+	OLDEQUIV (a register that holds the same value).
+
+	* tm-m68k.h (LEGITIMIZE_ADDRESS): Don't give force_operand a target.
+	This can cause the use of multiple insns with same output reg,

+
+	* cse.c (canon_reg): Rewrite for speed; use a switch.
+	(cse_insn): Don't call find_reg_note if REG_NOTES is 0.
+
+	* cse.c (cse_insn): Store modified SET_SRC even if there's a REG_EQUIV.
+	Inhibition was needed when the SET_SRC was the only place to find the
+	equivalent value; now it is in the REG_EQUIV note.
+
+	* stmt.c (expand_asm_operands): If NINPUTS is 0, make vec of no elts.
+	* regclass.c (reg_scan_mark_refs): Don't lose if XVEC (x,i) is 0.

+	* expr.c (clear_pending_stack_adjust): Really do clear it,
+	if current fcn doesn't want to be inline.
+
+	* cse.c (cse_insn): Speedup: instead of safe_hash, use canon_hash

+	* cse.c (cse_insn): Ignore a REG_EQUIV or REG_EQUAL note if the
+	equivalent value is the same as the SET_SRC of the insn.

+	just assume value is 1.
+	(propagate_block): Don't call mark_{used,set}_regs for a stack-pop
+	since if it isn't dead it has no effect on any useful life data.
+	(mark_set_1): Return quickly if setting stack-ptr, and almost as

+	in integer case (they were for casting a pointer).

+	* parse.y (compstmt_or_error): Parse a compstmt after ignoring error.
+	Use this for fctn body so that an error after store_parm_decls
+	won't recover to xdecls and call store_parm_decls again.
+	Typical cause was missing semi at end of last parmdecl.
+
+	* parse.y: Add missing semicolons in actions.
+	(yylex): Don't use yylloc.
+
+Sun Jun  5 16:14:40 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)
+
+	* typecheck.c (build_array_ref): Check arg types here, to make

+	* expmed.c (store_fixed_bit_field): Avoid shifting by 32.
+	* cse.c (fold_rtx):
+	* symout.c (subrange_p):  likewise.
+
+	* local-alloc.c (block_alloc): If operands 1 and 2 commute,
+	try tying output to operand 2 if operand 1 won't do.
+
+	* toplev.c (compile_file): Pass main_input_file to symout_init.
+
+	* tree.c (build_real, build_real_from_int_cst):
+	Call CHECK_FLOAT_VALUE if it's defined, to report out-of-range values.
+
+	* tree.c (build_real, build_real_from_int_cst): New 1st arg TYPE.
+	* parse.y (yylex): Pass this arg; requires parsing suffixes first.
+	* fold-const.c (fold, combine, fold_convert): Pass this arg.
+	Handling of float binops in `combine' simplified.
+
+	* tm-encore.h (CPP_PREDEFINES): Remove -Dencore since CC lacks it.
+
+	* final.c (output_source_line): Let ASM_OUTPUT_SOURCE_LINE
+	be used for SDB also.
+
+Mon May 30 00:21:15 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)

+
+	* decl.c (finish_decl): Error in test for zero-size array warning.
+
+	* reload.c (find_equiv_reg): New arg MODE specifies mode in which
+	an equivalent value is needed.  Equivalence must be good in that mode.
+	In addition, notice overlap with multiword register modes.
+	Simplify, knowing that registers have already been renumbered.
+	It was invalidating memory-goals too easily; setting a reg
+	only invalidates memory-goal if its address varies.
+	* reload.c, reload1.c, jump.c: Calls pass the new argument.
+
+	* cccp.c: For correct ANSI, must reject `$' in identifiers.
+	(dollars_in_ident): Variable says whether to allow them.

+	(rescan, do_define): Delete former pedantic warnings for `$'.
+	(initialize_char_syntax, initialize_builtins): Inits split to two
+	functions; former is called after options are scanned
+	so `$' is in is_idchar conditionally.
+	* gcc.c: For -ansi, pass -$ to cccp.
+	* toplev.c, flags.h: Define dollars_in_ident.
+	* parse.y (yylex): Treat $ as punctuation unless dollars_in_ident.

+
+	* cccp.c (rescan): Preprocessing numbers can have signs, after `e'.
+
+	* integrate.c (expand_inline_function): Abort, don't return failure,

+	* regclass.c (reg_class_record): Ignore `&' in constraint.
+
+Sun May 29 00:20:23 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)
+
+	* Makefile: Run ranlib only if /usr/bin/ranlib exists.
+	Add comment saying what to do on system V.
+
+	* tree.c (suspend_momentary): Switch to the saveable_obstack
+	for the sake of inline functions.
+
+	* flags.h (enum debugger): New enum for write_symbols.
+	* toplev.c, varasm.c, final.c: Use the enum constants where appro.
+	Add calls to sdbout paralleling the calls to dbxout;
+	put each in the appropriate conditional {SDB,DBX}_DEBUGGING_INFO.
+
+	* toplev.c (main): Delete -noreg option; it's now the default.
+	Make -O an alias for -opt.  Rename -g to -gg.  -g is alias for -G.
+	Accept and ignore -Wtrigraphs.
+	* gcc.c: Simplify the specs.
+
+	* toplev.c (compile_file), tm-*.h:
+	ASM_FILE_START is now a statement, not just a string to be output.
+	Output it *after* determining the real source file name.
+
+	* fold-const.c (fold): Simplify x >= CST to x > CST-1 (CST positive).
+	To simplify this, canonicalize relationals to put constat last.

+
+	* reload1.c (reload): Don't complain if two different but tieable
+	modes require groups of the same regclass (assuming same size group).
+
+	* cccp.c: Add 3rd arg to all `open' calls.
+
+	* parse.y (check_newline): Typo prevented ignoring whitespace.

+
+	* emit-rtl.c (gen_sequence): If LEN is 1, avoid looking at PATTERN
+	of something that doesn't have one.
+
+	* reload1.c (alter_frame_pointer_addresses): frame pointer can
+	occur by itself, not just inside a PLUS.
+	(reload): Call eliminate_frame_pointer before reload_as_needed.
+	Otherwise the latter can make reload insns that copy the frame ptr
+	to a data reg, but 68k can't copy sp+const to a data reg.
+
+	* decl.c (implicitly_declare): Always save the implicit decl
+	permanently.  Reuse an old one if it exists.
+	* tree.c (resume_temporary_allocation): Used after `end_temporary...'
+	to go back to temporary allocation.
+
+	* stor-layout (layout_{type,decl}): Call variable_size.
+	(variable_size): Turn a size into a SAVE_EXPR and either compute
+	it right away or put it on a list to be computed later.
+	(get_pending_sizes): Return that list and clear it out.
+	* stmt.c (expand_start_function): Tell `variable_size' to compute
+	sizes right away, and compute those saved on the list.
+	(expand_end_function): Tell it to put them on a list.
+
+Fri May 27 00:02:34 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
+
+	* dbxout.c (dbxout_symbol): For local static var, use 'V', not 'v'.
+
+	* gcc.c (main): Don't handle SIGHUP or SIGTERM if shell ignored it.
+
+	* Makefile, gcc.c: Propagate Make var `libdir' to gcc search path.
+
+	* expr.c (expand_expr): a PARM_DECL with no rtl can occur in size of
+	`a' in `foo (a,i) int i; struct {int x[i];} a;', so report an error.
+
+	* flow.c (insn_dead_p): insn that makes stack bigger is never dead.
+	* combine.c (try_combine): Don't splice out stores into stack ptr.
+
+	* reload.c (find_equiv_reg): Test given regno for OVERLAPPING_REGNO_P.

+
+	* integrate.c (save_for_inline): Clear unused slots in parmdecl_map.
+	(There may be some non-parm regs below max_parm_regno.)
+	* integrate.c (copy_for_inline): Don't crash if parmdecl_map elt is 0.
+
+	* Don't fail to output a static inline function that was referenced
+	via a local extern decl before its definition.
+	* expr.c (expand_call): If need to mark a fcn decl addressable,
+	mark the identifier addressable also.
+	* typecheck.c (mark_addressable): If marking fcn addressable,
+	mark the identifier as well.
+	* decl.c (start_function): If identifier was marked addressable,
+	propagate it to the function.
+
+	* parse.y (yylex): Check for ERANGE after atof is called.
+	(Sun doesn't report ERANGE.)
+
+	* loop.c (may_trap_p): Any floating arithmetic may trap.
+
+Wed May 25 00:03:34 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
+
+	* parse.y: Delete `noalias'.
+	(asm_operand): Don't allow this to be empty.
+	(asm_operands): Do allow this to be empty.
+
+	* reload.c (operands_match_p): Don't let REG and SUBREG match
+	if the reg isn't a hard reg.
+	No longer nec. to check reg_renumber, now that reload
+	substitutes the hard regno.
+
+	* reload1.c (reload): Counting existing spilled groups,
+	check HARD_REGNO_MODE_OK so we don't get fooled by an odd-even pair.
+	Spill entire need for new groups before spilling any solitary regs.
+	Reg already counted against max_nongroups can't become part of a group.
+	(new_spill_reg): Do bookkeeping associated with a new spill-reg.
+	(n_spills): This var is now static, no longer passed as arg
+	within the file.
+
+	(reload_reg_class_lower): Handle all group-reloads before solitaries.
+	(choose_reload_targets): therefore #if 0 the special code for
+	finding solitary registers that aren't suitable for groups.
+	But fix two bugs in it: braino deciding whether a reload
+	is looking for 1 register (not a group).  Use CLASS_MAX_NREGS.
+	Also braino deciding whether a spill reg can be in a group.
+	Did not fix bug that it fails to test HARD_REGNO_MODE_OK,
+	so it might split up an even-odd pair.
+
+	* vax.md: Special patterns for 8 and 16-bit fields, to make
+	move-insns (like the ones for the 68k).
+
+	* tree.c (convert_to_integer): Pass truncation down thru COND_EXPR
+	as through a binary operator.
+
+	* typecheck.c (build_cond_expr): If unpromoted operand types match,
+	don't promote them--let containing expression promote (just once).

+
+	* gnulib.c: Allow config to override INTIFY.

+	prevent inheritance of certain reloads.
+

+
+	* fold-const.c (combine): Typo in MIN_EXPR, MAX_EXPR.
+
+	* reload1.c (reload): Was counting insn_groups as total size of groups,
+	not number of groups.
+	A new spilled group counts against group-needs of superclasses.
+
+	* parse.y (parmlist{,_or_identifiers}_1): In error case,
+	return a tree list just as in the other cases.
+
+Fri May 20 02:14:51 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
+
+	* config-vax.h, config-m68k.h: If __GNUC__, use builtin-alloca.

+	* genpeep.c (match_rtx): Generated code was testing the wrong rtx
+	when testing an int or string at a nonzero index in the rtx.
+
+	* reload.c (find_reloads): Typo checking `modified' for conflict

+
+Thu May 19 13:01:01 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
+
+	* flow.c (propagate_block): Skipping back across libcall didn't happen
+	due to failing to set PREV.
+
+	* expr.c (emit_library_call): Code to increment and decrement
+	current_args_size broke since emit_call_1 was changed to restore it.
+
+	* combine.c (try_combine): When i1 or i2 auto-incs a reg, don't combine
+	if i3 uses that reg.

+
+	* integrate.c: Don't include strings.h--no need.
+
+	* stmt.c (expand_asm_operands): Don't make zero-length vectors.
+
+	* loop.c (scan_loop): After a fcn call, maybe-trap insns can't move.
+	The fcn call might exit and that would prevent the trap.
+
+	* reload1.c (reload): Set reload_first_uid to next uid to be used.
+	* reload.c (find_equiv_reg): Use reload_first_uid to ignore insns
+	that are due to reloading--only if reload_reg_p is not 0 or 1.

+	Don't allow nonexplicit constants in lprd, multiply or truncate insns.
+	Use reg_or_mem_operand for constraint in op1 of divide insns;
+	a constant there causes regclass to screw up.
+	Split alternative constraints on the bit-field insns to avoid
+	out-of-range operands in exts, inss.  Some cases of extraction
+	can be done faster via memory.
+
+	* flow.c (mark_set_1): When adding a REG_DEAD note, inc reg_n_deaths.
+
+	* dbxout.c (dbxout_type_def): Do nothing for {integer,char}_type_node.

+	class of any reg tied to the qty.
+	(reg_class_subset_p, reg_meets_class_p, update_qty_class):
+	New subroutines to implement this.
+	(local_alloc): Init reg_qty to -1 for pseudos not in cur. basic block.

+
+	* jump.c (rtx_renumbered_equal_p): Insist that modes of REGs match.

+	Use `emit_call_insn' when appropriate.
+	(gen_exp): Handle rtx's that contain strings.
+
+	* final.c, symout.c: If not NO_DBX_FORMAT, include stab.h to get the
+	N_... symbols.  Use their default definitions only if they're undef.
+
+	* expr.c (expand_call) [no PUSH_ROUNDING]: Always set argblock
+	if there are any stack-passed arguments.
+
+	* typecheck.c (build_unary_op): Mark all increment-exprs volatile.
+
+	* recog.c (reg_renumbered_fits_class_p): Delete private copy of
+	reg_class_contents.
+
+	* reload1.c (forget_old_reloads): Handle PARALLEL case by recursion.
+	Explicit store into a spilled reg invalidates old reloaded contents;
+	this can occur when we drop through into a basic block whose need was 0
+	(and so whose local pseudos were not spilled).

+	where get_narrower makes no change.
+	(build_binary_op_nodefault): Likewise for shortening shifts.
+
+	* stmt.c (expand_end_case): Use type_for_size to get the type
+	to convert the index to, since `int' is wrong if -mshort.
+
+	* decl.c (grokdeclarator): Don't check PARM type for completeness.
+	(grokparms): If fn definition, check all parm types for completeness.
+	(store_parm_decls): Likewise.

+	Also ignore it for addresses of stack slots (avoid invalid REG_EQUIVs).
+
+	* typecheck.c (digest_init): If traditional, allow `char x[100]=0;'.
+
+	* tree.c (get_unwidened): Don't alter a COMPONENT_REF if
+	innerprec equals the precision of the existing type.
+	It was changing pointers to integers.
+
+	* m68k.md (movdi): Put all fpregs in separate constraint alternatives
+	and handicap them so spill reg won't be an fp reg.
+
+	* parse.y (yyerror): Use the arg as part of the error message.
+
+	* decl.c (start_function): Give the RESULT_DECL type int rather
+	than char or short.
+	* typecheck.c (c_expand_return): Convert value from fn's return type
+	to the RESULT_DECL's type.
+
+	* Avoid generating dbx xrefs to enums, since dbx loses on them.
+	Do this by outputting all types in order of definition.
+	This is done only for top-level types; problem remains for local ones.
+
+	* decl.c (finish_decl): Do rest_of_decl_compilation for TYPE_DECLs.
+	* toplev.c (rest_of_decl_compilation): Do dbxout_symbol for them.
+
+	* dbxout.c (dbxout_symbol): Check DECL_RTL only for fns and variables.
+	For a TYPE_DECL, ignore it if the type was already output
+	and its preferred name is the TYPE_DECL.  Else output type in full.
+
+	* decl.c (pushdecl): Don't prefer typedef names to type tag names.
+
+	* stor-layout.c (chain_type): Build chain in forward order.
+
+
+	* tm-3b1.h (ASM_OUTPUT_CASE_LABEL): Error getting length of table.
+
+	* tm-3b1.h: #define SGS_3B1 was missing.
+
+	* typecheck.c (build_compound_expr): Ignore non-volatile subexprs.
+
+	* fold-const.c (fold): Simplify (unsigned) foo >= 0, etc.
+
+	* stor-layout.c (layout_type): Set TYPE_PRECISION of ptr types.
+
+Wed May  4 08:06:25 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
+
+	* parse.y: Don't use the Bison @ construct, since it makes parser slow.
+
+	* decl.c (finish_function): Delete FILENAME and LINE args.
+
+	* typecheck.c (digest_init): No pedantic warning for array="string".
+
+Tue May  3 09:09:30 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
+
+	* toplev.c (main): Ignore `-Wcomment'.
+	* gcc.c: Pass -Wall to cpp (which treats it like -Wcomment).
+
+	* tm-isi68.h: Greatly simplified; now works only with GAS.
+
+	* tm-m68k.h (EMPTY_FIELD_BOUNDARY): now 16 (right on Sun, ISI and HP).
+	* tm-sun3.h: No need to redefine it.
+
+	* decl.c (finish_struct): Don't ever make DECL_ALIGN smaller.
+
+	* decl.c: Rename min, max to MIN, MAX.
+
+	* typecheck.c (convert_for_assignment): Avoid warning if assigning
+	a `void *' from a `const void *'.
+
+	* combine.c (FAKE_EXTEND_SAFE_P): Turn off for mem refs; avoid faults.
+
+Mon May  2 07:28:27 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
+
+	* tm-vax.h: Support -mg switch to use g-float instead of d-float.
+	New macros TARGET_G_SWITCH, ASM_DOUBLE_CHAR.
+	Changes in TARGET_SWITCHES, ASM_OUTPUT_DOUBLE.
+	Define code `#' for PRINT_OPERAND.
+	* vax.md: use `#' in opcodes for doubleword float.
+
+	* tm-vax.h: Define UDIVSI3_LIBCALL and UMODSI3_LIBCALL.
+
+	* cccp.c (main, do_include): Implement -I- switch.
+
+	* jump.c (jump_optimize): When hunting NOTE_INSN_FUNCTION_END,
+	skip final RETURN (found on the vax).
+
+	* toplev.c (main): -Wall is equiv to all -W switches combined.
+
+	* stmt.c (expand_decl, expand_end_bindings,
+	expand_{start,end}_function).  The -noreg treatment of `register' vars
+	is extended to vars used as addresses of vars in memory (varying-size
+	structures).
+	(use_variable): Emit USE for regs used in specified rtx.
+
+	* cse.c (fold_cc0): Stack-frame addresses are always nonzero.
+	(fold_rtx): 0200 bit in prev_insn_cc0 means only zeroness is known.
+
+	* parse.y (parmlist): poplevel needs 3 args.
+
 Sun May  1 07:20:34 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
 
+	* decl.c (start_function): typo checking for incomplete return type.
+
+	* emit-rtl.c (restore_reg_data): If a pseudo appears nowhere,
+	don't leave its slot empty; create a pseudo for that slot.
+
 	* Version 1.21 released.
 
 	* expr.c (expand_call): Merge duplicate code for structure_value_addr.
