#51642: GCC does not honor -march=native ------------------------+-------------------------------- Reporter: noloader@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Keywords: | Port: ------------------------+-------------------------------- I'm attempting a compile uder MacPort's GCC compiler: {{{ $ make CXX=/opt/local//bin/x86_64-apple-darwin12-gcc-4.9.3 /opt/local//bin/x86_64-apple-darwin12-gcc-4.9.3 -DNDEBUG -g2 -O2 -fPIC -march=native -pipe -c cryptlib.cpp :1057:no such instruction: `vzeroupper' :1507:no such instruction: `vzeroupper' :1517:no such instruction: `vzeroupper' :1662:no such instruction: `vzeroupper' :1838:no such instruction: `vzeroupper' ... }}} Piping it into `wc` reveals: {{{ $ make CXX=/opt/local//bin/x86_64-apple-darwin12-gcc-4.9.3 2>&1 | wc -l 190 }}} The machine is a 2012 MacBook Pro with a Core i7-2760QM. Broadly speaking, the cpu includes SSE4 and AES-NI, but lacks RDRAND and RDSEED: {{{ $ sysctl -a | grep machdep.cpu.features machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT PSE36 CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM PBE SSE3 PCLMULQDQ DTES64 MON DSCPL VMX SMX EST TM2 SSSE3 CX16 TPR PDCM SSE4.1 SSE4.2 x2APIC POPCNT AES PCID XSAVE OSXSAVE TSCTMR AVX1.0 }}} `vzeroupper` is part of AVX, and AVX is available in the cpu feature set. We have users who use a few MacPorts compilers, so I'm guessing additional testing will reveal the same issue under GCC 5.1 and 5.3. I'm only going to file this one report, however. ----- Here's some additional information that may be useful. {{{ $ port version Version: 2.3.4 }}} And: {{{ $ sysctl -a | grep machdep.cpu machdep.cpu.max_basic: 13 machdep.cpu.max_ext: 2147483656 machdep.cpu.vendor: GenuineIntel machdep.cpu.brand_string: Intel(R) Core(TM) i7-2760QM CPU @ 2.40GHz machdep.cpu.family: 6 machdep.cpu.model: 42 machdep.cpu.extmodel: 2 machdep.cpu.extfamily: 0 machdep.cpu.stepping: 7 machdep.cpu.feature_bits: 3219913727 532341759 machdep.cpu.extfeature_bits: 672139520 1 machdep.cpu.signature: 132775 machdep.cpu.brand: 0 machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT PSE36 CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM PBE SSE3 PCLMULQDQ DTES64 MON DSCPL VMX SMX EST TM2 SSSE3 CX16 TPR PDCM SSE4.1 SSE4.2 x2APIC POPCNT AES PCID XSAVE OSXSAVE TSCTMR AVX1.0 machdep.cpu.extfeatures: SYSCALL XD EM64T LAHF RDTSCP TSCI machdep.cpu.logical_per_package: 16 machdep.cpu.cores_per_package: 8 machdep.cpu.microcode_version: 26 machdep.cpu.processor_flag: 4 machdep.cpu.mwait.linesize_min: 64 machdep.cpu.mwait.linesize_max: 64 machdep.cpu.mwait.extensions: 3 machdep.cpu.mwait.sub_Cstates: 135456 machdep.cpu.thermal.sensor: 1 machdep.cpu.thermal.dynamic_acceleration: 1 machdep.cpu.thermal.invariant_APIC_timer: 1 machdep.cpu.thermal.thresholds: 2 machdep.cpu.thermal.ACNT_MCNT: 1 machdep.cpu.thermal.core_power_limits: 1 machdep.cpu.thermal.fine_grain_clock_mod: 1 machdep.cpu.thermal.package_thermal_intr: 1 machdep.cpu.thermal.hardware_feedback: 0 machdep.cpu.thermal.energy_policy: 0 machdep.cpu.xsave.extended_state: 7 832 832 0 machdep.cpu.arch_perf.version: 3 machdep.cpu.arch_perf.number: 4 machdep.cpu.arch_perf.width: 48 machdep.cpu.arch_perf.events_number: 7 machdep.cpu.arch_perf.events: 0 machdep.cpu.arch_perf.fixed_number: 3 machdep.cpu.arch_perf.fixed_width: 48 machdep.cpu.cache.linesize: 64 machdep.cpu.cache.L2_associativity: 8 machdep.cpu.cache.size: 256 machdep.cpu.tlb.inst.small: 64 machdep.cpu.tlb.inst.large: 8 machdep.cpu.tlb.data.small: 64 machdep.cpu.tlb.data.large: 32 machdep.cpu.tlb.shared: 512 machdep.cpu.address_bits.physical: 36 machdep.cpu.address_bits.virtual: 48 machdep.cpu.core_count: 4 machdep.cpu.thread_count: 8 }}} -- Ticket URL: <https://trac.macports.org/ticket/51642> MacPorts <https://www.macports.org/> Ports system for OS X
