_Float16 is not present on g++ #57
Comments
Is this causing a compiler error for you? I've been able to compile with float16 support on arm64. |
Never mind, I've just tried compiling again on my arm64 tester and see the issue. Thanks, I'll look into this. |
Should this be included in CI? I mean multiple compiler and compiler versions etc. |
Yeah, probably. The main reason it's not currently testing lots of compilers was to keep the Docker image small-ish. I test lots of different compilers and configs on my own machine before committing, as well as testing on ARM64 using an rpi4:
I'd like to migrate the CI to use GitHub actions and at that point I'd automate more platforms, but don't really have the time at the moment. |
