This patch implements a test that ensures that with "set print object on", -var-create returns "<optimized out>" for an optimized out pointer to structure, rather than throwing an error, while also ensuring that any attempt to dereference the pointer *will* throw an error. It uses the dwarf assembler to construct the appropriate debug info to represent a pointer-to-struct in the program as optimized out, and then accesses that pointer in various ways. The test uses both the console interpreter and the MI interpreter. gdb/testsuite/ChangeLog: 2016-04-06 Don Breazeal <donb@codesourcery.com> * gdb.dwarf2/dw2-opt-structptr.c: New test program. * gdb.dwarf2/dw2-opt-structptr.exp: New test script.
