Andrew Stubbs 4a87a8e4b1 amdgcn: Change offload variable table discovery
Up to now the libgomp GCN plugin has been finding the offload variables
by using a symbol lookup, but the AMD runtime requires that the symbols are
global for that to work. This was ensured by mkoffload as a post-procssing
step, but the LLVM 13 assembler no longer accepts this in the case where the
variable was previously declared differently.

This patch switches to locating the symbols directly from the
offload_var_table, which means that only one symbol needs to be forced
global.

This changes breaks the libgomp image compatibility so GOMP_VERSION_GCN has
also been bumped.

gcc/ChangeLog:

	* config/gcn/mkoffload.c (process_asm): Process the variable table
	completely differently.
	(process_obj): Encode the varaible data differently.

include/ChangeLog:

	* gomp-constants.h (GOMP_VERSION_GCN): Bump.

libgomp/ChangeLog:

	* plugin/plugin-gcn.c (struct gcn_image_desc): Remove global_variables.
	(GOMP_OFFLOAD_load_image): Locate the offload variables via the
	table, not individual symbols.

README

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the files whose
names start with COPYING for copying permission.  The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.

See http://gcc.gnu.org/bugs/ for how to report bugs usefully.

Copyright years on GCC source files may be listed using range
notation, e.g., 1987-2012, indicating that every year in the range,
inclusive, is a copyrightable year that could otherwise be listed
individually.
