So, for me, the fact that -O0 is the default doesn't matter for -march 's default.Fri, 24 Apr 2026 23:28:00 GMThttps://stackoverflow.com/questions/63922720/gcc-differences-between-march-native-and-march-specific-archHow does -march=native choose which instruction sets to enable and which to disable? I have the following conjecture: -march=native will be using CPUID instructions to calculate supported instruction sets etc in order to detect the processor variant -march=foobar will use a hardcoded list of instruction sets which processor foobar supports.Mon, 20 Apr 2026 02:18:00 GMThttps://stackoverflow.com/questions/77765315/equivalent-of-march-native-for-msvcAs far as I know, the compilation option for MSVC that tells the compiler to use special available instruction is /arch. On clang/linux, we can use -march=native to automatically detect the archite...Fri, 24 Apr 2026 16:25:00 GMThttps://stackoverflow.com/questions/73142229/march-haswell-vs-march-core-avx2-vs-mavx2What 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. So -mavx2 is a subset of the other two. But beyond that, how do I choose the right one for my application?Thu, 23 Apr 2026 15:08:00 GMThttps://stackoverflow.com/questions/79626441/cannot-find-suitable-multilib-set-for-march-rv32imafd-zicntr-zicsr-zifenceiWhen I configured and make the GCC by " sudo ../configure --prefix=/opt/riscv --target=riscv32-unknown-elf --disable-multilib --with-multilib-generator="rv32gc_zicntr ...Fri, 24 Apr 2026 02:28:00 GMThttps://stackoverflow.com/questions/68145157/unrecognized-command-line-option-arch-did-you-mean-marchunrecognized command-line option '-arch'; did you mean '-march='?

This is one reason why using -march is better than just enabling options like -mavx without doing anything about tuning. 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. Use a new enough GCC that knows about ...Mon, 20 Apr 2026 12:05:00 GMThttps://stackoverflow.com/questions/79500994/how-to-know-all-supported-values-for-clang-march-argumentUsing Clang 16.0 or later, I would like to know what values could be used for the -march argument. The command clang --print-supported-cpus shows for -mcpu=, but I see no alternative for -march.Tue, 21 Apr 2026 12:11:00 GMThttps://stackoverflow.com/questions/77540319/how-to-change-march-native-compile-flag-added-by-pcl-in-cmake"I want change it to -march=x86-64 in cmake, How to do it? - Find out how exactly PCL adds -march=native flag. If it does that via variable CMAKE_CXX_FLAGS, then you may try to modify that variable (but note about variables scoping rules). If PCL adds the flag to some property, then you may try modify that property. CMake doesn't give you a control over combined compiler flags. You need to ...Tue, 21 Apr 2026 08:44:00 GMT
