Subject: [PATCH v16 51/99] target/arm: move exception code out of tcg/helper.c
Date: Fri,  4 Jun 2021 16:52:24 +0100	[thread overview]
Message-ID: <20210604155312.15902-52-alex.bennee@linaro.org> (raw)
In-Reply-To: <20210604155312.15902-1-alex.bennee@linaro.org>

From: Claudio Fontana <cfontana@suse.de>

cpu-sysemu.c:

we need this sysemu code for KVM too, so we move the code to
cpu-sysemu.c so we can reach a builable state.

There will be further split later on in dedicated
exception modules for 32 and 64bit, after we make more
necessary changes to be able to split TARGET_AARCH64-only code.

tcg/sysemu/tcg-cpu.c:

the TCG-specific code we put in tcg/sysemu/, in preparation
for the addition of the tcg-cpu accel-cpu ARM subclass.
