Here's the basic design: - PropertyMapEntry tells you if a property is subject to type inference. If it is, then before storing into it, you need to look up the property's offset in the Structure's type inference table. If the value being stored is a member of the type according to that table, you can store. Otherwise, you need to do something to broaden the type. - The Structure's type inference table maps offsets to InferredType objects. InferredType objects are GC cells. - When a Structure transition occurs, the new structure's type inference table will share the same InferredType objects as the old structure for all of the properties that the two structures have in common. This ensures that if a store occurs on the old structure that causes a change in the inferred type, then users of the new structure immediately find out that they may now see that new type. Note that this is slightly conservative: it also means that if the type changes on the new structure, the old structure will find out, even though it doesn't need to. - All stores from a reflective context (i.e. not PutById) immediately disable type inference on the property by causing the InferredType to become TOP. - Dictionary transitions disable type inference by simply not copying the type inference table. This means that it doesn't affect the type inference of prior structures. It does mean that both the dictionary structure and all of its successors (including when it's flattened) will not enjoy type inference. The upside is that dictionary puts - which are expensive to begin with - don't have to validate types. We're assuming that once a dictionary transition happens then it's because many accesses will be reflective. Another common use of dictionaries is for prototypes, which will often be dictionaries until they are flattened. But prototype accesses usually benefit from immutable property inference already, so it's OK if type inference sometimes fails. - Property type will not, at least initially, have any effect on property representation. It just guarantees that you don't have to do some type check after load. - Property type will include Structure, for those Structures that have a valid transition watchpoint. InferredType will register a watchpoint on the transition, and will generalize to "Object" if the watchpoint fires. That way, we don't have to worry about some object having the structure at the time we store a reference into a property, but then the object's structure changes. We'll only do the inference if the transition had never fired, and when it does, the property finds out. - All put_by_id inline caches will have to do type checks, except of course when we already have a proof about what the type is. Such a proof will probably only happen in the DFG/FTL.

Created attachment 260294 [details] it's a start
Created attachment 260305 [details] some more stuff
Created attachment 260312 [details] wow, this is fun and easy! Still more code to write, but it's coming together nicely so far.
Created attachment 260323 [details] more things
Created attachment 260376 [details] more stuff Beefed up type check machinery in the DFG/FTL to deal with the ObjectWithStructureOrOther case. That was the only kind of type that the DFG/FTL couldn't previously check.
Created attachment 260936 [details] a little more
Created attachment 260955 [details] rebased and using a slightly more space-optimal InferredTypeTable
Created attachment 260958 [details] a bit more
Created attachment 261049 [details] more
Created attachment 261074 [details] just a bit more I've wired the put_by_id store checks into most things. I still need to wire it into the LLInt.
Created attachment 261136 [details] rebased
Created attachment 261159 [details] some more Slowly integrating into LLInt put_by_id inline caching.
Created attachment 261216 [details] LLInt put_by_id type checking is written OMG I'm so close now.
Created attachment 261223 [details] starting to compile
Created attachment 261240 [details] it compiles!
(In reply to comment #17) > Created attachment 261240 [details] > it compiles! r=me :D
Created attachment 261243 [details] it compiles! The last file I uploaded was an older patch.
Created attachment 261256 [details] it inferred a type! It just inferred that "f" is an Int32 below: function foo(o) { return o.f + 1; } noInline(foo); for (var i = 0; i < 10000; ++i) foo({f:i});
Created attachment 261275 [details] OMG it passed some tests
Created attachment 261284 [details] it passes many tests
Created attachment 261290 [details] more fixing Right now it looks like I might have introduced a performance pathology to inline caches because the no-access-inlining tests are timing out. Other than that, this is starting to look good.
Created attachment 261295 [details] even more fixing Fixed tag register usage in the put_by_id type check. That's what was causing bad performance.
This looks pretty good. Now I just need to fix the raytrace regression, and this will turn into a really nice speed-up. Benchmark report for Octane on shakezilla (MacBookPro11,3).

Also, the goal of property type inference is not to reinfer the original types used by every possible CrappyLanguage->JS compiler. For example, property type inference only infers that a property has some specific object type if that type doesn't have subtyping. And yes, we are already doing a pretty good job of running this benchmark.
Looks like the Raytrace regression is mostly a warm-up time regression. The benchmark runs a bit faster when you let it run long enough. I'll keep investigating.

If you have a property that points to either Foo or Bar then we will merge the two to "Object". I.e. it's not super useful for most programs.

Performance numbers of rebased/fixed patch: Benchmark report for SunSpider, LongSpider, V8Spider, Octane, Kraken, JSRegress, AsmBench, and CompressionBench on shakezilla (MacBookPro11,3). VMs tested: "TipOfTree" at /Volumes/Data/secondary/OpenSource/WebKitBuild/Release/jsc (r190059) "PropTypeInference" at /Volumes/Data/tertiary/OpenSource/WebKitBuild/Release/jsc (r190059) Collected 6 samples per benchmark/VM, with 6 VM invocations per benchmark. Emitted a call to gc() between sample measurements. Used 1 benchmark iteration per VM invocation for warm-up. Used the jsc-specific preciseTime() function to get microsecond-level timing. Reporting benchmark execution times with 95% confidence intervals in milliseconds.
