<pre>After applying <a href="https://reviews.llvm.org/D91734">https://reviews.llvm.org/D91734</a> the test
llvm/test/CodeGen/Mips/emergency-spill-slot-near-fp.ll
began failing. The test uses a long sequence of volatile loads and stores
to try to create enough register pressure to trigger the use of the
"emergency spill slot" which appears to be at 0(fp). With the above patch,
register usage changed enough that this spill slot wasn't required.
I tried adding more loads and stores, but that just caused a normal spill
and reload. Rather than have this one test block the patch, @rnk proposed
that I mark it XFAIL and file this bug.
I'll commit D91734 shortly, and post the git hash here.</pre>
