Fix implicit pointer offsets. * dwarf2loc.c (indirect_pieced_value): Comment byte_offset. Use also ptr.OFFSET. gdb/testsuite/ Fix implicit pointer offsets. * gdb.dwarf2/implptr.c (add): New marker baz breakpoint. * gdb.dwarf2/implptr.exp (set baz breakpoint for implptr) (continue to breakpoint: continue to baz breakpoint for implptr) (sanity check element 0, sanity check element 1) (enter the inlined function, check element 0 for the offset) (check element 1 for the offset) (continue to breakpoint: ignore the second baz breakpoint): New tests. (set foo breakpoint for implptr): Update the breakpoint number.
