Enable fat library by default on AMD64, ARM64 and ARM(v7) as this makes libnettle include multiple versions of certain functions in the library and select the ones to use at run-time. This enables various instructions such as AES-NI on AMD64 and allows libnettle to use NEON when possible on ARM. Also set TEST_TARGET so "make test" runs as expected.

I forgot to mention that I moved USES variable to make portlint happy, sorry about that.

@Fukang Can you assist with ARM poudriere confirmation?

I missed the fact that the configure script isn't arm64/aarch64 aware while the code does take 64-bit platforms into account.


I also tried to modify the configure script to include assembly code (files) on aarch64 however that resulted in compliation errors so I think we have to settle for amd64 and arm(v7) for now. My apologies for not noticing it earlier.

This revision doesn't enable fat library on arm64/aarch64

I'll add OPTIONS_DEFINE_{am64,armv7}=FAT instead of adding FAT to OPTIONS_DEFINE since we can only build fat library on those 2 architectures currently.

FAT_DESC=       Build fat library

How is that supposed to work for us? The runtime cpu detection seems specific for linux: https://git.lysator.liu.se/nettle/nettle/blob/nettle_3.5.1_release_20190627/fat-arm.c#L64

Closing this for now, I don't have time to look into this further. Sorry for the late reply.
