That will likely hurt performance quite a bit (I don't have figures, but
I guess 10-20%). Often the cause is some inlining or other
optimisations that put extra strain on gcc's register allocator, so it
is usually best to try to track down and avoid these. Or use the native
code generator, if that's possible for the source file in question.
Cheers,
Simon
