Subject: [PATCH 01/22] target/arm: Remove local definitions of float constants
Date: Mon, 24 Aug 2020 15:29:13 +0100 [thread overview]
Message-ID: <20200824142934.20850-2-peter.maydell@linaro.org> (raw)
In-Reply-To: <20200824142934.20850-1-peter.maydell@linaro.org>
In several places the target/arm code defines local float constants
for 2, 3 and 1.5, which are also provided by include/fpu/softfloat.h.
Remove the unnecessary local duplicate versions.
