That's interesting. Personally, I used this option many times in the past
in order to investigate a few unexpected performance regressions. I had
always assumed that, apart from the additional source coded intermixed,
the assembler was accurately preserved (vs that produced by gcc -S)....

Could you possibly provide some pointers to the "skips" you mention?
(perhaps we are a little bit off-topic, should we move the discussion to
the binutils lists?)

Cheers,
