--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The reason for the limitation is that any needed reload out can't be then
inserted after the asm goto, but all the other edges would need to be split and
the reload outs inserted on all the edges.
Looking at your example though, can you explain why you want to use asm goto
then? I'd say that for addition, two conditional jumps and one comparison you
definitely don't want to use asm goto, the compiler can't see through it thus
can't optimize it. Why isn't what GCC generates sufficient? Do you have a
testcase?
