| Origin: Giovanni Bajo | |
| In C99 we append a "return 0;" when finishing a function, but it was | |
| not given a source location. The gimplifier thinks a return statement | |
| needs a locus so it would add one, making the compiler generated code | |
| visible to the unreachable code warning. */ | |
