They're going to be hard to construct since they are sensitive to such
things as the number of registers saved.

When that option is enabled, STACK_BOUNDARY is set to 64.
But when you look at arm_expand_prologue, it appears that very little
effort is made to respect that alignment. Three specific cases I see
are the IS_NESTED case of pushing ip_rtx and, the lack of checking the
size of args_to_push, and no

I have also noticed that a series of

Phew, I just tried this:

I recently compiled the entire Debian archive (around 6500 packages
that need to be compiled) on SPARC using trunk to identify new issues
before GCC 4.3 is released. I compiled the archive twice, once with
default optimization levels specified by packages and once with
optimization set to -O3.
