Subject: [PATCH for 6.2 40/49] bsd-user: Add target_arch_reg to describe a target's register set
Date: Sat, 7 Aug 2021 15:42:33 -0600 [thread overview]
Message-ID: <20210807214242.82385-41-imp@bsdimp.com> (raw)
In-Reply-To: <20210807214242.82385-1-imp@bsdimp.com>
From: Warner Losh <imp@FreeBSD.org>
target_reg_t is the normal register. target_fpreg_t is the floating
point registers. target_copy_regs copies the registers out of CPU
context for things like core dumps.
