Hi, Andrew,
My question is that GCC treats the identifier "__builtin_unreachable" and
normal identifier differently?
For example
$cat test.cc
int foo_long_identifier(){;}
int main(){
foo_long_identifier();
}
$g++ -w -fsanitize=undefined test.cc ; ./a.out
test.cc:1:5: runtime error: execution reached the end of a value-returning
function without returning a value
I think this time the column number is the start of the identifier
"foo_long_identifier" rather than "()".
