This adds architecture options and multilibs for the AMD GFX90a GPUs. It also tidies up some of the ISA selection code, and corrects a few small mistake in the gfx908 naming. gcc/ChangeLog: * config.gcc (amdgcn): Accept --with-arch=gfx908 and gfx90a. * config/gcn/gcn-opts.h (enum gcn_isa): New. (TARGET_GCN3): Use enum gcn_isa. (TARGET_GCN3_PLUS): Likewise. (TARGET_GCN5): Likewise. (TARGET_GCN5_PLUS): Likewise. (TARGET_CDNA1): New. (TARGET_CDNA1_PLUS): New. (TARGET_CDNA2): New. (TARGET_CDNA2_PLUS): New. (TARGET_M0_LDS_LIMIT): New. (TARGET_PACKED_WORK_ITEMS): New. * config/gcn/gcn.cc (gcn_isa): Change to enum gcn_isa. (gcn_option_override): Recognise CDNA ISA variants. (gcn_omp_device_kind_arch_isa): Support gfx90a. (gcn_expand_prologue): Make m0 init optional. Add support for packed work items. (output_file_start): Support gfx90a. (gcn_hsa_declare_function_name): Support gfx90a metadata. * config/gcn/gcn.h (TARGET_CPU_CPP_BUILTINS):Add __CDNA1__ and __CDNA2__. * config/gcn/gcn.md (<su>mulsi3_highpart): Use TARGET_GCN5_PLUS. (<su>mulsi3_highpart_imm): Likewise. (<su>mulsidi3): Likewise. (<su>mulsidi3_imm): Likewise. * config/gcn/gcn.opt (gpu_type): Add gfx90a. * config/gcn/mkoffload.cc (EF_AMDGPU_MACH_AMDGCN_GFX90a): New. (main): Support gfx90a. * config/gcn/t-gcn-hsa: Add gfx90a multilib. * config/gcn/t-omp-device: Add gfx90a isa. libgomp/ChangeLog: * plugin/plugin-gcn.c (EF_AMDGPU_MACH): Add EF_AMDGPU_MACH_AMDGCN_GFX90a. (gcn_gfx90a_s): New. (isa_hsa_name): Support gfx90a. (isa_code): Likewise. |
