Implement code sinking. Small example of what the optimization does: Object o = new Object(); if (test) { throw new Error(o.toString()); } will be turned into (note that the first user of 'o' is the 'new Error' allocation which has 'o' in its environment): if (test) { Object o = new Obect(); throw new Error(o.toString()); } There are other examples in 639-checker-code-sinking. Ritz individual benchmarks improve on art-jit-cc from 5% (EvaluateComplexFormulas) to 23% (MoveFunctionColumn) on all platforms. Test: 639-checker-code-sinking Test: test-art-host Test: borg job run Test: libcore + jdwp bug:35634932 bug:30933338 Change-Id: Ib99c00c93fe76ffffb17afffb5a0e30a14310652
