2620 * configure.in (sysconf): Call AC_CHECK_FUNCS.
2622 Wed Jan 14 20:10:51 1998 Paul Eggert <eggert@twinsun.com>
2624 * cccp.c: (rescan): Don't report line 0 as the possible real start
2625 of an unterminated string constant.
2626 Don't mishandle backslash-newlines that in are the output of
2627 a macro expansion. Properly skip // style comments between a function
2628 macro name and '(', as well as backslash-newlines in comments there.
2629 (handle_directive): Handle / \ newline * between # and directive name.
2630 In #include directives, \ does not escape ".
2631 (do_include): For `#include "file', do not bother expanding into temp
2632 buffer. When error encountered when expanding, do not try result.
2633 (skip_if_group): When skipping an include directive, use include
2634 tokenization, not normal tokenization. Backslash-newline is still
2635 special when skipping. Handle * \ newline / correctly in comments
2636 when skipping.
2637 (skip_quoted_string): After \ newline, set *backslash_newlines_p
2638 even if count_newlines is 0.
2639 (macroexpand): Newline space is not a special marker inside a string.
2640 (macroexpand, macarg): Do not generate \ddd for control characters
2641 when stringifying; the C Standard does not allow this.
2642 (macarg1): New arg MACRO. All callers changed.
2643 Do not treat /*, //, or backslash-newline specially when processing
2644 the output of a macro.
2645 (discard_comments): Don't go past limit if looking for end of comment.
2646 Discard backslash-newline properly when discarding comments.
2647 (change_newlines): \" does not end a string.
2648 (make_definition): Do not treat backslash-newline specially, as it
2649 has already been removed before we get here.
2651 * profile.c (output_func_start_profiler): Don't fflush output
2652 if -quiet.
2653 * toplev.c (rest_of_compilation): Likewise.
2655 * i386/x-sco5 (CC): Remove trailing white space.
2656 * x-convex (CCLIBFLAGS): Likewise.
2657 * arm/t-semi (LIBGCC2_CFLAGS): Likewise.
2659 Wed Jan 7 18:02:42 1998 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
2661 * Version 2.8.0 released.
2663 Wed Jan 7 17:54:41 1998 J. Kean Johnston <jkj@sco.com>
2665 * i386/sco5.h ({END,START}FILE_SPEC): Link with correct crtbegin.o
2666 and crtend.o when using -static.
2668 Wed Jan 7 17:49:14 1998 Jan Christiaan van Winkel <Jan.Christiaan.van.Winkel@ATComputing.nl>
2670 * cppexp.c (gansidecl.h): Include.
2672 Wed Jan 7 17:45:07 1998 Tristan Gingold <gingold@puccini.enst.fr>
2674 * expr.c (get_push_address): Use copy_to_reg instead of force_operand.
2675 (emit_push_insn): Avoid null pointer deference if aggregate has no
2676 types.
2677 (expand_expr): Avoid finite but useless recursion.
2678 (expand_builtin): Fix typo in calling function.
2679 * function.c (assign_parms): Avoid useless call to chkr_set_right.
2681 Wed Jan 7 17:31:13 1998 Christian Iseli <Christian.Iseli@lslsun.epfl.ch>
2683 * combine.c (force_to_mode): Return if operand is a CLOBBER.
2685 Wed Jan 7 17:23:24 1998 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
2687 * x-rs6000 (INSTALL): Remove.
2689 * jump.c (jump_optimize): Don't use a hard reg as an operand
2690 of a conditional move if small register classes.
2692 Wed Jan 7 17:09:28 1998 Jim Wilson <wilson@cygnus.com>
2694 * cse.c (max_insn_uid): New variable.
2695 (cse_around_loop): Use it.
2696 (cse_main): Set it.
2698 See ChangeLog.11 for earlier changes.
