Why is -march=native not enabled by default by compilers/IDEs?
Oct 5, 2018 · For -O0, whether -march=native or -march=<generic> is the default still specifies the same family, so both are perfectly compatibly with -O0; and whenever another optimization level is specified, -march=native is beneficial to performance. So, for me, the fact that -O0 is the default doesn't matter for -march 's default.

How do I format a date in JavaScript? - Stack Overflow
You can also pull out the parts of a DateTimeFormat one-by-one using DateTimeFormat#format, but note that when using this method, as of March 2020, there is a bug in the ECMAScript implementation when it comes to leading zeros on minutes and seconds (this bug is circumvented by the approach above).
-march=haswell vs -march=core-avx2 vs -mavx2 - Stack Overflow
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. So -mavx2 is a subset of the other two. But beyond that, how do I choose the right one for my application?

gcc - How is -march different from -mtune? - Stack Overflow
Oct 12, 2024 · -march=foo implies -mtune=foo unless you also specify a different -mtune. 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 …
