| * va-pa.h : When __GNUC__ == 1, don't include the gcc 1 varargs |

| TARGET_SNAKE. |

| patterns. These are needed because SImode and DImode pseudoregs |
| may be allocated (or reloaded) in floating point registers for |

| 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, |
| REG_CLASS_FROM_LETTER): Define a new register class |
| FP_OR_SNAKE_FP_REGS, used only be reload_{in,out}{si,di}. |
| (HARD_REGNO_MODE_OK): Allow all integer modes in Snake floating |
| point registers. QImode and HImode pseudoregs may end up there |
| when using xmpyu. |

| (movsi, movdi patterns): Remove some * constraints from fp registers. |

| 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 |
| docs from HP were wrong. |
| (ASM_DECLARE_FUNCTION_NAME): Specify "ENTRY" param in .EXPORT |
| directive. |
| (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 |
| now; their only use (saving stuff during profiling) interacts in a |
| wierd way with required assembler directives at the start of a |
| function. Instead, do the save and restore in the function |
| prologue. |
| (hppa_encode_label): Declare. |
| * pa-hpux.h, pa-ghpux.h (TARGET_DEFAULT): Link against shared |
| libraries. |
| (LINK_SPEC): Don't link against shared libraries if debugging or |
| profiling. |
| * pa1-hpux.h, pa1-ghpux,h (TARGET_DEFAULT): Link against shared |

| (out_operand): Allow special registers with any mode. |
| Any MEM a word or wider is valid. |

| |
| * mips-tfile.c (various): Rename some of the index variables and |
| fields to indx, so that it doesn't conflict with the BSD |

| |
| * pa.c (emit_move_sequence): When making a reference to the data |
| space before reload, emit an insn sequence which is much more |

| |
| * cp-class.c (finish_struct), cp-tree.c (layout_basetypes): |

| Wed Aug 26 15:42:11 1992 Jeffrey A. Law (law@schirf.cs.utah.edu) |
| |
| 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. |

| unconditional jump. |
| (fill_simple_delay_slots): Look for the case of a call/branch |

| (output_floatsisf2, output_floatsidf2, output_floatsitf2): Delete. |
| * sparc.h: Delete declarations of the above 3 functions. |
| * sparc.md (float*, fix*): Rewrite to match hardware; take/put |
| integer input/output from/to fp register instead of memory or |
| general register. Delete 6 now obsolete combiner patterns. |

| actual_hazard_this_instance, actual_hazard, potential_hazard, |
| schedule_select): New functions. |
| (schedule_block): Add dependencies to force insns to remain in order |
| at the end of a block rather than relying on having the scheduler |

| changed. Supply an ADJUST_COST interface. |
| (insn_cost): Make a dependence from a USE insn free. |

| Tue Aug 25 13:38:19 1992 Michael Meissner (meissner@osf.org) |
| |
| * 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 |

| linker doesn't think a second frame pointer is created. |
| (INITIAL_FRAME_POINTER_OFFSET): Don't define, since we use |
| elimination instead. |
| (ELIMINABLE_REGS): Define to eliminate both the stack pointer and |
| frame pointer, since they are now separate. |

| change the base of the gp registers. |
| (MIPS_STACK_ALIGN): Use ~7, instead of 0xfffffff8. |
| |
| * mips.c (number_functions_processed): Delete variable, nobody |
| uses it anymore. |
| (mips_debugger_offset): Add support for the frame pointer being |
| the same as the stack pointer, instead of being the same as the |
| argument pointer. Abort if the address is not based on any of the |
| stack, frame, or argument pointers. |
| (print_operand_address): Add checks for the arg pointer not being |
| eliminated. |
| (function_prologue): Ditto. |
| (mips_expand_prologue): Ditto. |
| (function_epilogue): Ditto. |
| (mips_expand_epilogue): Ditto. |
| (function_epilogue): Strip leading '*' if it exists from |
| current_function_name when printing statistics. Delete increment |
| of number_functions_processed. |
| (compute_frame_size): Don't base extra_size on the macro |
| STARTING_FRAME_OFFSET. If function is a leaf function, but calls |
| __builtin_alloca, allocate an arg area, so that the MIPS linker |
| will not complain about creating a second frame pointer. Move the |
| argument save area beneath local variables. |
| |
| * decrose.h (ASM_FINAL_SPEC): Use %U to get the last file name |
| created with %u, rather than %u. |
| |
| * gcc.c (do_spec_1): Add %U to return the last name generated with |
| %u. This is for use with mips-tfile, to find the generated object |
| file. |

| if staticp, but don't clear TREE_CONSTANT. |
| |
| Mon Aug 24 13:52:13 1992 Brendan Kehoe (brendan@cygnus.com) |
| |
| * gcc.c (process_command): Don't set verbose_flag if they make a |
| typo (e.g., `-v-E'); only when it's exactly "-v". |
| |
| Mon Aug 24 06:49:16 1992 Richard Kenner (kenner@vlsi1.ultra.nyu.edu) |
| |
| * combine.c (subst): When moving operation inside IF_THEN_ELSE, |
| make a new rtx instead of using SUBST due to sharing. |
| |
| * combine.c (simplify_comparison): Correct test for sign extension |
| when trying to widen comparison. |
| |
| Sun Aug 23 18:58:33 1992 Richard Stallman (rms@mole.gnu.ai.mit.edu) |

| |
| * stmt.c (expand_end_bindings): Generation of NOTE_INSN_BLOCK_END |
| moved down so that it occurs after call to `expand_cleanups'. |

| |
| * decrose.h (CPP_SPEC): Don't define strcmp as __builtin_strcmp in |
| the case neither -fbuiltin nor -fno-builtin were defined. |
| * i386rose.h (CPP_SPEC): Ditto. |
| |
| Sun Aug 23 02:03:41 1992 Richard Stallman (rms@mole.gnu.ai.mit.edu) |

| these attributes are useless. All references deleted. |
| (call define delay): Use "in_branch_delay" as the condition since |
| "call" delay slots and unconditional "branch" delay slots allow the |
| same type of insns. |
| (in_call_delay conditional): Deleted. |
| (branch define delay): Do not define an annul-if-true delay slot. |
| It is useless for an unconditional branch. |
| (all delay branch conditionals): Make sure "call", "dyncall", "multi", |
| and "milli" insns are explicitly disallowed in delay slots. |

| (build_vbase_vtables_init): Ditto. |
| |
| * genflags.c (insn_name_ptr): Define, so that we can link in |
| print-rtl.c for debugging. |
| (call_obstack, normal_obstack): New obstacks to remember call |
| insns, and normal insns, so that we can emit the prototypes later. |
| (max_id_len): New variable to record the maximum identifier |
| length. |
| (num_operands): New function to return the number MATCH_OPERAND's |
| and MATCH_OPERATOR's in an insn tree. |
| (gen_proto): New function to print out a prototype for an insn. |
| (gen_nonproto): New function to print out a declaration without a |
| prototype. |
| (gen_insn): Don't emit function declarations here, just save the |
| insn on either the call_obstack if it is call or call_value, or |
| normal_obstack otherwise. |
| (main): Initialize call_obstack, normal_obstack. After all insns |
| are processed, emit function declarations with and without |
| prototypes, depending on whether NO_MD_PROTOTYPES, and |
| CALL_MD_PROTOTYPES are defined. |
| |
| * rtl.h (PROTO): If not defined, define to either expand |
| prototypes or just expand to (), depending on whether or not, the |
| host compiler supports ANSI C. |

| where it is feasible to do so, using the PROTO macro. |

| host compiler supports ANSI C. |
| (NULL_PTR): Define as void * if we have prototypes. |
| (all function declarations): Add prototypes for all functions |
| where it is feasible to do so, using the PROTO macro. Do not |
| define prototypes for build_binary_op, or build_indirect_ref, |
| since GNU C and GNU G++ have different numbers of arguments. Do |
| not define prototypes for make_tree, since it takes a rtx as the |
| argument, and rtl.h is included after tree.h. |
| |
| Sat Aug 8 07:36:19 1992 Tom Wood (wood@dg-rtp.dg.com) |

| |
| * pa.h (ASM_FILE_START): If profiling IMPORT "_mcount" instead of |
| "__gcc_mcount". |
| |
| * These changes allow the PA to make use of the BSS subspace. They |
| require you to use the HPUX assembler or a fixed version of pa-gas |
| (available soon on jaguar.cs.utah.edu). |
| * pa.h (TARGET_SWITCHES): New switch "no-bss" which forces gcc not |
| to make use of the bss subspace. (For compatability with old buggy |

| |
| * gcc.c (default_compilers): For output of as when -c is not used, |
| use %g, rather than %b, because the file is going to be deleted |

| |
| * cp-decl.c (grokdeclarator): Call build_type_variant to set const |

| |
| * cp-tree.h (hash_chainon): Add declaration for this function. |

| |
| Complete 10th FSF <---> Cygnus merge. |
| |
| Tue Aug 4 12:58:59 1992 Mike Stump (mrs@cygnus.com) |
| |
| * cp-decl.c (pushtag): Don't set DECL_IGNORED_P for binding |
| layer markers, use only DECL_SOURCE_LINE == 0, as otherwise, |
| it messes up dbxout.c. |
| |
| Tue Aug 4 11:59:36 1992 Mike Stump (mrs@cygnus.com) |

| |
| Sun Aug 2 21:12:55 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com) |
| |
| * cp-tree.c: change definition of __eprintf to match libgcc2.c and |
| assert.h |
| |
| Fri Jul 31 16:53:26 1992 Mike Stump (mrs@cygnus.com) |
| |
| * cp-tree (break_out_calls): Only make ony copy of a node on |
| 's' and 'e' nodes. Handle 'r' just like 's' and 'e' because |
| nodes of type 'r' can be of different sizes (the old code |
| would do the wrong thing for a COMPONENT_REF). |
| |
| Thu Jul 30 11:46:14 1992 Michael Tiemann (tiemann@rtl.cygnus.com) |
| |
| * cp-init.c (emit_base_init): Set transparent basetypes (those w/o |

| |
| Wed Jul 29 03:25:51 1992 Michael Tiemann (tiemann@rtl.cygnus.com) |
| |
| * cp-decl.c (grokdeclarator): In SCOPE_REF case, sort out visibility |
| declarations from other declarations, since the compiler will |
| ultimately handle them differently. This is a part of the solution |
| to p525. |
| (finish_method): Tentative (and probably wrong) fix for carrying |
| along inline methods delcared within a class that really belong to |
| nested classes of the class. This may be more of the solution to |

| |
| Tue Jul 28 22:43:12 1992 Mark Eichin (eichin@cygnus.com) |
| |
| * cp-pt.c (end_template_instantiation) YYDEBUG is now defined in |
| cp-parse.h -- so don't assume that it's -2 (since under byacc it is |
| -1 anyway.) iomanip.C compiles again. |
| |
| Tue Jul 28 22:33:46 1992 Mike Stump (mrs@cygnus.com) |
| |
| * cp-typeck.c (build_c_cast): Allow cast to array type in |

| |
| * cp-parse.y (print_parse_statistics): don't reference TOKEN_LENGTH |
| or REDUCE_LENGTH unless GATHER_STATISTICS is set. (YYDEBUG alone is |

| |
| * cp-tree.c (break_out_calls): Don't do anything special to |
| SAVE_EXPRs, as they cannot contain calls that would need |
| breaking out. This fixes a problem introduced on Jul 15, by |
| Ron Guilmette. |
| |
| Mon Jul 27 16:55:52 1992 Mike Stump (mrs@cygnus.com) |
| |
| * c++: Fix errors introduced by rms. Bullet-proof handling |
| of arguments with funny things in them such as newlines, |
| spaces, tabs, single quotes, double quotes, etc... |
| |
| Mon Jul 27 15:03:23 1992 Ken Raeburn (raeburn@cygnus.com) |
| |
| * cp-init.c (build_vec_delete): Extract size of type even for |
| destructorless types, so value can be computed to pass to delete |
| operator. |
| |
| * Bludgeon interface/implementation code into leaving templates |
| alone, until we've figured out how to handle their interaction |
| properly: |
| * cp-parse.y (template_instantiate_once): Temporarily set interface |
| flags to `unknown' while processing member templates. |
| * cp-decl.c (grokfndecl): Even if class vtable is getting written |
| out, regardless of interface setting of class and write_virtuals |
| flag, don't force virtual destructor of template class to be public. |
| * cp-tree.h (struct pending_inline): New field `interface'. |
| * cp-lex.c (do_pending_inlines): Restore interface flags from stored |
| values, rather than calling extract_interface_info. |

| |
| * cp-parse.y (structsp): note_got_semicolon was called before |
| finish_struct (which always clears the got_semicolon bit.) However, |
| note_got_semicolon was only called if yychar==';', without checking |
| for YYEMPTY. |
| |
| Tue Jul 21 22:59:32 1992 Michael Tiemann (tiemann@rtl.cygnus.com) |
| |
| * cp-typeck.c (mark_addressable): If we have a recursive call to an |
| otherwise inline function, clear TREE_EXTERNAL so the whole function |
| is written to the asm file. |
| |
| Tue Jul 21 05:31:10 1992 Ken Raeburn (raeburn@cygnus.com) |
| |
| * cp-tree.h (start_type_method): Deleted unused declaration. |
| |

| type that promotes to int, promote it unsigned if traditional |
| or if it is the same size as int. |
| (start_function): Ditto for function return value. |
| * c-typeck.c (default_conversion): Ditto -- fix bug that |
| promotes short to unsigned if sizeof(short) == sizeof(int). |

| moving between FP <-> GP registers. |
| |

| from cast type. When casting to a reference to T, really just |
| cast to T. |
| |
| * cp-cvt.c (build_up_reference): Make a copy of a node before |
| changing it. Only propagate the const bit if we are not |
| subverting it. |

| Wed Jun 3 13:25:26 1992 Ken Raeburn (Raeburn@Cygnus.COM) |
| |
| * cp-parse.y (template_instantiate_once): Set |
| CLASSTYPE_GOT_SEMICOLON to eliminate messages about missing |
| semicolons. |
| |
| * cp-decl.c (start_function): Don't emit error message for missing |
| semicolon after class decl; that syntax (declaring both class and |
| function returning that type) should be legal. Do emit a warning if |
| it's not an anonymous name. |

| |
| * cp-decl.c (pushdecl): Re-fix May 12 change regarding DECL_CONTEXT. |
| * cp-call.c (build_method_call): Go back to using DECL_CONTEXT |
| instead of DECL_CLASS_CONTEXT. DECL_CONTEXT says when a function |
| was first declared virtual in a class, which is needed information |
| in case the virtual function comes from a virtual baseclass (because |
| the derived class won't have a vtable entry for that function (if it |
| has a vtable at all!)). |

| Tue May 26 10:07:02 1992 Mike Stump (mrs at cygnus.com) |
| |
| * cp-parse.y (return_init): Fix simple typo that caused '=' |

| |
| Wed May 20 09:09:08 1992 Michael Tiemann (tiemann@rtl.cygnus.com) |
| |
| * cp-call.c (build_method_call): Use DECL_CLASS_CONTEXT, not |
| DECL_CONTEXT to find the class in which FUNCTION was declared (for |
| non-virtual calls). |
| |
| Tue May 19 02:08:39 1992 Mike Stump (mrs at cygnus.com) |
| |
| * cp-parse.y (component_decl): Remove some bogus code that |
| prevents empty nested union definitions from compiling. |
| |
| Tue May 19 01:08:23 1992 Mike Stump (mrs at cygnus.com) |
| |
| * cp-decl.c (grokfndecl): Propagate volatile from type of |
| function out to the decl for the function. |
| |
| Mon May 18 17:19:39 1992 Mike Stump (mrs at rtl.cygnus.com) |
| |
| * cp-search.c (get_binfo): Since unions cannot participate in |
| inheritance relationships, return 0 instead of aborting. |
| |
| Fri May 15 13:37:40 1992 Mike Stump (mrs at cygnus.com) |
| |
| * cp-parse.y (template_type_name): Handle |

| |
| Mon May 11 14:10:50 1992 Ron Guilmette (rfg at ncd.com) |
| |
| * 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. |
| |
| Mon May 11 12:35:44 1992 Ron Guilmette (rfg at ncd.com) |
| |
| * cp-class.c (finish_struct): Check DECL_CONTEXT to see if it is |
| any sort of a type (e.g. struct *or* union) rather than just |
| checking it to see if it's a RECORD_TYPE. |
| * cp-decl.c (pushdecl): Set DECL_CONTEXT of pushed ..._DECL node, |
| just as is done in c-decl.c. |
| (pushdecl): Delete useless variable `cntxt'. |
| (finish_decl): Set TREE_USED rather than DECL_FROM_INLINE in order |
| to prevent "unused" warnings. |
| (finish_function): Check DECL_CONTEXT to see if it is a type. |
| (finish_function): Fixed indentation problem. |
| * cp-gc.c (build_m_desc): Check DECL_CONTEXT to see if it is a type. |
| * cp-init.c (build_virtual_init): Fix indentation. |
| * cp-lex.c (store_pending_inline): Check DECL_CONTEXT to see if it |
| is a type. |
| * cp-pt.c (tsubst, do_pending_expansions): Check DECL_CONTEXT to see |
| if it is a type. |
| * cp-typeck.c (mark_addressable): Check DECL_CONTEXT to see if it is |
| any sort of a type (e.g. struct *or* union) rather than just |
| checking it to see if it's a RECORD_TYPE. |
| |
| Tue May 12 08:52:06 1992 Michael Tiemann (tiemann@rtl.cygnus.com) |
| |
| * cp-typeck.c (build_component_ref): Call `break_out_cleanups'. |
| Also clean up indentiation. |
| |
| Mon May 11 23:14:04 1992 Mike Stump (mrs at cygnus.com) |
| |
| * 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 |
| I put in the Cygnus tree on 3/13/92 and Mark Eichin took back out on |
| 3/18/92. |
| |
| Sun May 3 00:29:59 1992 Mike Stump (mrs at cygnus.com) |
| |
| * cp-lex.c (copy_lang_decl, store_pending_inline): Cast |
| arguments to bcopy to be char *. |
| |
| Fri May 1 12:22:31 1992 Michael Tiemann (tiemann@cygnus.com) |
| |
| * 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. |
| |
| Wed Apr 29 01:25:25 1992 Mike Stump (mrs at cygnus.com) |
| |
| * cp-init.c (do_friend): Check that PREVIOUS_DECL is non-NULL. |
| |
| Thu Jun 18 14:15:07 1992 Torbjorn Granlund (tege@hal.gnu.ai.mit.edu) |
| |
| * pa.md (insv): Use `+' for operand 0 constraint. |
| |
| Thu Jun 18 13:39:22 1992 Michael Meissner (meissner@osf.org) |
| |
| * 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. |
| |
| * 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. |
| |
| * 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. |
| |
| * 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). |
| |
| * 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. |
| |
| Thu Jun 18 12:04:53 1992 David J. MacKenzie (djm@wookumz.gnu.ai.mit.edu) |
| |
| * c++: If given -v with no file args, don't pass the libraries to |
| gcc. |
| |
| Thu Jun 18 10:34:22 1992 Tom Wood (wood@dg-rtp.dg.com) |
| |
| * expr.c (expand_builtin, BUILT_IN_FSQRT): Emit queue of increment |
| instructions before starting a sequence that may get thrown away. |
