As far as we're aware, it's impossible to restore the *whole* context simultaneously, without using privileged instructions like ERET. You need to scratch a register to set the instruction pointer. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 51996] New: aarch64: NtGetContextThread/NtSetContextThread on another thread ignores FPU state due to buggy SIGUSR1 handler

by WineHQ Bugzilla

The bug can be traced back to commit 07f37f21377 (ntdll: Add support for saving/restoring FPU state on ARM64., 2019-08-13), which implements save_fpu()/restore_fpu() but does not make use of them in save_context()/restore_context(). -- Do not reply to this email, post in Bugzilla using the above URL to reply.
