Yes, of course. You have a literal float multiplied by a literal int.
The compiler should promote the int and multiply. After that, the compiler
should convert the result to an int, eliminating the cast. Then the compiler
should store that int value in the object file. Why not?
If this has anything to do with IEEE rounding modes, gross!
In that case, gcc needs a -flinux-kernel option. Maybe one of the
existing flags will make gcc optimize away the floating point math.
How about -ffast-math?
