( * 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. From-SVN: r22292 |

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
