There are a few things i do not get. 1. The inliner heuristics depend on 2 parameters - the call_site_count and the invocation_count. The invocation_count is the number of times the method is executed in the previous tier. i.e. interpreter for tier 1 compilation and tier 1 for tier 2 compilation. But what does call_site_count represent. the number of callsites of this method within the all callers of the method ? It seems it is calculated based on MD0, what is the method data ? 2. Is it true that in theory all methods can be inlined in Java ? how about in the hotspot JVM ?
