--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Note, in qemu it isn't just those newlines but simply a long inline asm.
It can very well be something that is empty or very short in the .text sect=
ion,
e.g. can .pushsection; .section whatever; put lots of stuff in there;
.popsection.
But as inline asm is a black box to gcc, we have only very rough estimation=
 for
the inline asm text length, which just counts how many newlines and typical=
ly ;
characters there are and multiple that by some insn size.=
