2014-12-23 Cary Coutant <ccoutant@google.com>
include/
* dwarf2.def (DW_FORM_line_strp): New constant.
* dwarf2.h (enum dwarf_line_number_ops): Add DW_LNS_inlined_call,
DW_LNS_pop_context, DW_LNS_set_context,
DW_LNS_set_address_from_logical.
(enum dwarf_line_number_content_type): Add new DW_LNCT_ codes.
