GCC modified for the FreeChainXenon project

The HSA/ROCm runtime rejects binaries not built for the exact GPU device present. So far, the libgomp amdgcn plugin does not verify that the GPU ISA and the ISA specified at compile time match before handing over the binary to the runtime. In case of a mismatch, the user is confronted with an unhelpful runtime error. This commit implements a runtime ISA check. In case of an ISA mismatch, the execution is aborted with a clear error message and a hint at the correct compilation parameters for the GPU on which the execution has been attempted. libgomp/ * plugin/plugin-gcn.c (EF_AMDGPU_MACH): New enum. * (EF_AMDGPU_MACH_MASK): New constant. * (gcn_isa): New typedef. * (gcn_gfx801_s): New constant. * (gcn_gfx803_s): New constant. * (gcn_gfx900_s): New constant. * (gcn_gfx906_s): New constant. * (gcn_isa_name_len): New constant. * (elf_gcn_isa_field): New function. * (isa_hsa_name): New function. * (isa_gcc_name): New function. * (isa_code): New function. * (struct agent_info): Add field "device_isa" and remove field "gfx900_p". * (GOMP_OFFLOAD_init_device): Adapt agent init to "agent_info" field changes, fail if device has unknown ISA. * (parse_target_attributes): Replace "gfx900_p" by "device_isa". * (isa_matches_agent): New function ... * (create_and_finalize_hsa_program): ... used from here to check that the GPU ISA and the code-object ISA match. |

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.
