  16 /* This test demonstrates a failure to resolve opaque structure types in
  17    binaries compiled by the Intel C compiler.  This is GDB PR symtab/13277.
  18
  19    The test was derived from opaque-pointer.c, which contains the single line:
  20
  21    struct opaque_struct_t *p_struct;
  22
  23    and opaque_struct.c, which looks like:
  24
  25    struct opaque_struct_t
  26    {
  27      int wrapped_value;
  28    };
  29
  30    struct opaque_struct_t opaque_internal = { 0 };
  31
  32    What follows is a simplified version of the debug info generated by ICC
  33    version 12.0.4.191. */
