+ case X86::BI__builtin_ia32_sqrtpd512_mask_nr:
+ case X86::BI__builtin_ia32_sqrtps512_mask_nr: {
+ Function *F = CGM.getIntrinsic(Intrinsic::sqrt, Ops[0]->getType());
----------------
I would suggest just using __builtin_i32_sqrtpd512_mask here and select
different intrinsics based on the value of the rounding mode operand. The user
should get the same behavior if they use the explicit rounding mode intrinsic,
but pass CUR_DIRECTION.
