260 | ||
261 | * sparc.md (mulsi3,mulsidi3,umulsidi3,divsi3,udivsi3): Patterns | |
262 | added to support V8 sparc architectures. | |

266 | than two registers, then abort to avoid an infinite loop. | |
267 | (count_possible_groups): Skip to last reg of group, not first reg | |
268 | of next group. | |

275 | case a library call is done. | |
276 | ||

292 | ||
293 | * mips.c (lui_int): New function, return true if value fits in a | |
294 | LUI instruction. | |
295 | (final_prescan_insn): Move the checking for filling the delay | |
296 | slots here from the FINAL_PRESCAN_INSN macro. If the safe | |
297 | attribute is set, we do not need a NOP to fill a load delay slot. | |
298 | ||
299 | * mips.md (safe attribute): New attribute to indicate that the | |
300 | current insn is safe to fill a delay slot even if the register | |
301 | operand(s) are set in the load instruction which has the delay | |
302 | slot. This is for and/ior/xor expansions that have a large | |
303 | constant integer as operand[2]. The load of the constant can | |
304 | overlap the load. | |
305 | (andsi3, iorsi3, xorsi3): Replace logical define_insn's with | |
306 | define_expand's that either map directly to the hardware | |
307 | instruction, or have a clobbered register to load the large | |
308 | constant into. This is instead of using $1 to hold the | |
309 | intermeidate value. Set the safe attribute to yes for the cases | |
310 | where we need to load the integer. Add define_split's to break | |
311 | the large logical operations into the separate pieces. | |
312 | ||
313 | Wed Jun 3 00:00:36 1992 Richard Stallman (rms@mole.gnu.ai.mit.edu) | |

325 | something that isn't a comparison. | |
326 | ||

328 | ||
329 | * cccp.c (do_pragma): Don't warn about #pragma once if used in a | |

337 | ||
338 | * mips.c (mips_output_double): If REAL_VALUE_TO_TARGET_DOUBLE is | |
339 | defined, use it to split the floating point value into 2 long | |
340 | integers, and print them out in hex. Otherwise use .double. | |
341 | (mips_output_float): If REAL_VALUE_TO_TARGET_FLOAT is defined, use | |
342 | it to split the floating point value into a long integer, and | |
343 | print in out in hex. Otherwise use .float. | |
344 | ||
345 | * dec-osf1.h (new file): Config file for DEC's offical OSF/1 | |
346 | product (as opposed to the OSF/1 reference port from OSF). | |
347 | ||
348 | * configure: Support mips-dec-osf1 target. | |
349 | * config.sub: Support mips-dec-osf1 target. | |
350 | ||
351 | * decstatn.h (CPP_PREDEFINES): If CPP_PREDEFINES is defined, don't | |
352 | supply another definition. Also, define _SYSTYPE_BSD. | |
353 | ||
354 | Mon Jun 1 00:04:01 1992 Ron Guilmette (rfg at ncd.com) | |

361 | * calls.c (stack_arg_under_construction): New variable. | |
362 | (store_one_arg): Set stack_arg_under_construction before calling | |
363 | expand_expr if expand_expr might call a constructor to initialize | |
364 | a stack argument. | |
365 | (expand_call): Push the stack around function calls if | |
366 | stack_arg_under_construction is nonzero. | |
367 | Also copy structure_value_addr in that case. | |
368 | Push the stack around an inline function if it makes calls | |
369 | and there are outgoing arguments on the stack which must be preserved. | |
370 | Move the call to expand_cleanups_to before that. | |
371 | Do this stack adjustment before computing argument locations. | |

388 | ||
389 | * dwarfout.c (output_decl): Moved test for ERROR_MARK node out of | |
390 | switch statement and added a test for DECL_IGNORED_P after that. | |
391 | (dwarfout_file_scope_decl): Check input node to see if it is an | |
392 | ERROR_MARK before checking for DECL_IGNORED_P. Also makes sure that | |
393 | any node marked as DECL_IGNORED_P isn't also a function definition. | |

2681 | Set switch_table_difference_label_flag. | |
2682 | * 3b1.h, amix.h, m68ksgs.h (ASM_OUTPUT_CASE_END): Test that flag. | |

2686 | HPUX_ASM conds. | |
2687 | ||
2688 | * mips.c (output_block_move): If we get a case we can't handle, | |
2689 | don't print anything--just abort, because that implies a bug. | |
2690 | ||
2691 | * c-decl.c (c_decode_option): -ansi sets flag_no_nonansi_builtin, | |
2692 | not flag_no_builtin. | |
2693 | (init_decl_processing): Check flag_no_nonansi_builtin for alloca, etc. | |
2694 | ||
2695 | * dbxout.c (dbxout_symbol): Make pointer, not reference, | |
2696 | when variable's address is in a register. | |

2699 | ||
2700 | Thu Apr 16 16:17:13 1992 Mike Stump (mrs@mole.gnu.ai.mit.edu) | |
2701 | ||
2702 | * merge in Cygnus changes... | |
2703 | ||
2704 | Thu Apr 16 12:23:06 1992 Mike Stump (mrs@rtl.cygnus.com) | |
2705 | ||
2706 | * cp-call.c (build_method_call): propagate const around to avoid an | |
2707 | incorrect error message. This type of fix may now be necessary in | |
2708 | other parts of the compiler. This solves all but one known const | |
2709 | problems. | |
2710 | ||
2711 | Wed Apr 15 14:18:27 1992 Mike Stump (mrs@rtl.cygnus.com) | |
2712 | ||
2713 | * cp-type2.c (readonly_warning_or_error): because the compiler | |
2714 | is now warning about const alot more, for a release or two, | |
2715 | lets just warn about const problems, just in case it is a compiler | |
2716 | problem and not a user problem. | |
2717 | ||
2718 | * cp-cvt.c (build_up_reference): Lets get tougher on const problems | |
2719 | on COMPONENT_REFs. | |
2720 | ||
2721 | Wed Apr 15 11:59:42 1992 Jim Wilson (wilson@sphagnum.cygnus.com) | |
2722 | ||
2723 | * cp-decl.c (finish_function): Check for any debug info enabled, | |
2724 | not just DBX_DEBUG. | |
2725 | ||
2726 | Wed Apr 15 10:03:36 1992 Mike Stump (mrs@rtl.cygnus.com) | |
2727 | ||
2728 | * cp-cvt.c (build_up_reference): Propagate const and volatile | |
2729 | down into the type so error checking works better. | |
2730 | ||
2731 | Tue Apr 14 11:44:32 1992 Mike Stump (mrs@rtl.cygnus.com) | |
2732 | ||
2733 | * cp-decl.c (start_decl): Shouldn't use flag_this_is_variable | |
2734 | to make what this points to const, but I don't have the heart | |
2735 | to do it right now. | |
2736 | ||
2737 | * cp-decl2.c (grokclassfn): Don't use flag_this_is_variable | |
2738 | to make what this points to const. | |
2739 | ||
2740 | * cp-typeck.c (convert_arguments): Let build_up_reference handle | |
2741 | const errors correctly. Removes April 10 change. | |
2742 | ||
2743 | * cp-cvt.c (build_up_reference): Don't let people subvert const | |
2744 | when passing const argements to non-const functions. | |
2745 | ||
2746 | * cp-tree.c (build_cplus_method_type): Don't use | |
2747 | flag_this_is_variable to make what this points to const. | |
2748 | ||
2749 | From Wed Apr 1 12:00:59 1992 Chip Salzenberg (chip at tct.com) | |
2750 | ||
2751 | * cp-class.c (import_export_vtable): New function to set | |
2752 | TREE_PUBLIC and/or TREE_EXTERNAL on vtables. | |
2753 | (build_vtable): Use it. | |
2754 | (prepare_fresh_vtable): Use it. | |
2755 | ||
2756 | * cp-decl.c (finish_decl): Don't assume that TREE_PUBLIC means | |
2757 | "exported"; it can mean "imported". Decide with TREE_EXTERNAL. | |
2758 | (finish_function): Ditto. | |
2759 | * cp-decl2.c (write_vtable_entries): Ditto. | |
2760 | (finish_vtable_typedecl): Ditto. | |
2761 | (finish_vtable_vardecl): Ditto. | |
2762 | (finish_file): Ditto. | |
2763 | ||
2764 | * cp-lex.c (set_vardecl_interface_info): Public objects always | |
2765 | have TREE_PUBLIC, whether exported or imported. | |
2766 | * cp-pt.c (instantiate_member_templates): Ditto. | |
2767 | ||
2768 | ||
2769 | Fri Apr 10 21:44:15 1992 Per Bothner (bothner@cygnus.com) | |
2770 | ||
2771 | * cp-method.c (build_overload_name): Mangle 'signed char' | |
2772 | as 'Sc' (i.e. differently from 'char'!). | |
2773 | ||
2774 | Fri Apr 10 17:38:04 1992 Mike Stump (mrs@cygnus.com) | |
2775 | ||
2776 | * cp-typeck.c (convert_arguments): don't allow people to wipe const. | |
2777 | ||
2778 | Thu Apr 9 18:28:36 1992 Mike Stump (mrs@rtl.cygnus.com) | |
2779 | ||
2780 | * cp-tree.h: Add entry for $vb and $vf so that NO_DOLLAR_IN_LABEL | |
2781 | works. | |
2782 | * cp-class.c (finish_struct): Use the new macros from cp-tree.h. | |
2783 | * cp-tree.c (layout_basetypes): Use the new macros from cp-tree.h. | |
2784 | ||
2785 | Thu Apr 9 02:11:01 1992 Mike Stump (mrs@rtl.cygnus.com) | |
2786 | ||
2787 | * cp-typeck.c (build_function_call_real): Merge in a change made to | |
2788 | the C front end into the C++ front end to handle volatile functions. | |
2789 | ||
2790 | Thu Apr 9 03:45:03 1992 Mark Eichin (eichin at cygnus.com) | |
2791 | ||
2792 | * cp-class.c (finish_struct): sanity check before calling popclass. | |
2793 | If we're already hosed due to previous parse errors (specifically, | |
2794 | we're not inside a class anymore) just report an error rather than | |
2795 | crashing in popclass (if there wasn't a previous parse error, as the | |
2796 | message suggests, we should get reports; this closes gcc/p0000525.) | |
2797 | ||
2798 | Wed Apr 8 08:56:49 1992 Mike Stump (mrs@rtl.cygnus.com) | |
2799 | ||
2800 | * cp-decl.c (grokdeclarator): Fix an eichin bug introduced seconds | |
2801 | ago. Shame, he didn't put: | |
2802 | ||
2803 | Workaround for p869: | |
2804 | 1) grokdeclarator (around cp-decl.c:7462) is using popclass(1) | |
2805 | uses popclass(1) to close the pushclass(3) done by | |
2806 | build_push_scope; however, it's coming around another time and | |
2807 | popping all the way out, which leads to the core dump when | |
2808 | do_friend is called from global scope (do_friend uses | |
2809 | current_class_name to figure out whose friendship it is | |
2810 | bestowing.) Current workaround: if (friendp) don't allow | |
2811 | popping all the way out. We still need to figure out how to | |
2812 | make sure it only gets called the *right* time; we also need | |
2813 | to figure out if the correct scope is being used, but that's a | |
2814 | matter of regression testing. | |
2815 | ||
2816 | into a ChangeLog entry. | |
2817 | ||
2818 | Wed Apr 8 01:10:44 1992 Mike Stump (mrs@rtl.cygnus.com) | |
2819 | ||
2820 | * cp-decl.c: Cleanup binding_levels_sane related code. Deleted | |
2821 | argument, and changed to void type. Removed extraneous asserts. | |
2822 | ||
2823 | * cp-parse.y: Add fourth parameter to all finish_decl calls. | |
2824 | Defaulted the guess to 0. | |
2825 | * cp-decl.c: consistently use #if on all PARANOIDs. | |
2826 | ||
2827 | Wed Apr 15 14:00:14 1992 Michael Meissner (meissner@osf.org) | |
2828 | ||
2829 | * mips.md (movstrsi_internal): Add '&' constraint on clobbers. | |
2830 | ||
2831 | * mips.c (output_movstrsi): If one of our temporary registers is | |
2832 | used as an address register, don't use it and emit a warning. This | |
2833 | is a temporary measure. | |
2834 | ||
2835 | Wed Apr 15 09:04:22 1992 Richard M. Stallman (rms at lyssenko) | |
2836 | ||
2837 | * xm-ns32k.h (memcpy, memcmp, memset): New macro definitions. | |

2847 | Tue Apr 14 13:28:11 1992 Jim Wilson (wilson@wookumz.gnu.ai.mit.edu) | |
2848 | ||
2849 | * c-lex.c (yylex): When warn_traditional, don't abort for harmless | |
2850 | type differences. Instead warn of possible problems on other systems. | |
2851 | ||
2852 | * rtl.c (add_dependence): Skip notes when HAVE_cc0. | |
2853 | * sched.c (sched_analyze_2): Likewise. | |
2854 | ||
2855 | * sparc.md (movdf-1): Delete special case for moving 0.0 to integer | |
2856 | registers; it resulted in poor code. | |
2857 | (fix_truncdfsi2+1): Add patterns to optimize float->fix and | |
2858 | float->fix->float conversions. | |
2859 | * sparc.c (output_move_double): Clean up ldd/std code. Don't emit | |
2860 | ldd/std for obviously unaligned address even when TARGET_HOPE_ALIGN. | |
2861 | (output_fp_move_double): Call output_move_double for MEM cases. | |
2862 | It is not safe to assume double reg addresses are always aligned. | |
2863 | ||

2872 | Tue Apr 14 05:46:37 1992 Tom Wood (wood at dg-rtp.dg.com) | |
2873 | ||
2874 | * Makefile.in ("if" and "["): Romp, 4.3 BSD, and Ultirx systems | |
2875 | fail when the condition is false. Change troublesome instances to | |
2876 | either use "case" or use '-' as a prefix to the compilation rule. | |
2877 | ||
2878 | Mon Apr 13 18:20:56 1992 Mike Stump (mrs@cygnus.com) | |
2879 | ||
2880 | * dwarfout.c: Add default definition for ASM_OUTPUT_ASCII | |
2881 | as that is what varasm.c does now. This really maybe should go | |
2882 | into a file like tree.h or some machine independant file, for | |
2883 | maintainability. | |
2884 | ||
2885 | Mon Apr 13 18:16:32 1992 Jim Wilson (wilson@wookumz.gnu.ai.mit.edu) | |

2896 | expensive. | |
2897 | (cse_insn): Make extra entries when DEST is a multi-word SUBREG | |
2898 | as long as it is the same number of words as its inner REG. | |
2899 | ||
2900 | * emit-rtl.c (gen_lowpart_common): Handle casting integer to | |
2901 | float and vice versa. | |
2902 | ||
2903 | * emit-rtl.c (gen_lowpart_common): Rework code to truncate a | |
2904 | constant so we don't convert negative values into positive values; | |
2905 | use same code as in simplify_binary_operation in cse. | |

2942 | constant equivalent. | |
2943 | ||
2944 | * expr.c (store_constructor): If building a static constructor | |
2945 | into a register, start out by zeroing the register so we can | |
2946 | constant-fold the constructor to a single constant. | |
2947 | (expand_expr, case CONSTRUCTOR): Don't write constant objects | |
2948 | into memory if the target is a register. | |
2949 | (expand_expr, case *_REF): Simplify getting field or array | |
2950 | entry from a CONSTRUCTOR. | |

2995 | * c-decl.c (init_decl_processing): Make -fno-builtin supress all | |

3006 | * rs6000.md (addsi3, andsi3, iorsi3, xorsi3, cmpsi3): Remove | |

3008 | ||

3010 | split_insns before trying find_split_point. | |

3179 | forced to a register. | |
3180 | ||
3181 | * decrose.h (HALF_PIC_DEBUG): Define as true if -mdebugb, to debug | |
3182 | the half-pic code, just like debugging normal addressing. | |

6060 | of methods of uninstantiated types. | |
6061 | ||
6062 | * cp-pt.c (instantiate_template): If no text has been saved away, | |
6063 | don't try to parse it; an external reference will result. | |
6064 | ||
6065 | * cp-parse.y (yyprint): Declare this at head of file. | |
6066 | ||
6067 | * cp-pt.c (instantiate_class_template): If the template specified | |

6072 | gracefully. | |

6094 | ||
6095 | * i386.md (casesi): Rewrite pattern to reflect the way to emitted | |

6128 | (simplify_comparison, case ASHIFT): If shifting low-order bit to | |
6129 | sign bit and doing equality comparison, convert to AND with low-order | |
6130 | bit (inequality case was already handled). | |
6131 | Also remove redundant test of CONST_OP in an earlier case. | |
6132 | ||

6134 | ||
6135 | * m68k.c, m68k.h: Avoid %X% for most upper-case X since it means | |
6136 | something special to SCCS. | |
6137 | ||
6138 | * rs6000.md (type): Add new type, mtlr. | |
6139 | (function_unit branch): Add delay from mtlr to br. | |

6161 | ||
6162 | * m68k.md, vax.md (sob): Rewrite inequality versions so that they | |
6163 | have a PLUS inside the comparison; combine cannot remove the PLUS | |

6178 | * cp-typeck.c (convert_arguments): An argument that's an OFFSET_REF | |
6179 | must be resolved by `resolve_offset_ref'. The OFFSET_REF case in | |
6180 | expand_expr does not do the right thing for G++ yet. | |
6181 | ||
6182 | * cp-decl.c (grokdeclarator): Take CONSTP and VOLATILEP into account | |

6199 | ||
6200 | * m88k.md (cmpsi insn): Delete alternative that complements the | |
6201 | compare string for a swapped compare (it's wrong and unnecessary). | |
6202 | (cpu attribute): Define. | |
6203 | ||
6204 | From Jyrki Kuoppala: | |
6205 | * pc532.h, pc532-mach.h, pc532-min.h, xm-ps532-min.h: New files. | |

6223 | ||
6224 | * configure (i386-sequent-bsd*): Use seq386gas.h if --gas. | |
6225 | (i386-*-sco*): The host file is now xm-i386sco.h. | |

6228 | testing one byte of a mem, use a byte test opcode. | |

6267 | COND_EXPRs must evaluate LHS in conditional slot if LHS has side | |
6268 | effects. Otherwise the SAVE_EXPRs in lhs will only be evaluated | |
6269 | once, even though they are referenced on both branches of the | |
6270 | conditional. | |
6271 | ||
6272 | Sat Feb 29 13:32:35 1992 David J. MacKenzie (djm@nutrimat.gnu.ai.mit.edu) | |

6342 | ||
6343 | * sched.c (schedule_insns): Don't update value of reg_live_length | |
6344 | when it is negative, because negative values are special. Earlier | |
6345 | fix Dec 17 disabled the fprintf call, but not the assignment. | |
6346 | ||
6347 | * unroll.c (copy_loop_body): After incrementing the base reg for a | |

7908 | case we have a named return value. | |
7909 | (finish_function): Restrict the cases under which we build | |

7950 | support these in GCC 2.00. Readjust the positions the bits are in. | |
7951 | (TARGET_OPTIONS): Define to add switches -mcpu=x to set which | |
7952 | processor type to schedule for, and -mipsx to specify the | |
7953 | instruction set architecture level. | |

7991 | ||
7992 | * cp-decl.c (set_identifier_local_value): New function. Clone of | |
7993 | set_identifier_type_value, but uses level->shadowed instead. Only | |
7994 | used in pushdecl, where the non-global install was previously | |
7995 | setting the local value directly which "stuck" and didn't get | |
7996 | cleared the next time through. | |
7997 | (pushdecl): use set_identifier_type_value so that the local value | |
7998 | actually gets erased when we leave this level. Changed code that | |
7999 | checks for global_binding_level to recognize that if | |
8000 | class_binding_level is set, we're not in the global one. | |
8001 | (poplevel_class): restore shadowed list too, like poplevel does. | |
8002 | (print_binding_level): added no_print_functions and | |
