Full description

The destination of a goto statement is a nested code block. This check is identical to MISRAC++2008-6-6-1, MISRAC2012-Rule-15.3.

Coding standards
MISRA C:2012 Rule-15.3

(Required) Any label referenced by a goto statement shall be declared in the same block, or in any block enclosing the goto statement

MISRA C++ 2008 6-6-1

(Required) Any label referenced by a goto statement shall be declared in the same block, or in a block enclosing the goto statement.

Code examples

The following code example fails the check and will give a warning:

void f1 ( )
{
  int j = 0;
  goto L1;
  for (;;)
  {
L1: // Non-compliant
    j;
  }
}

The following code example passes the check and will not give a warning about this issue:

void f2()
{
  for(;;)
  {
    for(;;)
    {
      goto L1;
    }
  }
L1:
  return;
}
