2021-08-24nvptx: Add a __PTX_SM__ predefined macro based on target ISA.Roger Sayle1-0/+2
This patch adds a __PTX_SM__ predefined macro to the nvptx backend that allows code to check the compute model being targeted by the compiler. This is equivalent to the __CUDA_ARCH__ macro defined by CUDA's nvcc compiler, but to avoid causing problems for source code that checks for that compiler, this macro uses GCC's nomenclature; it's easy enough for users to "#define __CUDA_ARCH__ __PTX_SM__". What might have been a four line patch is actually a little more complicated, as this patch takes the opportunity to upgrade the nvptx backend to use the now preferred nvptx-c.c idiom. 2021-08-24 Roger Sayle <roger@nextmovesoftware.com> Tom de Vries <tdevries@suse.de> gcc/ChangeLog * config.gcc (nvptx-*-*): Define {c,c++}_target_objs. * config/nvptx/nvptx-protos.h (nvptx_cpu_cpp_builtins): Prototype. * config/nvptx/nvptx.h (TARGET_CPU_CPP_BUILTINS): Implement with a call to the new nvptx_cpu_cpp_builtins function in nvptx-c.c. * config/nvptx/t-nvptx (nvptx-c.o): New rule. * config/nvptx/nvptx-c.c: New source file.

2021-01-15aarch64: Add a minipass for fusing CC insns [PR88836]Richard Sandiford1-1/+1
This patch adds a small target-specific pass to remove redundant SVE PTEST instructions. There are two important uses of this: - Removing PTESTs after WHILELOs (PR88836). The original testcase no longer exhibits the problem due to more recent optimisations, but it can still be seen in simple cases like the one in the patch. It also shows up in 450.soplex. - Removing PTESTs after RDFFRs in ACLE code. This is just an interim “solution” for GCC 11. I hope to replace it with something generic and target-independent for GCC 12. However, the use cases above are very important for performance, so I'd rather not leave the bug unfixed for yet another release cycle. Since the pass is intended to be short-lived, I've not added a command-line option for it. The pass can be disabled using -fdisable-rtl-cc_fusion if necessary. Although what the pass does is independent of SVE, it's motivated only by SVE cases and doesn't trigger for any non-SVE test I've seen. I've therefore gated it on TARGET_SVE and restricted it to PTEST patterns. gcc/ PR target/88836 * config.gcc (aarch64*-*-*): Add aarch64-cc-fusion.o to extra_objs. * Makefile.in (RTL_SSA_H): New variable. * config/aarch64/t-aarch64 (aarch64-cc-fusion.o): New rule. * config/aarch64/aarch64-protos.h (make_pass_cc_fusion): Declare. * config/aarch64/aarch64-passes.def: Add pass_cc_fusion after pass_combine. * config/aarch64/aarch64-cc-fusion.cc: New file. gcc/testsuite/ PR target/88836 * gcc.target/aarch64/sve/acle/general/ldff1_8.c: New test. * gcc.target/aarch64/sve/ptest_1.c: Likewise.

2020-12-15i386: Make -march=x86-64-v[234] behave more like other -march= optionsJakub Jelinek1-3/+1
If somebody has -march=x86-64-v2 (or -v3 or -v4) in $CFLAGS, $CXXFLAGS etc., then -m32 or -mabi=ms stops working. What is worse, if one configures gcc --with-arch-64=x86-64-v2 (or -v3 or -v4), then -mabi=ms stops working. I think that is a nightmare user experience. It is ok that x86-64-v[234] behave slightly different from other -march= options (in that they imply unless overridden -mtune=generic rather then -mtune= equal to the -march argument), but the error when one mixes it with -mabi=ms, or -m32 doesn't improve anything. It is true that the exact option set is only defined in the x86-64 psABI (IMHO that is a mistake too, we should copy that into the GCC documentation like we document it for any other -march= option), but there is no reason why that exact set of CPU features can't be used for other ABIs, it is just a set of CPU features. If we add micro-architecture levels to the 32-bit ABI (I doubt anyone wants to do that, but just hypothetically), then those micro-architecture levels wouldn't certainly be called x86-64-v* but perhaps i386-v*. In the tests, __GCC_HAVE_SYNC_COMPARE_AND_SWAP_16 can't be expected on -m32 not because the CPU feature wouldn't be set, but because the instruction is 64-bit only and 32-bit code doesn't have __int128 etc. support. 2020-12-15 Jakub Jelinek <jakub@redhat.com> * config/i386/i386-options.c (ix86_option_override_internal): Don't error on -march=x86-64-v[234] with -m32 or -mabi=ms. * config.gcc: Don't reject --with-arch=x86-64-v[234] or --with-arch_32=x86-64-v[234]. * doc/invoke.texi (-march=x86-64-v[234]): Document what the option does for other ABIs. * gcc.target/i386/x86-64-v2.c: Don't expect __GCC_HAVE_SYNC_COMPARE_AND_SWAP_16 to be defined with -m32. * gcc.target/i386/x86-64-v2-other.c: New test. * gcc.target/i386/x86-64-v2-msabi.c: New test. * gcc.target/i386/x86-64-v3.c: Fix a comment pasto.
