Whilst reviewing Luis' proposed change to s_arm_unwind_save_mixed yesterday I noticed that we were making use of __builting_clzl directly within the main function, which is not guaranteed to be portable. Whilst studying the code further, I also realized that it could be rewritten without using it and also reworked to remove a lot of unnecessary iterations steps. So this patch does that (and also removes the source of the warning that Luis was trying to fix). Finally, with the rewrite we can also simplify the caller of this routine as the new version can handle all the cases directly. * config/tc-arm.c (s_arm_unwind_save_mixed): Rewrite without using __builtin_clzl. (s_arm_unwind_save): Simplify logic for simple/mixed register saves.

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.
