but mark earlier ones as non-canonical (offset_to_iterator): Update search target and example (do_addr2line): Return extra lines in a vector* (format_file_lineno): Extract from do_addr2line (one_addr2line): Add vector* out-param * dwarf_reader.h (Offset_to_lineno_entry): New field recording when a lineno entry appeared last for its instruction (Dwarf_line_info): Add vector* out-param * object.cc (Relocate_info): Pass NULL for the vector* out-param * symtab.cc (Odr_violation_compare): Include the lineno in the comparison again. (linenos_from_loc): New. Combine the canonical line for an address with its other lines. (True_if_intersect): New. Helper functor to make std::set_intersection a query. (detect_odr_violations): Compare sets of lines instead of just one line for each function. This became less deterministic, but has fewer false positives. * symtab.h: Declarations. * testsuite/Makefile.am (odr_violation2.o): Compile with -O2 to mix an optimized and non-optimized object in the same binary (odr_violation2.so): Same. * testsuite/Makefile.in: Regenerate from Makefile.am. * testsuite/debug_msg.cc (main): Make OdrDerived classes. * testsuite/debug_msg.sh: Update line numbers and add assertions. * testsuite/odr_violation1.cc: Use OdrDerived, in a non-optimized context. * testsuite/odr_violation2.cc: Make sure Ordering::operator() isn't inlined, and use OdrDerived in an optimized context. * testsuite/odr_header1.h: Defines OdrDerived, where optimization will change the first-instruction-in-the-destructor's file and line number. * testsuite/odr_header2.h: Defines OdrBase.
