So, for me, the fact that -O0 is the default doesn't matter for -march 's default.Mon, 06 Apr 2026 08:18:00 GMThttps://stackoverflow.com/questions/63922720/gcc-differences-between-march-native-and-march-specific-archAs I understand it, -march=native will detect the ISA and extensions to use from cpuid (which include model, family and stepping information). -march=xxx will use a baseline set of extensions and a baseline ISA. There are a lot of possible combinations of extensions, so only the most relevant were chosen (e.g. skylake-avx512 was added to reflect an important extension of some skylakes). -march ...Sat, 04 Apr 2026 18:58:00 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, 09 Apr 2026 00:58:00 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 ...Sat, 11 Apr 2026 01:17:00 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.

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 ...Sat, 04 Apr 2026 06:33:00 GMT
