      "message": "ART: Print C1vis lists as [v1,...,vN]\n\nChecker interprets whitespace as a don\u0027t-care placeholder, making it\neasier to write assertions which test only parts of the output (e.g.\n\"//CHECK: Add liveness:44\" does not test the inputs or any other\nattributes apart from \"liveness\").\n\nHowever, since the GraphVisualizer prints lists with elements\nseparated by spaces (\"[ v1 ... vN ]\"), this allows for false positives\ncaused by an occurrence elsewhere in the output. For example, the\nassertion: \"//CHECK: [ x y ]\" will match \"[ x y ]\" but also\n\"[ x a y b ]\" or even \"[ x ] abc [ y ]\".\n\nSwitching to comma-separated lists works around this issue.\n\nThis patch updates all test files, fixes one false positive that this\nchange revealed (test 442, line 337) and two occurrences of a wrong\nmatch (test 462, lines 121, 149).\n\nBug: 21189305\nChange-Id: I3b22503be3d92529dac0b13f66bccbcfabea6721\n"

It is primarily\nintended for writing tests for the optimizing compiler but could be\nconfigured for other use cases too. It is implemented from scratch in\norder to avoid dependency on LLVM.\n\nChecker tests are written in Java and dex2oat is invoked with a flag\nwhich dumps the CFG before and after each pass of the optimizing\ncompiler. The output is then compared against assertions in the\ntest\u0027s comments parsed by Checker. See comments in tools/checker.py\nfor more details about the currently supported language features.\n\nThis initial CL implements only one type of assertion - whether the\noutput contains lines matching a desired pattern in the given order -\nbut supports both plain text and regex matching and allows for\nequivalency testing by matching for the outcome of a previous match.\nSee the tests in compiler/optimizing/test/ConstantFolding.java for\nexamples.\n\nChange-Id: I1ad7431b399c38dc0391ccee74d2c643ba0b0675\n"
