      "message": "Ensure ClearLoopInformation doesn\u0027t require particular ordering\n\nThe ClearLoopInformation call used to use the RPO list to find\nblocks which potentially had loop-information. This meant that if one\nwas also clearing the dominance information (which is quite common)\none needed to be sure to call ClearLoopInformation before calling\nClearDominanceInformation or else loop information will not be fully\ncleared. This could cause quite perplexing errors if dominance\ninformation is recomputed later (also quite common). This error is in\nfact present in several tests (none of which use loops which is how it\ngot missed).\n\nFix this issue by just looping over all blocks. Also add a new\nGetActiveBlocks function which does the filtering of null blocks\nautomatically. In many cases (such as these) we use RPO purely because\nit doesn\u0027t require filtering. This should be able to replace these\nuses.\n\nTest: ./test.py --host\nChange-Id: I60c7defc409111471064e9bf02b7ae3a0eb10584\n"
