For example as below, and we arrange the iterator similar to fcvt. * SF => SI * DF => DI After we refined this limination from middle-end, these API can also vectorized with different type sizes, aka: * HF => SI, HF => DI * SF => DI, SF => SI * DF => SI, DF => DI Then the iterator cannot take care of this simply and this patch would like to re-arrange the iterator in two items. * V_VLS_F_CONVERT_SI: handle (HF, SF, DF) => SI * V_VLS_F_CONVERT_DI: handle (HF, SF, DF) => DI As well as related mode_attr to reconcile the new iterator. gcc/ChangeLog: * config/riscv/autovec.md (lrint2): Remove. (lround2): Ditto. (lceil2): Ditto. (lfloor2): Ditto. (lrint2): New pattern for cvt from FP to SI. (lround2): Ditto. (lceil2): Ditto. (lfloor2): Ditto. (lrint2): New pattern for cvt from FP to DI. (lround2): Ditto. (lceil2): Ditto. (lfloor2): Ditto. * config/riscv/vector-iterators.md: Renew iterators for both the SI and DI.
