Subject: [PATCH 28/28] cputlb: Expand cpu_ldst_template.h in cputlb.c
Date: Wed, 11 Dec 2019 20:00:39 -0800 [thread overview]
Message-ID: <20191212040039.26546-29-richard.henderson@linaro.org> (raw)
In-Reply-To: <20191212040039.26546-1-richard.henderson@linaro.org>
Reduce the amount of preprocessor obfuscation by expanding
the text of each of the functions generated. The result is
only slightly smaller than the original.
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
