Almost all device-specific settings are now centralised into gcn-devices.def for the compiler, mkoffload, and libgomp. No longer will we have to touch 10 files in multiple places just to add another device without any exotic features. (New ISAs and devices with incompatible metadata will continue to need a bit more.) In order to remove the device-specific conditionals in the code a new value HSACO_ATTR_UNSUPPORTED has been added, indicating that the assembler will reject any setting of that option. This incorporates some of Tobias's patch from March 2024. Co-Authored-By: Tobias Burnus <tburnus@baylibre.com> gcc/ChangeLog: * config.gcc (amdgcn): Add gcn-device-macros.h to tm_file.

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.
