------- Comment #17 from jakub at gcc dot gnu dot org 2009-07-23 11:36 -------
Incorrect? Why do you think so?
double on ix86 has 8 byte alignment, and unlike long long it has also
performance effects when you misalign it (in theory, we could handle double the
same as long long with -Os though). When gcc needs to decide whether to align
the stack or not, it doesn't yet know whether any temporaries of that type will
need to be spilled to stack. -mpreferred-stack-boundary=2 is typically only
used in the kernel anyway and that one doesn't have floating point stuff, as
this option affects the Linux ABI (you can't call libc functions from code
compiled that way among other things).
