Yes, and just like Intel & AMD spent a lot of effort/funding for building performance libraries and compilers, we should expect Amazon and Apple invest into similar efforts.

Apple will definitely give all the necessary tools as part of Xcode for iOS/MacOS software optimisation.

AWS is going to be more interesting – this is a great opportunity for them to provide distributed profiling/tracing tools (as a hosted service, obviously) for Linux that run across a fleet of Graviton instances and help you do fleet-wide profile guided optimizations.

We should also see a lot of private companies building high-performance services on AWS to contribute to highly optimized open-source libraries being ported to graviton.

So far I found getting started repo for Graviton with few pointers https://github.com/aws/aws-graviton-getting-started

What kind of pointers were you expecting?

I found it to have quite a lot of useful pointers. Specifically –https://static.docs.arm.com/swog309707/a/Arm_Neoverse_N1_Sof...

https://static.docs.arm.com/ddi0487/ea/DDI0487E_a_armv8_arm....

- these two docs gives lot of useful information.

And the repo itself contain a number of examples (like ffmpeg) that have been optimized based on these manuals.
