g. -march Jul 27, 2022 · What are the differences and tradeoffs between -march=haswell, -march=core-avx2, and -mavx2 for compiling avx2 intrinsics? I know that -mavx2 is a flag and -march=haswell/core-avx2 are architectures which just translate to a bunch of flags. 2 and above support -march=native. So -mavx2 is a subset of the other two. As far as I know, the compilation option for MSVC that tells the compiler to use special available instruction is /arch. CMake doesn't give you a control over combined compiler flags. Troy. Caveat: -march=native on a CPU that GCC doesn't specifically recognize will still enable new instruction sets that GCC can detect, but will leave -mtune=generic. 38 Assembler messages: Fatal error: invalid -march= option: `rv64imafdc_zicsr' Thanks for any response and help! Best regards. Oct 12, 2024 · -march=foo implies -mtune=foo unless you also specify a different -mtune.
