* dwarf_reader.cc (Sized_dwarf_line_info): Include all lines,
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.
