* DIEHashing: Provide an assert for unreachable functionality regarding friends.David Blaikie2013-10-221-0/+3
| | | | | | | | | | | | | Since (as of r190716) Clang no longer emits debug info for C++ friend declarations (and it seems GCC never has/does, which was the motivation for the Clang change), there's no actual reachable case for implementing the part of DWARF 4, Section 7.27 part 5 that pertains to friends. Leave an assert here so that if/when we do have a client producing friends and using type units, we can fill in the gap and add appropriate (unit and feature) tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193193 91177308-0d34-0410-b5e6-96231b3b80d8
* DWARF type hashing: pointers to membersDavid Blaikie2013-10-221-11/+14
| | | | | | | | | Includes a test case/FIXME demonstrating a bug/limitation in pointer to member hashing. To be honest I'm not sure why we don't just always use summary hashing for referenced types... but perhaps I'm missing something. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193175 91177308-0d34-0410-b5e6-96231b3b80d8

* DebugInfo: Hash DW_FORM_GNU_str_index as a string.David Blaikie2013-10-211-1/+3
| | | | | | | | | | Found while adding type safety to the various DWARF enumerations (form, attribute, tag, etc) that caused Clang to warn on an incompletely covered switch. Converting the comment to a default/unreachable uncovered this case of an unsupported form encoding. Seems we were skipping fission strings entirely. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193089 91177308-0d34-0410-b5e6-96231b3b80d8
