Then let's fix it, as you said there "We fail to pass -fno-exceptions -fno-rtti

This is a tweak for signed 16- and 32-bit division routines.
The old code called subroutine __divmod{si|hi}4_neg1 and returned if T-flag is
not set. This is costly. By shuffling the instructions the test can be moved
up without increasing the code size but saving calls here and there.

Richard,
I plan to commit this patch to simplify the generation of linkage entries.
Instead of a splay_tree, it adds a field in machine_function.
But because the new field is controlled by GGC, it is present on (and thus
affect) all alpha targets (it cannot be enclosed by #if/#endif).
