/* 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. */
