/* PR17544 Incorrect -Wunreachable-code warning Origin: sebor@roguewave.com G++ appends 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 "-O -Wunreachable-code" } */ int main (int argc, char *argv[]) { const char* const s = argc < 2 ? "" : argv [1]; int i = 0; do { ++i; } while (i < s [0]); return i; }
