Accept the architecture configure option and resolve build failures. This is enough to build binaries, but I've not got a device to test it on, so there are probably runtime issues to fix. The cache control instructions might be unsafe (or too conservative), and the kernel metadata might be off. Vector reductions will need to be reworked for RDNA2. In principle, it would be better to use wavefrontsize32 for this architecture, but that would mean switching everything to allow SImode masks, so wavefrontsize64 it is. The multilib is not included in the default configuration so either configure --with-arch=gfx1030 or include it in --with-multilib-list=gfx1030,.... The majority of this patch has no effect on other devices, but changing from using scalar writes for the exit value to vector writes means we don't need the scalar cache write-back instruction anywhere (which doesn't exist in RDNA2). gcc/ChangeLog: * config.gcc: Allow --with-arch=gfx1030. * config/gcn/gcn-hsa.h (NO_XNACK): gfx1030 does not support xnack.

(gcn_global_address_p): RDNA2 only allows smaller offsets. (gcn_addr_space_legitimate_address_p): Likewise. (gcn_omp_device_kind_arch_isa): Recognise gfx1030. (gcn_expand_epilogue): Use VGPRs instead of SGPRs.

(mulsi3): v_mul_lo_i32 should be v_mul_lo_u32 on all ISA. (*memory_barrier): Add RDNA2 syntax variant. (atomic_load<mode>): Add RDNA2 cache control variants, and disable scalar atomics for RDNA2. (atomic_store<mode>): Likewise. (atomic_exchange<mode>): Likewise. * config/gcn/gcn.opt (gpu_type): Add gfx1030. * config/gcn/mkoffload.cc (EF_AMDGPU_MACH_AMDGCN_GFX1030): New.

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.
