ARC: Use new definitions for optional ARC CPU features
GCC for ARC has been updated to provide consistent naming of preprocessor definitions for different optional architecture features: * __ARC_BARREL_SHIFTER__ instead of __Xbarrel_shifter for -mbarrel-shifter * __ARC_LL64__ instead of __LL64__ for -mll64 * __ARCEM__ instead of __EM__ for -mcpu=arcem * __ARCHS__ instead of __HS__ for -mcpu=archs * etc (not used in newlib) This patch updates assembly routines for ARC to use new definitions instead of a deprecated ones. To ensure compatibility with older compiler new definitions are also defined in asm.h if needed, based on deprecated preprocessor definitions. *** newlib/ChangeLog *** 2015-12-15 Anton Kolesov <Anton.Kolesov@synopsys.com> * libc/machine/arc/asm.h: Define new GCC definition for old compiler. * libc/machine/arc/memcmp-bs-norm.S: Use new GCC defines to detect processor features. * libc/machine/arc/memcmp.S: Likewise. * libc/machine/arc/memcpy-archs.S: Likewise. * libc/machine/arc/memcpy-bs.S: Likewise. * libc/machine/arc/memcpy.S: Likewise. * libc/machine/arc/memset-archs.S: Likewise. * libc/machine/arc/memset-bs.S: Likewise. * libc/machine/arc/memset.S: Likewise. * libc/machine/arc/setjmp.S: Likewise. * libc/machine/arc/strchr-bs-norm.S: Likewise. * libc/machine/arc/strchr-bs.S: Likewise. * libc/machine/arc/strchr.S: Likewise. * libc/machine/arc/strcmp-archs.S: Likewise. * libc/machine/arc/strcmp.S: Likewise. * libc/machine/arc/strcpy-bs-arc600.S: Likewise. * libc/machine/arc/strcpy-bs.S: Likewise. * libc/machine/arc/strcpy.S: Likewise. * libc/machine/arc/strlen-bs-norm.S: Likewise. * libc/machine/arc/strlen-bs.S: Likewise. * libc/machine/arc/strlen.S: Likewise. * libc/machine/arc/strncpy-bs.S: Likewise. * libc/machine/arc/strncpy.S: Likewise.

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.
