It's quite good at increasing speed and shrinking code size by concatenating writes to the stack, among other things: https://gitlab.com/freepascal.org/fpc/source/-/merge_requests/104 - the new CPU feature flag I put in will also mean I can use it on ArmV7A to improve constant generation (for ARM, it requires at least an ARMV7A architecture, and for AArch64 it always works).

I am currently a little bit more careful with merging as we had some subtile bugs recently and I want to wait till things settle down first.
