> The existing llvm\test\CodeGen\X86\vec_fpext.ll and llvm\test\CodeGen\X86\vec_int_to_fp.ll already demonstrate the correct optimized DAG codegen using the same IR as output in the clang\test\CodeGen\*-builtins.c here.


That's what I meant by "Do you know if there are already CG tests that check we correctly lower these IR patterns", sorry I wasn't more clear.
This LGTM.
