Agus Zubiaga	27aab8b69a	Use X15 instead of requesting general reg	2023-10-09 15:24:34 +02:00
Agus Zubiaga	1021423e69	Use reg from StorageManager instead of XR while loading args ... When a function returns via arg pointer, the caller sets XR (x8) to the address where the return value goes. We were sometimes using XR as a temporary register while loading args, which lead to a segfault when returning. It will now request a general available register from StorageManager instead.	2023-10-09 15:24:33 +02:00
