Summary: This commit adds this alternate route only when parsing variable dies corresponding to global or static variables. The motivation for this is that GCC does not emit linkage names for functions and variables declared/defined in anonymous namespaces. Having this alternate route fixes one part of TestNamespace which fails when the test case is compiled with GCC. An alternate route to get fully qualified names of functions whose linkage names are missing will be added with a followup change. With that, the other failing part of TestNamespace will also be fixed. Test Plan: dotest.py -C gcc -p TestNamespace Reviewers: clayborg Reviewed By: clayborg Subscribers: lldb-commits Differential Revision: http://reviews.llvm.org/D8569 llvm-svn: 233098
