Subject: [PULL 06/15] bsd-user:Add setup_sigframe_arch function for ARM AArch64
Date: Wed, 24 Jul 2024 16:04:39 -0600	[thread overview]
Message-ID: <20240724220449.10398-7-imp@bsdimp.com> (raw)
In-Reply-To: <20240724220449.10398-1-imp@bsdimp.com>

The function utilizes the `get_mcontext` function to retrieve the machine
context for the current CPUARMState
