            Bug ID: 70859
           Summary: Bad column number in type-generic function errors
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jsm28 at gcc dot gnu.org
  Target Milestone: ---

The errors for calling type-generic floating-point built-in functions with bad
argument types point to the start of the line, not to the argument in question:

int f (void) { return __builtin_isfinite (0); }
int g (void) { return __builtin_isless (0, 0); }

t.c: In function 'f':
t.c:1:1: error: non-floating-point argument in call to function
'__builtin_isfinite'
 int f (void) { return __builtin_isfinite (0); }
 ^~~
t.c: In function 'g':
t.c:2:1: error: non-floating-point arguments in call to function
'__builtin_isless'
 int g (void) { return __builtin_isless (0, 0); }
 ^~~

For C++, they point to the closing parenthesis, which is closer, but still
wrong.

t.c: In function 'int f()':
t.c:1:44: error: non-floating-point argument in call to function
'__builtin_isfinite'
 int f (void) { return __builtin_isfinite (0); }
                                            ^
t.c: In function 'int g()':
t.c:2:45: error: non-floating-point arguments in call to function
'__builtin_isless'
 int g (void) { return __builtin_isless (0, 0); }
                                             ^
