Ijaz, Abdul B 9dc89f2b27 gdb: Update linkage name lookup function to allow mst_file_data/bss types.
From the commit 667ed4b14d onward, instead
of normal name GDB looks for the "jit_descriptor" linkage name in the JIT
code initialization.  Without this change, the function
"lookup_minimal_symbol_linkage", only matches the non-static data.  So in
case jit_debugger is static type then setting up breakpoint in the JIT code
fails.  Issue is seen for the intel compilers, where jit_debug_descriptor has
static type i.e. "mst_file_data".  Hence lookup_minimal_symbol_linkage returns
nullptr for it.  So, in this case breakpoint does not hit in the JIT code.
To resolve this, the commit introduces a new boolean argument to the
lookup_minimal_symbol_linkage function.  This argument allows the function to
also match mst_file_data and mst_file_bss types when set to true.  The
function is called with this new argument set to true only from JIT code
initialization handling, ensuring that the current behavior remains unchanged
for other cases.  Because handling of static types of data symbols for all cases
result in regression for "gdb.base/print-file-var.exp" test.

Example of minsym for the JIT code emitted by the intel compilers where
lookup_minimal_symbol_linkage fails without this change because jit_debugger
type is "mst_file_data".

Updated the test "jit-elf-so.exp" to test the static type of jit_descriptor
object.

		   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.
