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. */
