Sorry - objdump has no such option.

The problem is that the same line of source code can appear in lots of places
in the assembler (for example because of macros, inline functions, templates, etc).
Plus compiler optimizations like loop unrolling can replicate the same line
of source code multiple times in the assembler output. So there really is no
easy way to produce *meaningful* disassembly sorted by line number.

You can of course write a script to perform this sorting for you, so that you
do not have to do it by hand every time.
