�
* 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.
