            Bug ID: 49266
           Summary: clang (inline-asm): assertio 'castIsValid(op, S, Ty)
                    && "Invalid cast!"' failed
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: -New Bugs

It seems a less-interesting ICE, caused by inline-asm. The test-case escapes
from the frontend checking.

I just report here for any future improvement.

int main() { asm("" : "=a"(a), "=d"(b) : "1"(__builtin_nanf(0))); }
