      "message": "Better support ICs on virtual calls\n\nDue to the way we implement profiles InlineCaches are only valid on\nmethods with implementations. Unfortunately due to the rather slow way\nwe update boot profile definitions code refactorings can lead to\ninline-caches being lost. This change makes profman more resilient to\nthis error by searching up the superclass resolutions to try to find a\nmethod the inline-caches can be attached to.

      "message": "Add text-profile support for multiple ICs\n\nText profile inline-cache support was limited to methods with only a\nsingle invoke. This extends support so it is instead based on the\nreceiver type and supports an arbitrary number of invokes. It does\nassume that all invokes of the same receivers should have the same\nICs. This enables us to create text profiles that can survive most\ncommon edits to the underlying java language files.\n\nIC lines are of the following format\n\n\u003c\u003cCLASS_GROUP\u003e\u003e :\u003d {CLASS}(,{CLASS})*\n\u003c\u003cIC_GROUP\u003e\u003e :\u003d \\[{CLASS}{CLASS_GROUP}\n\u003c\u003cIC_LINE\u003e\u003e :\u003d {PROFILE_FLAGS}{CLASS}-\u003e{METHOD}\\+{IC_GROUP}*\n\nThis means a typical line might look like:\n\n```\nHLTestInline;-\u003einlineTriplePolymorphic(LSuper;LSecret;LSecret;)I+[LSuper;LSubA;,LSubB;,LSubC;[LSecret;LSubB;,LSubC;\n```\n\nNote that old style single-invoke IC lines are still supported as\nwell and their format has not changed.\n\nUpdated --dump-classes-and-methods to dump ICs using this format. Note\nthat it will combine ICs for different pcs with the same target so it\nis possible to construct a profile where the \u0027profile -\u003e dump -\u003e\nprofile\u0027 operation is not idempotent. Any profile coming from a\ntext-dump will be idempotent under this transform.\n\nTest: ./test.py --host\nBug: 168941430\nChange-Id: I69ba3b312caa7ca454487aaeb49862e393de3a4a\n"
