- seems to occur in unoptimized compilation.
- * pa.h (REGNO_OK_FOR_FP_P): Logic bug.
- * va-pa.h : When __GNUC__ == 1, don't include the gcc 1 varargs

- here. This avoids multiple typedefs of va_list.

- TARGET_SNAKE.
- (umulsidi3): New pattern.
- (reload_insi, reload_outsi, reload_indi, reload_outdi): New
- patterns. These are needed because SImode and DImode pseudoregs
- may be allocated (or reloaded) in floating point registers for
- multiplication. That means that their addresses, which were
- legitimate for SImode and DImode, aren't valid any more.

- operand to emit_move_sequence.
- (fp SImode load and store patterns): Move before main movsi

- * pa.c (emit_move_sequence): Take reload scratch register
- argument, deal with reloads of SImode and DImode mems into
- floating point registers, handle function_label_operand moves.
- (secondary_reload_class): A scratch register is needed if
- reloading a function_label_operand address (probably doesn't
- happen) or an SImode or DImode value into/out of a floating
- point register.
- * pa.h (reg_class, REG_CLASS_NAMES, REG_CLASS_CONTENTS,

- FP_OR_SNAKE_FP_REGS, used only be reload_{in,out}{si,di}.

- (movsi, movdi patterns): Remove some * constraints from fp registers.
- (pic label address pattern): Fix typo.
- (function_label_operand patterns): New patterns for loading a
- label address in HPUX 8.0.
- * pa.c (finalize_pic): No real initialization is necessary for pic.

- register. If profiling, save and restore the structure value
- return register (r28) around the call to mcount.
- (hppa_encode_label, function_label_operand): New functions.
- Record if a label is a code label so it can be treated specially
- in HPUX 8.0.
- * pa.h (TARGET_SHARED_LIBS): New flag. Generate code that can be
- linked with HPUX 8.0 shared libraries.
- (TARGET_SWITCHES): New flags: -mshared-libs and -mno-shared-libs.
- (PIC_OFFSET_TABLE_REGNUM): This is really r19. The preliminary

- (ENCODE_SECTION_INFO): Encode function labels.
- (ASM_OUTPUT_LABELREF): Deal with function labels.
- (ASM_OUTPUT_REG_PUSH, ASM_OUTPUT_REG_POP): Don't do anything for

- Major rework to have caller-saves emit load/store double insns when
- possible and to avoid useless resaving of registers restored for
- source accesses only.
- * caller-save.c (toplevel): All arrays are multi-dimensional to
- hold information for multiple save/restore insns. New variable
- hard_regs_need_restore.
- (choose_hard_reg_mode): New argument `nregs' indicating how many
- hard registers are desired. All callers changed.
- (init_caller_save): Change initialization to handle multiple
- register saves. A call-used register can not be live across
- if we can not find a single register mode to save it in.
- (multiple register saves are optional)
- (init_save_areas): Change initialization of regno_save_mem to
- handle multiple register saves.
- (setup_save_areas): Allocate space for consecutive hard registers
- in aligned consecutive memory locations. When allocating space
- for consecutive hard registers, also initialize regno_save_mem
- for each hard register stored as a single word.
- (save_call_clobbered_regs): Initialize hard_regs_need_restore.
- Set hard_regs_need_restore to hard_regs_saved after crossing
- a call. Also recompute n_regs_saved. At the end of a basic block
- we need only restore registers in hard_regs_need_restore.
- (set_reg_live, clear_reg_live): Do the right thing for
- hard_regs_need_restore and hard_regs_saved.
- (restore_referenced_regs): Just return if X is a clobber.
- Test hard_regs_need_restore to determine when to restore a hard
- register from the save area.
- (insert_save_restore): Now returns the number of extra registers
- saved/restored. New argument `maxrestore' which constrains how
- many hard registers should be restored. All callers changed.
- Do stores of consecutive registers with double store insns if
- possible. Else do them with single word insns. Likewise for
- loads, except constrained by maxrestore. Set hard_regs_saved
- and hard_regs_need_restore appropriately to minimize useless
- saves into the save area. Test against hard_regs_need_restore
- when trying to restore multiple regs and similarly test against
- hard_regs_saved when storing multiple regs.

- * mips.h (MIPS_VERSION): Set Meissner version # to 24.
- (ASM_FINAL_SPEC): Use %U to get the last file name created with
- %u, rather than %u.
- (ARG_POINTER_REGNUM): Use the hardwired register $0 as the
- argument pointer, instead of the frame pointer, to allow the frame
- pointer to be the same as the stack pointer after the initial
- stack allocations. This is to allow GCC generated code to be
- linked against MIPS shared libraries. The linker rearranges the
- code, and needs to have a frame pointer, if used, to be the same
- as the stack. The argument pointer is always eliminated in favor
- of the stack pointer or frame pointer.
- (FRAME_GROWS_DOWNWARD): Don't define this any more.
- (STARTING_FRAME_OFFSET): Locals start after the stack area to pass
- arguments to called functions.
- (STACK_DYNAMIC_OFFSET): If function is a leaf function, but calls
- __builtin_alloca, assume a default argument area, so the MIPS
- linker doesn't think a second frame pointer is created.
- (INITIAL_FRAME_POINTER_OFFSET): Don't define, since we use

- host compiler supports ANSI C.

- where it is feasible to do so, using the PROTO macro. Do not
- define prototypes for build_binary_op, or build_indirect_ref,

- argument, and rtl.h is included after tree.h.

- * cp-decl.c (poplevel): Reconciled with recent changes made to the
- `poplevel' routine in c-decl.c. The changes here cause LABEL_DECL
- nodes to be attached (as the BLOCK_VARS chain) to the BLOCK node
- which represent the outermost scope of the function.
+ * Makefile.in (doc): Depend on $(GENERATED_MANPAGES).
+ * doc/.cvsignore: Add gcc.1, cpp.1, gcov.1.
+ * doc/gcc.1, doc/cpp.1, doc/gcov.1: Removed.

- * cp-decl.c (pushtag): Handle structure tags in the same way as the
- C front-end. This completes a change that rms put in on 3/12/92 and

- 3/18/92.
+ * doc/install.texi (Specific, mips*-sgi-irix4): Split from IRIX 5
+ section.

- * cp-init.c (expand_aggr_init, expand_vec_init): When comparing
- array types, use `comptypes' instead of ==, since two array types
- may be structurally identical but not == if one was defaulted from
- an initializer.

- * mips.h (MIPS_VERSION): Bump Meissner version # to 20.
- (final_prescan_insn): Add declaration.
- (FINAL_PRESCAN_INSN): Just call final_prescan_insn.
- (CONST_OK_FOR_LETTER_P): Rewrite some tests, so that they will
- work on host systems with 64 bit integers.
+ * c-common.c (decl_attributes, case A_MODE): Don't call layout_decl
+ for FIELD_DECL.
- * mips.c (large_int): Rework, so that we don't get funny boundary
- conditions on systems with 64 bit integers.
- (mips_move_1word): Just use li to load constants that can be done
- with lui, instead of issuing the lui, since the GAS bug that
- generated two instructions has been fixed.
- (final_prescan_insn): Move the checking for filling the delay
- slots here from the FINAL_PRESCAN_INSN macro.
+2001-07-01 Geoffrey Keating <geoffk@redhat.com>
- * mips.md (andsi3, iorsi3, xorsi3): Make the constraints match
- the real machine (the predicate still is more general in order
- to optimize bitfields at the expense of not CSE'ing large
- constants used in logical ops, and making reload load it into
- a scratch register). Don't use $1 as a temporary register any
- more.
+ * doc/tm.texi (FUNCTION_ARG): Document that the last call
+ is special.
- * varasm.c (decode_reg_name): If `memory' return -4.

- * stmt.c (expand_asm_operands): If `memory' is used as a clobbered
- register, emit a (clobber (const_int 0)) to force the compiler not
- to cache memory values in registers across the assembly
- instruction(s).
+ * tlink.c (recompile_files): Remove COMPILER_PATH and
+ LIBRARY_PATH from the environment.
- * mips-tfile.c (read_line): Semicolons within strings are not
- counted as statement separators.

- * collect2.c (scan_prog_file, OSF/rose case): Cast pointer arguments
- to bcopy to generic * to avoid warnings.

+ RID_LAST_PQ. Move RID_FIRST_PQ down with the other FIRST/LAST
+ enumerators.

+ (reswords): Take the leading '@' off all the Objective-C keywords.
+ (objc_rid_sans_at): Kill.
+ (init_reswords): Don't initialize it.
+ (yylexname): Use OBJC_IS_AT_KEYWORD and OBJC_IS_PQ_KEYWORD.
+ (_yylex): Kill reconsider label. Look ahead one token after
+ an '@'; if we get an identifier, check whether it's an
+ Objective-C @-keyword. If so, return the keyword. Otherwise,
+ put back the token and return the '@' as a terminal.
- * c++: If given -v with no file args, don't pass the libraries to
- gcc.
+ * cpplib.c (lex_macro_node): Remove unnecessary check for
+ leading '@' on identifier. Clarify control flow and commentary.
