How well is the Arm Cortex-R52 supported by Newlib?

[Alexander Fedotov (OSS)]

Hi Sebastian

I have pushed some changes in libgloss/arm/crt0.S to support initialization in Thumb mode. But I don't recall any more fixes and improvements for armv8-r.
I would say I'm interested in target optimizations 😊

Hello,

it seems nobody used Newlib for the Arm Cortex-R52 before

https://sourceware.org/pipermail/newlib/2020/018170.html

?

How well is the Arm Cortex-R52 supported by the machine-specific files in Newlib in general? For example, memcpy() just uses the C implementation. Are there some improved/updated routines available from Arm which haven't been committed to Newlib? I can prepare the patches, I just need some hints were I can find the latest stuff.
