/* PR17544 Incorrect -Wunreachable-code warning
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. */
/* { dg-do compile } */
/* { dg-options "-std=c99 -O -Wunreachable-code" } */
int main (void) // 1
{ // 2
return 0; // 3
} // 4
