It looks like an oversight to me. If there are no "skylake-avx512" model, then the driver goes through "This is unknown ..." for -march=native and hopefully chooses the next most appropriate choice. Please add "skylake-avx512" in a follow-up patch. > Thanks, > Julia > > gcc/ > * config.gcc: Add -march=cannonlake. > * config/i386/driver-i386.c (host_detect_local_cpu): Detect > cannonlake. > * config/i386/i386-c.c (ix86_target_macros_internal): Handle > cannonlake. > * config/i386/i386.c (processor_costs): Add m_CANNONLAKE. > (PTA_CANNONLAKE): New. > (processor_target_table): Add cannonlake. > (ix86_option_override_internal): Ditto. > (fold_builtin_cpu): Ditto. > (get_builtin_code_for_version): Handle cannonlake. > (M_INTEL_COREI7_CANNONLAKE): New. > * config/i386/i386.h (TARGET_CANNONLAKE, PROCESSOR_CANNONLAKE): New. > * doc/invoke.texi: Add -march=cannonlake. > gcc/testsuite/ > * gcc.target/i386/funcspec-56.inc: Handle new march. > * g++.dg/ext/mv16.C: Ditto. > libgcc/ > * config/i386/cpuinfo.c (get_intel_cpu): Handle cannonlake. > * config/i386/cpuinfo.h (processor_subtypes): Add > INTEL_COREI7_CANNONLAKE. OK. Thanks, Uros.
