- riscv cross compiler error: invalid -march= option: `rv64imafdc_zicsr
GNU assembler version 2 38 (x86_64-linux-gnu) using BFD version (GNU Binutils for Ubuntu) 2 38 Assembler messages: Fatal error: invalid -march= option: `rv64imafdc_zicsr' Thanks for any response and help! Best regards Troy
- Why is -march=native not enabled by default by compilers IDEs?
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
- -march=haswell vs -march=core-avx2 vs -mavx2 - Stack Overflow
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
-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 new enough GCC that knows about
- datetime - How to get UTC time in Python? - Stack Overflow
For Python 3, use datetime now(timezone utc) to get a timezone-aware datetime, and use timestamp() to convert it to a timestamp from datetime import datetime, timezone datetime now(timezone utc) datetime now(timezone utc) timestamp() * 1000 # POSIX timestamp in milliseconds For your purposes when you need to calculate an amount of time spent between two dates all that you need is to subtract
