/* This test demonstrates a failure to resolve opaque structure types in
binaries compiled by the Intel C compiler. This is GDB PR symtab/13277.
The test was derived from opaque-pointer.c, which contains the single line:
struct opaque_struct_t *p_struct;
and opaque_struct.c, which looks like:
struct opaque_struct_t
{
int wrapped_value;
};
struct opaque_struct_t opaque_internal = { 0 };
What follows is a simplified version of the debug info generated by ICC
version 12.0.4.191. */
