Indu Bhagat ce9a87252c sframe: bfd: gas: ld: format bump to SFrame version 2
SFrame version 2 encodes the size of repetitive insn block explicitly
in the format.  Add information in the SFrame FDE to convey the size
of the block of repeating instructions.  This information is used only
for SFrame FDEs of type SFRAME_FDE_TYPE_PCMASK.

Introduce two extra bytes for padding: this ensures that the memory
accesses to the members of the SFrame Frame Descriptor Entry (FDE) are
naturally aligned.

gas generates SFrame section with version SFRAME_VERSION_2 by default.

libsframe provides two new APIs to:
  - get an SFrame FDE data from the decoder context, and
  - add an SFrame FDE to the encoder context.
The additional argument (for rep_block_size) is useful for SFrame FDEs
where FDE type is SFRAME_FDE_TYPE_PCMASK.

The linker will generate the output SFrame sections in the
SFRAME_VERSION_2 format.  If the input sections offered to the linker
are not all in the SFRAME_VERSION_2 format, the linker issues an error
to the user.

objdump/readelf will show the following message to the user if .sframe
section in SFRAME_VERSION_1 format is seen:

 "No further information can be displayed.  SFrame version not
 supported."

In other words, like the rest of the binutils, only the current SFrame
format version, i.e., SFRAME_VERSION_2 is supported by the textual dump
facilities.

		   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.
