Hi,
We're trying to figure out an optimally small yet performant set of gcc builds for shipping arm binaries of Julia (http://julialang.org)
Previously we've built two binaries with:
march=armv7-a
march=armv8-a
which has provided good broad support, but we had questions about whether performance can be improved, given speed improvements seen when building natively with `mcpu=native`.
The systems we're particularly interested in supporting are:
- Raspberry Pi 4 (cortex-a72)
- Nvidia jetson TX1, Nano (cortex-a57 / Denver2 v8)
- Nvidia Xavier NX (Nvidia carmel v8.2)
We generally advise building locally with `mcpu=native`, but can improvements be made for our binaries?
thanks
Ian
p.s. not sure if this is the right forum for this question
