Subject: [testsuite] New effective target long_neq_int
Date: Thu, 09 Aug 2012 15:46:36 -0000

As suggested by Janis regarding testsuite/gcc.dg/tree-ssa/slsr-30.c,
this patch adds a new effective target for machines having long and int
of differing sizes.

Tested on powerpc64-unknown-linux-gnu, where the test passes for -m64
and is skipped for -m32.  Ok for trunk?

Thanks,
Bill
