Subject: [PATCH 05/15] v850: Fix non-robust split condition in define_insn_and_split
Date: Thu, 11 Nov 2021 05:24:49 -0600 [thread overview]
Message-ID: <c036f8bac2b15e1dbfc4d568436af04db4de8093.1636621345.git.linkw@linux.ibm.com> (raw)
In-Reply-To: <cover.1636621345.git.linkw@linux.ibm.com>
This patch is to fix some non-robust split conditions in some
define_insn_and_splits, to make each of them applied on top of
the corresponding condition for define_insn part, otherwise the
splitting could perform unexpectedly.
gcc/ChangeLog:
* config/v850/v850.md (cbranchsf4, cbranchdf4, *movsicc_normal,
*movsicc_reversed): Fix split condition.
