[Bug tree-optimization/20767] New: gcc.dg/tree-ssa/ssa-pre-8.c scan-tree-dump-times Eliminated: 4 1 fails on 64-bit systems

[jsm28 at gcc dot gnu dot org]

FAIL: gcc.dg/tree-ssa/ssa-pre-8.c scan-tree-dump-times Eliminated: 4 1

appears on hppa64-hpux and on ia64-hpux with -mlp64.  gcc-testresults
also shows it on powerpc64-linux-gnu, x86_64-linux-gnu and mips-irix with
-mabi=64, so this appears to be a generic 64-bit problem.

Can you send me the dump file?
I suspect it's eliminating 3 instead of 4 or something (and it's
probably none of the eliminations we care about)

Or it might be elimitating 5 since there is an extra cast.

The problem is that we eliminate 5 instead of 4.
Eliminated: 5

The easy fix to make sure that this does not fail on any target is the following:
