llvm/test/CodeGen/PowerPC/ppc64-toc.ll
Bill Schmidt 527388dea5 This patch is in preparation for adding medium code model support to the
PPC64 target.  The five tests modified herein test code generation that is
sensitive to the code model selected.  So I've added -code-model=small to
the RUN commands for each.

Since small code model is the default, this has no effect for now; but this
prepares us for eventually changing the default to medium code model for PPC64.

Test changes verified with small and medium code model as default on
powerpc64-unknown-linux-gnu.  All tests continue to pass.
