From: John Carr Date: Sun, 6 Sep 1998 05:51:59 +0000 (+0000) Subject: final.c (final): If a label is reached only from a single jump... X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0d83c20351c5e7557ce5b8eaf48d9bdcd373181b;p=gcc.git final.c (final): If a label is reached only from a single jump... 0 * final.c (final): If a label is reached only from a single jump, call NOTICE_UPDATE_CC on the jump and its predecessor before emitting the insn after the label. * i386.h: Add AMD K6 support. Change TARGET_* macros to use table lookup. (INITIALIZE_TRAMPOLINE): Improve trampoline code. (ADJUST_COST): Change definition to call function in i386.c. (ISSUE_RATE): Define as 2 for anything newer than an 80486. * i386.c: Add AMD K6 support. Add constants for feature tests used by TARGET_* macros. (split_di): If before reload, call gen_lowpart and gen_highpart. (x86_adjust_cost): New function. (put_jump_code): New function. (print_operand): New codes 'D' and 'd'. * i386.md: New insn types. New insn attribute "memory". Redefine scheduling parameters to use new types and add AMD K6 support. Explicitly set type of most insns. (move insns): K6 prefers movl $0,reg to xorl reg,reg. Pentium Pro and K6 prefer movl $1,reg to incl reg. (adddi3, subdi3): Set cc_status. (DImode shift patterns): Change label counters from HOST_WIDE_INT to int; x86 can't have more than 2^31 DImode shifts per file. (setcc): Combine all setcc patterns. Allow writing memory. Combine all jump patterns using match_operator. (*bzero): Name pattern. Emit mutliple stos instructions when that is faster than rep stos. (xordi3, anddi3, iordi3): Simplify DImode logical patterns and add define_split. * ch/Make-lang.in: Comment ^L characters. Sun make doesn't like them.
