I tried using __builtin_nanf("0xFFFFFFFF"), but got 0x7FFFFFFF instead
why is the sign bit never set?
Is this the intended behaviour?
https://github.com/llvm/llvm-project/blob/main/clang/lib/AST/ByteCode/InterpBuiltin.cpp#L363
I know the the sign bit is not really relevant for NAN, but if we provide the exact bits, __builtin, should not ignore the sign value
