Subject: [PATCH v3 08/29] bsd-user/arm/target_arch_cpu.h: Implement data abort exceptions
Date: Thu, 4 Nov 2021 08:05:15 -0600 [thread overview]
Message-ID: <20211104140536.42573-9-imp@bsdimp.com> (raw)
In-Reply-To: <20211104140536.42573-1-imp@bsdimp.com>
Implement EXCP_PREFETCH_ABORT AND EXCP_DATA_ABORT. Both of these data
exceptions cause a SIGSEGV.
