Nick Alcock b62d5edd0a libctf: fix handling of CTF symtypetab sections emitted by older GCC
Older (pre-upstreaming) GCC emits a function symtypetab section of a
format never read by any extant libctf.  We can detect such CTF dicts by
the lack of the CTF_F_NEWFUNCINFO flag in their header, and we do so
when reading in the symtypetab section -- but if the set of symbols with
types is sufficiently sparse, even an older GCC will emit a function
index section.

In NEWFUNCINFO-capable compilers, this section will always be the exact
same length as the corresponding function section (each is an array of
uint32_t, associated 1:1 with each other). But this is not true for the
older compiler, for which the sections are different lengths.  We check
to see if the function symtypetab section and its index are the same
length, but we fail to skip this check when this is not a NEWFUNCINFO
dict, and emit a spurious corruption error for a CTF dict we could
have perfectly well opened and used.

Fix trivial: check the flag (and fix the terrible grammar of the error
message at the same time).

2021-09-27  Nick Alcock  <nick.alcock@oracle.com>

	* ctf-open.c (ctf_bufopen_internal): Don't complain about corrupt
	function index symtypetab sections if this is an old-format
	function symtypetab section (which should be ignored in any case).
	Fix bad grammar.

		   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.
