Yes, it is very worth doing it:

make <path-to-file>.s

is one of the basic steps one does when trying to pinpoint the Code:
line in a splat back to the code gcc generated.

Yes, you can do it this way too but I can't apply it here to play with
it because gmail probably corrupted the diff:

checking file Makefile
Hunk #1 FAILED at 729.
1 out of 1 hunk FAILED
checking file scripts/Makefile.build
patch: **** malformed patch at line 98: $(DISABLE_LTO) -fverbose-asm -S -o $@ $<

Please attach the diff or send it from another mail server.

Thx.
