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/mips/mips.md (*udivmod<mode>4, udivmod<mode>4_mips16): Fix split condition. --- gcc/config/mips/mips.md | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
