG already has a quantity assigned.
- When updating size, use reg_next_in_qty instead of looping over

- instead of divsll/divull.
-
- * integrate.c (expand_inline_function): Remove change of March 20th.
- Instead, expand args in two passes. First, expand all that go
- into registers. Then do those in memory with store_expr.

-
- * alliant.md: Eliminate unneeded patterns: HImode zero_extract,
- (set (cc0 (subreg ...))), (set (cc0) (and ...)),
- (and (zero_extend ...) ...), shift right of 24 and 16.
- Use alternatives to select assembler template when possible.
- Use const_int_operand instead of immediate_operand when
- possible to avoid explicit test for CONST_INT.
- Write add-and-branch patterns with PLUS removed, the way combine
- produces them.
-
- * rtlanal.c (refers_to_regno_p): If X is a SUBREG of a hard
- register, treat it as if it were the appropriate register.
- CLOBBER doesn't refer to anything.

-
- * toplev.c (do_abort): New function, just calls abort.
- (main): Set lang_expand_expr to address of do_abort; abort might be
- a macro that is more than just a function name.
-
- * cse.c: (qty_... variables): Refined to be undefined for indices
- less than MAX_REG. Thus, we need not intialize them at the start
- of a basic block and can instead inialize a quantity as we create it.
- (reg_{next,prev}_eqv): These variables will now be defined only when
- reg_qty[N] != N and hence need not be initialized every block either.
- (new_basic_block): Need not initialize reg_rtx for new block; the
- only time we can inherit values from previous blocks is for hard
- regs and it doesn't matter in that case.

- Cast alloca to (char *).
-
- * out-romp.c (update_cc): cc_status.value[12] can also be a COMPARE,
- so use reg_overlap_mentioned_p to see if an insn that modifies a
- register invalidates cc0.
-
- * reorg.c (link_cc0_insns): If next insn is a SEQUENCE, the insn
- using cc0 is the first insn in the sequence.
- (mark_target_live_regs): Don't assume that a REG_DEAD note always
- refers to a register.

-
- * reload1.c (reload_reg_free_before_p):
- An input reload is use before an output or output address reload.
-
- * genoutput.c (validate_insn_alternatives): New function.
- Loop over insn's alternatives to find out how many
- alternatives the insn pattern is to support. Verify that if
- any alternatives are specified for a given operand that the
- number of alternatives match the numer of alternatives for
- this insn.
- (gen_{insn,peephole,expand,split}): Call
- `validate_insn_alternatives' after scanning the insn. This
- sets up the value N_ALTERNATIVES for the insn so that
- `process_template' can check that the number of alternitves
- given matches the number of asm choices for `@' constructs.

+ * fixinc/fixfixes.c (machine_name_fix): Don't free 'scratch'.
- * dbxout.c (toplevel, dbxout_init): Instead of always using `Ltext'
- as the label at the beginning of the text region, properly localize
- it, so that machines which do not put leading underscores in front
- of external names do not have a problem if the user uses `Ltext'.
- (dbxout_init): Call text_section before putting out localized
- `Ltext', in case ASM_FILE_START put us into a different section.

-
- * out-romp.c (update_cc, case CC_COMPARE): Call CC_STATUS_INIT.
- * romp.md: In pattern that sets cc0 and copies a register to another
- register, allow the output to be in memory so that we don't get an
- output reload, which will cause problems.
-
- * varasm.c (assemble_variable): Ensure DECL_INITIAL is non-zero

- done elsewhere.

- Add cases involving logical and arithmetic operations applied
- to comparison operators or values with only one significant bit.

- can be done with ABS.
- Avoid generating (const (const ...) ...).
