[fpc-devel] Any word on this ARM / AArch64 optimisation?

[J. Gareth Moreton]

That's fair.  We probably need to start building more tests for the test 
suite at some point to catch the causes of these bugs, like you hinted 
with some of the bugs introduced with my peephole optimizations! (Sorry 
about that!)

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).
