A review comment on the SCFI V4 series was to bail out on APX
instructions differently:
Currently, GAS bails out at the mere sight of an APX instruction when
--scfi=experimental is in effect; this is implemented in form of an
early exit from x86_ginsn_new (). It is preferable to not have to
handle APX instructions explicitly like that with an early exit,
but rather to use the existing infrastructure in the x86_ginsn_new ()
function to bail out only if the APX insn affects SCFI correctness.
FIXME -
1. There remains an outstanding issue with adcx etc ops
2. Add tests once above is fixed

* config/tc-i386.c (ginsn_opsize_prefix_p): Rename and adjust to
be ginsn_implicitstackop_opsize16_p instead.
(x86_ginsn_enter): Use the new function.
(x86_ginsn_leave): Likewise.
(x86_ginsn_new): Likewise. Also remove the stub for early exit
for APX instructions.

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.
