The full diff for the test directory may be hard to read because of the filename clash; so here's all that happened as far as the tests are concerned: ``` cd test/Transforms/RewriteStatepointsForGC git rm *ll git mv deopt-bundles/* ./ rmdir deopt-bundles find . -name '*.ll' | xargs gsed -i 's/-rs4gc-use-deopt-bundles //g' ``` llvm-svn: 259129
