      "message": "Introduce Signature type to avoid string comparisons.\n\nMethod resolution currently creates strings to then compare with strings formed\nfrom methods in other dex files. The temporary strings are purely created for\nthe sake of comparisons. This change creates a new Signature type that\nrepresents a method signature but not as a string. This type supports\ncomparisons and so can be used when searching for methods in resolution.\n\nWith this change malloc is no longer the hottest method during dex2oat (now its\nmemset) and allocations during verification have been reduced. The verifier is\ncommonly what is populating the dex cache for methods and fields not declared\nin the dex file itself.\n\nChange-Id: I5ef0542823fbcae868aaa4a2457e8da7df0e9dae\n"
