2023-06-19avr: Fix wrong array bounds warning on SFR accessSenthil Kumar Selvaraj1-6/+0
The warning was raised on accessing SFRs at addresses below the default page size, as gcc considers accessing addresses in the first page of memory as suspicious. This doesn't apply to an embedded target like the avr, where both flash and RAM have zero as a valid address. Zero is also a valid address in named address spaces (__memx, flash<n> etc..). This commit implements TARGET_ADDR_SPACE_ZERO_ADDRESS_VALID for the avr target and reports to gcc that zero is a valid address on all address spaces. It also disables flag_delete_null_pointer_checks based on the target hook, and modifies target-supports.exp to add avr to the list of targets that always keep null pointer checks. This fixes a bunch of DejaGNU failures that occur otherwise. PR target/105523 gcc/ChangeLog: * common/config/avr/avr-common.cc: Remove setting of OPT_fdelete_null_pointer_checks. * config/avr/avr.cc (avr_option_override): Clear flag_delete_null_pointer_checks if zero_address_valid.

2023-05-08RISC-V: Handle multi-lib path correclty for linuxKito Cheng1-40/+88
RISC-V Linux encodes the ABI into the path, so in theory, we can only use that to select multi-lib paths, and no way to use different multi-lib paths between `rv32i/ilp32` and `rv32ima/ilp32`, we'll mapping both to `/lib/ilp32`. It's hard to do that with GCC's builtin multi-lib selection mechanism; builtin mechanism did the option string compare and then enumerate all possible reuse rules during the build time. However, it's impossible to RISC-V; we have a huge number of combinations of `-march`, so implementing a customized multi-lib selection becomes the only solution. Multi-lib configuration is only used for determines which ISA should be used when compiling the corresponding ABI variant after this patch. During the multi-lib selection stage, only consider -mabi as the only key to select the multi-lib path. gcc/ChangeLog: * common/config/riscv/riscv-common.cc (riscv_select_multilib_by_abi): New. (riscv_select_multilib): New. (riscv_compute_multilib): Extract logic to riscv_select_multilib and also handle select_by_abi. * config/riscv/elf.h (RISCV_USE_CUSTOMISED_MULTI_LIB): Change it to select_by_abi_arch_cmodel from 1. * config/riscv/linux.h (RISCV_USE_CUSTOMISED_MULTI_LIB): Define. * config/riscv/riscv-opts.h (enum riscv_multilib_select_kind): New.
2023-04-20i386: Share AES xmm intrin with VAESHaochen Jiang1-1/+4
Currently in GCC, the 128 bit intrin for instruction vaes{end,dec}{last,} is under AES ISA. Because there is no dependency between ISA set AES and VAES, The 128 bit intrin is not available when we use compiler flag -mvaes -mavx512vl and there is no other way to use that intrin. But it should according to Intel SDM. Although VAES aims to be a VEX/EVEX promotion for AES, but it is only part of it. Therefore, we share the AES xmm intrin with VAES. Also, since -mvaes indicates that we could use VEX encoding for ymm, we should imply AVX for VAES. gcc/ChangeLog: * common/config/i386/i386-common.cc (OPTION_MASK_ISA2_AVX_UNSET): Add OPTION_MASK_ISA2_VAES_UNSET. (ix86_handle_option): Set AVX flag for VAES. * config/i386/i386-builtins.cc (ix86_init_mmx_sse_builtins): Add OPTION_MASK_ISA2_VAES_UNSET.

2023-04-20i386: Add PCLMUL dependency for VPCLMULQDQHaochen Jiang1-3/+6
Currently in GCC, the 128 bit intrin for instruction vpclmulqdq is under PCLMUL ISA. Because there is no dependency between ISA set PCLMUL and VPCLMULQDQ, The 128 bit intrin is not available when we just use compiler flag -mvpclmulqdq. But it should according to Intel SDM. Since VPCLMULQDQ is a VEX/EVEX promotion for PCLMUL, it is natural to add dependency between them. Also, with -mvpclmulqdq, we can use ymm under VEX encoding, so VPCLMULQDQ should imply AVX. gcc/ChangeLog: * common/config/i386/i386-common.cc (OPTION_MASK_ISA_VPCLMULQDQ_SET): Add OPTION_MASK_ISA_PCLMUL_SET and OPTION_MASK_ISA_AVX_SET.

2023-02-09i386: Call get_available_features for all CPUs with max_level >= 1 [PR100758]Jakub Jelinek1-16/+9
get_available_features doesn't depend on cpu_model2->__cpu_{family,model} and just sets stuff up based on CPUID leaf 1, or some extended ones, so I wonder why are we calling it separately for Intel, AMD and Zhaoxin and not for all other CPUs too? I think various programs in the wild which aren't using __builtin_cpu_{is,supports} just check the various CPUID leafs and query bits in there, without blacklisting unknown CPU vendors, so I think even __builtin_cpu_supports ("sse2") etc. should be reliable if those VENDOR_{CENTAUR,CYRIX,NSC,OTHER} CPUs set those bits in CPUID leaf 1 or some extended ones. Calling it for all CPUs also means it can be inlined because there will be just a single caller. I have tested it on Intel and Martin tested it on AMD, but can't test it on non-Intel/AMD; for Intel/AMD/Zhaoxin it should be really no change in behavior. 2023-02-09 Jakub Jelinek <jakub@redhat.com> PR target/100758 * common/config/i386/cpuinfo.h (get_zhaoxin_cpu): Formatting fixes.

2023-02-01AArch64: Fix native detection in the presence of mandatory features which ↵Tamar Christina1-5/+17
don't have midr values aarch64-option-extensions.def explicitly defines the semantics for an empty midr field as being: In that case this field should contain a space (" ") separated list of the strings in 'Features' that are required. Their order is not important. An empty string means do not detect this feature during auto detection. That is to say, an empty string means that we don't know the midr value for this feature and so it just shouldn't be taken into account for native features detection. However this meaning seems to have gotten lost at some point. This results in e.g. -mcpu=native on a Neoverse N2 disabling features it does have. Essentially we disabled any mandatory feature for which there is no midr entry. The rationale for having -mcpu=native being able to disable features at all, is because the kernel is able to disable a mandatory feature for correctness issues. Unfortunately we can't distinguish between "old kernel" and "kernel disabled". This patch adds a new field that indicates whether the midr field has any value at all. If there's no value we skip the extension when determining the "off" flags. gcc/ChangeLog: * common/config/aarch64/aarch64-common.cc (struct aarch64_option_extension): Add native_detect and document struct a bit more.

2023-01-23[PATCH 1/15] arm: Make mbranch-protection opts parsing common to AArch32/64Andrea Corallo1-6/+7
Hi all, This change refactors all the mbranch-protection option parsing code and types to make it common to both AArch32 and AArch64 backends. This change also pulls in some supporting types from AArch64 to make it common (aarch_parse_opt_result). The significant changes in this patch are the movement of all branch protection parsing routines from aarch64.c to aarch-common.c and supporting data types and static data structures. This patch also pre-declares variables and types required in the aarch32 back-end for moved variables for function sign scope and key to prepare for the impending series of patches that support parsing the feature mbranch-protection in the aarch32 back-end. gcc/ChangeLog: * common/config/aarch64/aarch64-common.cc: Include aarch-common.h.

2022-12-27rs6000: Rework option -mpowerpc64 handling [PR106680]Kewen Lin1-11/+0
PR106680 shows that -m32 -mpowerpc64 is different from -mpowerpc64 -m32, this is determined by the way how we handle option powerpc64 in rs6000_handle_option. Segher pointed out this difference should be taken as a bug and we should ensure that option powerpc64 is independent of -m32/-m64. So this patch removes the handlings in rs6000_handle_option and add some necessary supports in rs6000_option_override_internal instead. With this patch, if users specify -m{no-,}powerpc64, the specified value is honoured, otherwise, for 64bit it always enables OPTION_MASK_POWERPC64; while for 32bit and TARGET_POWERPC64 and OS_MISSING_POWERPC64, it disables OPTION_MASK_POWERPC64. btw, following Segher's suggestion, I did some tries to warn when OPTION_MASK_POWERPC64 is set for OS_MISSING_POWERPC64. If warn for the case that powerpc64 is specified explicitly, there are some TCs using -m32 -mpowerpc64 on ppc64-linux, they need some updates, meanwhile the artificial run with "--target_board=unix'{-m32/-mpowerpc64}'" will have noisy warnings on ppc64-linux. If warn for the case that it's specified implicitly, they can just be initialized by TARGET_DEFAULT (like -m32 on ppc64-linux) or set from the given cpu mask, we have to special case them and not to warn. As Segher's latest comment, I decide not to warn them and keep it consistent with before. Bootstrapped and regress-tested on: - powerpc64-linux-gnu P7 and P8 {-m64,-m32} - powerpc64le-linux-gnu P9 and P10 - powerpc-ibm-aix7.2.0.0 {-maix64,-maix32} - powerpc-darwin9 (with Iain's help) PR target/106680 gcc/ChangeLog: * common/config/rs6000/rs6000-common.cc (rs6000_handle_option): Remove the adjustment for option powerpc64 in -m64 handling, and remove the whole -m32 handling. * config/rs6000/rs6000.cc (rs6000_option_override_internal): When no explicit powerpc64 option is provided, enable it for -m64.

2022-11-14Enable small loop unrolling for O2Hongyu Wang1-0/+1
Modern processors has multiple way instruction decoders For x86, icelake/zen3 has 5 uops, so for small loop with <= 4 instructions (usually has 3 uops with a cmp/jmp pair that can be macro-fused), the decoder would have 2 uops bubble for each iteration and the pipeline could not be fully utilized. Therefore, this patch enables loop unrolling for small size loop at O2 to fullfill the decoder as much as possible. It turns on rtl loop unrolling when targetm.loop_unroll_adjust exists and O2 plus speed only. In x86 backend the default behavior is to unroll small loops with less than 4 insns by 1 time. This improves 548.exchange2 by 9% on icelake and 7.4% on zen3 with 0.9% codesize increment. For other benchmarks the variants are minor and overall codesize increased by 0.2%.
