Subject: [PATCH] sh: use __builtin_constant_p() directly instead of IS_IMMEDIATE()
Date: Tue, 23 Jul 2019 16:49:43 +0900 [thread overview]
Message-ID: <20190723074943.17093-1-yamada.masahiro@socionext.com> (raw)
__builtin_constant_p(nr) is used everywhere now. It does not make
much sense to define IS_IMMEDIATE() as its alias.
