🐛 fix stack alignment upon first procedure entry #1021

stnolting · 2024-09-15T19:38:33Z

The stack grows downwards (towards lower addresses) and the stack pointer shall be aligned to a 128-bit boundary upon procedure entry.

This PR fixes the initial alignment of the stack (make it 128-bit-aligned) in crt0 before entering the very first procedure, which is main.

This is quite experimental and needs further testing.

Fixing #1020.
