memory usage optimization, because this code is just bogus and causes
access-beyond-allocated-size SIGSEGV in the wild.
This is part of a larger diff (being worked on) backporting the removal of
``permanent_obstack'' completely from gcc, as done by the gcc folks in 3.x
after they came to their senses (or got tired of dissecting coredumps on
platforms with strong malloc implementations).
Only affects m68k, m88k and vax; collecting dust in the m88k tree, commit
triggered by sebastia@ via espie@ as this fixes the devel/gperf port on vax.

construct, so that it is still written in rtl statements, and part of
it can be put in a delay slot. And the way it's written now, it does not
create bogus uninitialized warnings.

the two SImode subregs of the DImode destination operand, this confuses
the register life analysis and causes gcc to emit wrong warning about
values not being initialized.
Unfortunately, the fallback logic infers a worse sequence (mov + cmp against
zero + ext of the cmp signedness bit, instead of mov + ext of the sign bit),
which wastes an instruction and a register.
This is hopefully a temporary measure until a nonconfusing flavour of the
fast expansion is devised (preferrably one which does not expose the
optimize_reg_copy_3 big-endian bug as well).

functions which are too greedy in stack variables.
This is intended to be used for kernel compiles, where this warning will
be enabled for a reasonable size (after a few weeks grace period so that
people can upgrade their compiler).
Please note that this warning relies upon md code, and as such is only
available on platforms OpenBSD runs on; also, the stack size being warned
on is only the local variables size, regardless of the ABI stack usage
requirements and the callee-saved registers; which means a function may
be warning-clean yet need more stack space than meets the eye; the
actual size being checked on may change to include these extras in the
future.
