Given we have code like: void test_lround (long *out, double *in, unsigned count) { for (unsigned i = 0; i < count; i++) out[i] = __builtin_lround (in[i]); } Before this patch: .L3: ... fld fa5,0(a1) fcvt.l.d a5,fa5,rmm sd a5,-8(a0) ... bne a1,a4,.L3 After this patch: frrm a6 ... fsrmi 4 // RMM .L3: ... vsetvli a3,zero,e64,m1,ta,ma vfcvt.x.f.v v1,v1 vsetvli zero,a2,e64,m1,ta,ma vse32.v v1,0(a0) ... bne a2,zero,.L3 ... fsrm a6 The rest part like SF => DI/HF => DI/DF => SI/HF => SI will be covered by TARGET_VECTORIZE_BUILTIN_VECTORIZED_FUNCTION. gcc/ChangeLog: * config/riscv/autovec.md (lround2): New pattern for lround/lroundf. * config/riscv/riscv-protos.h (enum insn_type): New enum value.
