Subject: [PATCH v2 20/26] target/arm/tcg: Move v8m_stackcheck() from op_helper.c to m_helper.c
Date: Sun, 11 Jun 2023 10:58:40 +0200	[thread overview]
Message-ID: <20230611085846.21415-21-philmd@linaro.org> (raw)
In-Reply-To: <20230611085846.21415-1-philmd@linaro.org>

No need to have the v8m_stackcheck() helper in the generic
op_helper.c, move it with the rest of the M-profile helpers.
