From 3e8fb15a8cfd0e62dd474af9f536863392ed7572 Mon Sep 17 00:00:00 2001 From: Joe Ramsay Date: Tue, 6 Oct 2020 07:33:52 +0100 Subject: [PATCH] arm: Add +nomve and +nomve.fp options to -mcpu=cortex-m55 This patch rearranges feature bits for MVE and FP to implement the following flags for -mcpu=cortex-m55. - +nomve: equivalent to armv8.1-m.main+fp.dp+dsp. - +nomve.fp: equivalent to armv8.1-m.main+mve+fp.dp (+dsp is implied by +mve). - +nofp: equivalent to armv8.1-m.main+mve (+dsp is implied by +mve). - +nodsp: equivalent to armv8.1-m.main+fp.dp. Combinations of the above: - +nomve+nofp: equivalent to armv8.1-m.main+dsp. - +nodsp+nofp: equivalent to armv8.1-m.main. Due to MVE and FP sharing vfp_base, some new syntax was required in the CPU description to implement the concept of 'implied bits'. These are non-named features added to the ISA late, depending on whether one or more features which depend on them are present. This means vfp_base can be present when only one of MVE and FP is removed, but absent when both are removed. gcc/ChangeLog: 2020-07-31 Joe Ramsay * config/arm/arm-cpus.in: (ALL_FPU_INTERNAL): Remove vfp_base. (VFPv2): Remove vfp_base. (MVE): Remove vfp_base. (vfp_base): Redefine as implied bit dependent on MVE or FP (cortex-m55): Add flags to disable MVE, MVE FP, FP and DSP extensions. * config/arm/arm.c (arm_configure_build_target): Add implied bits to ISA. * config/arm/parsecpu.awk: (gen_isa): Print implied bits and their dependencies to ISA header. (gen_data): Add parsing for implied feature bits. gcc/testsuite/ChangeLog: * gcc.target/arm/cortex-m55-nodsp-flag-hard.c: New test. * gcc.target/arm/cortex-m55-nodsp-flag-softfp.c: New test. * gcc.target/arm/cortex-m55-nodsp-nofp-flag-softfp.c: New test. * gcc.target/arm/cortex-m55-nofp-flag-hard.c: New test. * gcc.target/arm/cortex-m55-nofp-flag-softfp.c: New test. * gcc.target/arm/cortex-m55-nofp-nomve-flag-softfp.c: New test. * gcc.target/arm/cortex-m55-nomve-flag-hard.c: New test. * gcc.target/arm/cortex-m55-nomve-flag-softfp.c: New test. * gcc.target/arm/cortex-m55-nomve.fp-flag-hard.c: New test. * gcc.target/arm/cortex-m55-nomve.fp-flag-softfp.c: New test. * gcc.target/arm/multilib.exp: Add tests for -mcpu=cortex-m55. --- gcc/config/arm/arm-cpus.in | 26 ++++++++--- gcc/config/arm/arm.c | 14 ++++++ gcc/config/arm/parsecpu.awk | 51 ++++++++++++++++++++++ .../gcc.target/arm/cortex-m55-nodsp-flag-hard.c | 15 +++++++ .../gcc.target/arm/cortex-m55-nodsp-flag-softfp.c | 15 +++++++ .../arm/cortex-m55-nodsp-nofp-flag-softfp.c | 15 +++++++ .../gcc.target/arm/cortex-m55-nofp-flag-hard.c | 15 +++++++ .../gcc.target/arm/cortex-m55-nofp-flag-softfp.c | 15 +++++++ .../arm/cortex-m55-nofp-nomve-flag-softfp.c | 15 +++++++ .../gcc.target/arm/cortex-m55-nomve-flag-hard.c | 15 +++++++ .../gcc.target/arm/cortex-m55-nomve-flag-softfp.c | 15 +++++++ .../gcc.target/arm/cortex-m55-nomve.fp-flag-hard.c | 15 +++++++ .../arm/cortex-m55-nomve.fp-flag-softfp.c | 15 +++++++ gcc/testsuite/gcc.target/arm/multilib.exp | 16 +++++++ 14 files changed, 250 insertions(+), 7 deletions(-) create mode 100644 gcc/testsuite/gcc.target/arm/cortex-m55-nodsp-flag-hard.c create mode 100644 gcc/testsuite/gcc.target/arm/cortex-m55-nodsp-flag-softfp.c create mode 100644 gcc/testsuite/gcc.target/arm/cortex-m55-nodsp-nofp-flag-softfp.c create mode 100644 gcc/testsuite/gcc.target/arm/cortex-m55-nofp-flag-hard.c create mode 100644 gcc/testsuite/gcc.target/arm/cortex-m55-nofp-flag-softfp.c create mode 100644 gcc/testsuite/gcc.target/arm/cortex-m55-nofp-nomve-flag-softfp.c create mode 100644 gcc/testsuite/gcc.target/arm/cortex-m55-nomve-flag-hard.c create mode 100644 gcc/testsuite/gcc.target/arm/cortex-m55-nomve-flag-softfp.c create mode 100644 gcc/testsuite/gcc.target/arm/cortex-m55-nomve.fp-flag-hard.c create mode 100644 gcc/testsuite/gcc.target/arm/cortex-m55-nomve.fp-flag-softfp.c diff --git a/gcc/config/arm/arm-cpus.in b/gcc/config/arm/arm-cpus.in index 27ce000..8c61ad0 100644 --- a/gcc/config/arm/arm-cpus.in +++ b/gcc/config/arm/arm-cpus.in @@ -135,10 +135,6 @@ define feature armv8_1m_main # Floating point and Neon extensions. # VFPv1 is not supported in GCC. -# This feature bit is enabled for all VFP, MVE and -# MVE with floating point extensions. -define feature vfp_base - # Vector floating point v2. define feature vfpv2 @@ -251,7 +247,7 @@ define fgroup ALL_SIMD ALL_SIMD_INTERNAL ALL_SIMD_EXTERNAL # List of all FPU bits to strip out if -mfpu is used to override the # default. fp16 is deliberately missing from this list. -define fgroup ALL_FPU_INTERNAL vfp_base vfpv2 vfpv3 vfpv4 fpv5 fp16conv fp_dbl ALL_SIMD_INTERNAL +define fgroup ALL_FPU_INTERNAL vfpv2 vfpv3 vfpv4 fpv5 fp16conv fp_dbl ALL_SIMD_INTERNAL # Similarly, but including fp16 and other extensions that aren't part of # -mfpu support. define fgroup ALL_FPU_EXTERNAL fp16 bf16 @@ -296,11 +292,11 @@ define fgroup ARMv8r ARMv8a define fgroup ARMv8_1m_main ARMv8m_main armv8_1m_main # Useful combinations. -define fgroup VFPv2 vfp_base vfpv2 +define fgroup VFPv2 vfpv2 define fgroup VFPv3 VFPv2 vfpv3 define fgroup VFPv4 VFPv3 vfpv4 fp16conv define fgroup FPv5 VFPv4 fpv5 -define fgroup MVE mve vfp_base armv7em +define fgroup MVE mve armv7em define fgroup MVE_FP MVE FPv5 fp16 mve_float define fgroup FP_DBL fp_dbl @@ -310,6 +306,18 @@ define fgroup NEON FP_D32 neon define fgroup CRYPTO NEON crypto define fgroup DOTPROD NEON dotprod +# Implied feature bits.
