Alan Modra febda64f15 ubsan: wasm32: signed integer overflow
The signed integer overflow occurred when adding one to target_count
  for (i = 0; i < target_count + 1; i++)
but that's the least of the worries here.  target_count was long and i
int, leading to the possibility of a loop that never ended.

So to avoid this type of vulnerability, this patch uses what I believe
to be the proper types for arguments of various wasm32 opcodes, rather
than using "long" which may change in size.

gas/
	* testsuite/gas/wasm32/allinsn.d: Update expected output.
opcodes/
	* wasm32-dis.c (print_insn_wasm32): Localise variables.  Store
	result of wasm_read_leb128 in a uint64_t and check that bits
	are not lost when copying to other locals.  Use uint32_t for
	most locals.  Use PRId64 when printing int64_t.

		   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.
