PR70674: S/390: Add memory barrier to stack pointer restore from fpr.
This patches fixes a problem with stack variable accesses being
scheduled after the stack pointer restore instructions. In the
testcase this happened with the stack variable 'a' accessed through the
frame pointer.
The existing stack_tie we have in the backend is basically useless
when trying to block stack variable accesses from being scheduled
across an insn. The alias set of stack variables and the frame alias
set usually differ and hence aren't in conflict with each other. The
solution appears to be a magic MEM term with a scratch register which
is handled as a full memory barrier when analyzing scheduling
dependencies.
With the patch a (clobber (mem:BLK (scratch))) is being added to the
restore instruction in order to prevent any memory operations to be
scheduled across the insn. The patch does that only for the one case
where the stack pointer is restored from an FPR. Theoretically this
might happen also in the case where the stack pointer gets restored
using a load multiple. However, triggering that problem with
load-multiple appears to be much harder since the load-multiple will
restore the frame pointer as well. So in order to see the problem a
different call-clobbered register would need to be used as temporary
stack pointer.
Another case which needs to be handled some day is the stack pointer
allocation part. It needs to be a memory barrier as well.
Bootstrapped and regression tested with --with-arch z196 and z13 on
s390 and s390x.
