Nope. But objdump can, e.g.

powerpc-eabi-objdump -drS redboot.elf

but the output can be awkward to read.

Obviously your source files must be the same as when you built the
executable to get sensible output. It will print out /mywork/foo.c line
145 whatever that file or line actually is, irrespective of whether it's
changed since the executable was built!
