-let Predicates = [HasStdExtF, IsRV32] in {
-// FP->[u]int. Round-to-zero must be used
-def : Pat<(fp_to_sint FPR32:$rs1), (FCVT_W_S $rs1, 0b001)>;
-def : Pat<(fp_to_uint FPR32:$rs1), (FCVT_WU_S $rs1, 0b001)>;
 
-// [u]int->fp. Match GCC and default to using dynamic rounding mode.
-def : Pat<(sint_to_fp GPR:$rs1), (FCVT_S_W $rs1, 0b111)>;

Looks like a likely holdover of some rebasing. I agree, these patterns can be deleted. Please do land that NFC change directly.
