commit 874a73ea4 (HEAD -> master, upstream/master)
Author: Stan Cox <scox@redhat.com>
Date: Mon Nov 1 14:24:07 2021 -0400
Don't overflow aarch64 float register vector when setting used regs. (#1127)
Do not include the subtype when setting a float register as a used register if the registerSlot vector would be exceeded, e.g. for a value like 0x400 (Q_REG/register 0).

Load callee's address when the callee and caller are in the same module (#1056)
If the callee and caller are in the same module and pic is not
required then the callee's address can be loaded directly without
using a relocation.
