Subject: Fix test case.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=876735a67f1fc4f1709985fde4511652d1e9e0df;p=clang

Fix test case.

r230921 broke backend-optimization-failure.cpp: after
r230921, LLVM no longer emits an expression to compute 'Length - 1'
and this perturbs LoopSimplify enough to emit the warning on line 10
instead of line 9.  This is a review request to fix the test case once
I re-land r230921.
