Indu Bhagat c27e4f66fa gas: testsuite: add an x86 testsuite for SCFI
The testsuite for SCFI contains target-specific tests.

When a test is executed with --scfi=experimental command line option,
the CFI annotations in the test .s files are skipped altogether by the
GAS for processing.  The CFI directives in the input assembly files are,
however, validated by running the assembler one more time without
--scfi=experimental.

Some testcases are used to highlight those asm constructs that the SCFI
machinery in GAS currently does not support:

  - Only System V AMD64 ABI is supported for now. Using either --32 or
    --x32 with SCFI results in hard error.
    See scfi-unsupported-1.s.

  - Untraceable stack-pointer manipulation in function epilougue and prologue.
    See scfi-unsupported-2.s.

  - Using Dynamically Realigned Arguement Pointer (DRAP) register to
    realign the stack.  For SCFI, the CFA must be only REG_SP or REG_FP
    based.  See scfi-unsupported-drap-1.s

Some testcases are used to highlight some diagnostics that the SCFI
machinery in GAS currently issues, with an intent to help user correct
inadvertent errors in their hand-written asm.  An error is issued when
GAS finds that input asm is not amenable to correct CFI synthesis.

  - (#1) "Warning: SCFI: Asymetrical register restore"
  - (#2) "Error: SCFI: usage of REG_FP as scratch not supported"
  - (#3) "Error: SCFI: unsupported stack manipulation pattern"

In case of (#2) and (#3), SCFI generation is skipped for the respective
function.  Above is a subset of the warnings/errors implemented in the
code.

		   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.
