Subject: [PATCH v2 02/40] bsd-user: Create setup_sigframe_arch to setup sigframe context
Date: Mon, 24 Jan 2022 18:29:09 -0700	[thread overview]
Message-ID: <20220125012947.14974-3-imp@bsdimp.com> (raw)
In-Reply-To: <20220125012947.14974-1-imp@bsdimp.com>

Define setup_sigframe_arch whose job it is to setup the mcontext for the
sigframe. Implement for x86 to just call mcontext.
