Comment 26 2016-07-29 17:52:16 PDT

Looks like Octane/deltablue crashes with this patch. Internal tests didn't catch it probably because you have to run long enough to cause the bad GC thing to happen. Also, this looks like a 1% SunSpider regression. I'll investigate the deltablue crash first.

Filip Pizlo

Comment 27 2016-07-29 19:26:18 PDT

It appears that deltablue requires an FTL fast path allocation for the bug to happen. It looks as though the GC swept over a butterfly that some object was still referring to. At the time the GC tries to visit the butterfly, it's clear that the start of the butterfly has a freelist next pointer and the rest of it has been overwritten by my new poisoning pass, where sweeping overwrites the things it sweeps with dummy values. Disabling either the FTL or forcing slow path allocations fixes it. Also, the poisoning is catching tons of bugs in normal tests. We probably want to run tests in a mode that does this poisoning. So, I've got a lot of problems to work through: - 1% SunSpider regression - deltablue crash due to FTL fast path allocation bug - crashes when poison-sweeping is enabled, indicating a failure to clear butterflies in some places

Filip Pizlo

Comment 28 2016-07-29 19:34:36 PDT

It looks like disabling generational GC also causes deltablue to run correctly. So, this may be a missing barrier!

Filip Pizlo

Comment 29 2016-07-29 23:01:41 PDT

Oh man. It looks like we're GCing in operationNewArrayWithSize, after allocating the butterfly but before allocating the object. That GC works fine, but the *next* GC goes mad while trying to scan that object. Between the two GCs, we sweep the block, and we find the butterfly's cell on the free list. It's a bit strange that we then crash in GC rather than crashing on access to the butterfly. Maybe it's because deltablue has this perverse pattern of allocating a ton of arrays using "new Array()" syntax, which happens to trigger this bug. Once I realized that this is the scenario, I was puzzled why it didn't show up in other tests. Turns out this is oddly difficult to trigger, because you need to do enough array allocations that you trigger slow path on average twice (because you have a 50% chance of doing GC in the butterfly allocation, which would be fine). On top of that, you can't let those array allocations die immediately, because if they do, then it's OK that a subsequent sweep reuses their space. Probably none of our other tests managed to make this happen. Hopefully I can fix that. Anyway, this implies that the bug is either in the conservative scan or it's some block management goof that I overlooked. I'll investigate!

Well the initial performance does not look good at all: Benchmark report for Octane on murderface (MacBookPro11,5). VMs tested: "TipOfTree" at /Volumes/Data/secondary/OpenSource/WebKitBuild/Release/jsc (r203920) "AuxButterflies" at /Volumes/Data/primary/OpenSource/WebKitBuild/Release/jsc (r203920) 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.

Comment 35 2016-07-30 18:44:02 PDT

I bet that the problem is how we round up array lengths. I think it causes the butterfly to usually waste once slot at the end of it.

I fixed the accounting. Now I have a splay speed-up but lots of other things are regressed. I think it's because we have internal fragmentation, and I'm working on fixing that.

What I'm consistently finding is that the benchmarks that have regressions are also now using less memory. That makes this feel like a win rather than a loss. I'm going to see what happens when I run things in the full browser.

It looks like there are two things causing MarkedSpace to be a regression: - MarkedBlocks are small, while CopiedBlocks are large. The large size of CopiedBlocks makes a huge difference for certain common allocation sizes, like arrays of length 1024. The allocation size for a contiguous butterfly would be 8200 bytes, which is more than half of a 16KB MarkedBlock. So, we waste 16384-8200=8184 bytes for every 1024 array allocation, unless we make MarkedBlocks larger. But if we make MarkedBlocks larger, we suffer fragmentation because of the very simplistic arrangement of size classes. We should probably use exponential size classes rather than linear ones. - Free-list creation is expensive. In CopiedSpace we are optimized for the case that lots of objects all die at once, which happens to be how the web works. Usually, you don't have to do any work to deal with the fragmentation in a CopiedBlock. You just bump-allocate in a freshly allocated one, or one that has just been zeroed and nothing else. But in MarkedSpace we have to create free-lists. I think we should explore adding something different than free-lists in MarkedSpace. I'm even thinking about making the allocation fast path be a bump/free-list hybrid, and modifying the sweep to quickly identify completely free MarkedBlocks. If a MarkedBlock is completely free then we can tell the allocation fast paths to use bump. Bump can be the default. We could even make it the only inline fast path in some cases. Anyway, here are the current perf results, after I made the MarkedBlock size 64KB: Benchmark report for Octane and Kraken on murderface (MacBookPro11,5). VMs tested: "TipOfTree" at /Volumes/Data/secondary/OpenSource/WebKitBuild/Release/jsc (r204055) "AuxButterflies" at /Volumes/Data/primary/OpenSource/WebKitBuild/Release/jsc (r204055) 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.

Comment 57 2016-08-05 16:05:31 PDT

Here's a good illustration of the trade-offs that I'm trying to resolve by rewriting how we do large allocations. If I just allocate butterflies in marked space, things go bad because many butterflies are just larger than sizeof(MarkedBlock) and so they hit our disastrous large allocation path. The AuxButterflies16KB version makes things a bit better by at least cleaning up the size classes, but this isn't enough to avoid slow-downs on Octane and Kraken. Increasing the block size to 64KB does reduce the slow-downs in Octane and Kraken but it creates a slow-down in SunSpider, probably because we now allocate more memory right out of the gate. So, I think we want a hybrid of AuxButterflies16KB and AuxButterflies64KB, where we allocate small marked blocks but don't waste memory for large butterflies. To do that we need a new large allocation path! Benchmark report for SunSpider, Octane, and Kraken on murderface (MacBookPro11,5).

Things are getting better. But I undid the splay speed-up. I'll investigate what happened there. Benchmark report for SunSpider, Octane, and Kraken on murderface (MacBookPro11,5). VMs tested: "TipOfTree" at /Volumes/Data/secondary/OpenSource/WebKitBuild/Release/jsc (r204128) "SimpleAuxButterflies" at /Volumes/Data/quartary/OpenSource/WebKitBuild/Release/jsc (r204128) "AuxButterflies64KB" at /Volumes/Data/primary/OpenSource/WebKitBuild/Release/jsc (r204128) "AuxButterfliesLargeAlloc" at /Volumes/Data/quinary/OpenSource/WebKitBuild/Release/jsc (r204128) Collected 10 samples per benchmark/VM, with 10 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.

I wanted to know where the remaining performance deficit came from. I was wondering if maybe the choice of size classes played a role. It seems that Octane *really loves* the old size classes, but everything else prefers the new ones. ExpSizeClasses = whats in the patch DirectOldClasses = the patch but with old size classes IndirectOldClasses = like DirectOldClasses but with the size classes tweaked to optimize block packing VMs tested: "TipOfTree" at /Volumes/Data/secondary/OpenSource/WebKitBuild/Release/jsc (r204128) "ExpSizeClasses" at /Volumes/Data/quinary/OpenSource/ExpSizeClasses/WebKitBuild/Release/jsc "DirectOldClasses" at /Volumes/Data/quinary/OpenSource/DirectOldClasses/WebKitBuild/Release/jsc "IndirectOldClasses" at /Volumes/Data/quinary/OpenSource/IndirectOldClasses/WebKitBuild/Release/jsc 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.

I still need to measure the in-browser performance effect of this change. I still need to measure perf on ES6 benchmarks. Here are some things that I can try to improve the perf: - Find users of heapCell->heap()/vm() that can be changed to heapCell->markedBlock().heap()/vm(). - Make totally empty blocks available for reuse by any size class. - Enable some kind of allocator that doesn't sweep.

Comment 64 2016-08-08 13:58:45 PDT

I think that in addition to concurrent sweeping we want to add a bump allocator as well. The concurrent sweeper matches the incremental sweeper's algorithm, in the sense that it will free blocks that are completely empty. But that means that later, we will have to produce a new free list for the block. So, we probably want to move to a world where a freshly allocated block does not need to be swept. That means enabling a bump allocator. Weird.

Holy cow, the concurrent sweeper looks super promising! Speed-ups on raytrace and deltablue. But that's with block freeing totally disabled. Enabling it seems like a bad idea for perf, unless we add a bump allocator. Also, it looks like I need to make sure that the concurrent sweeper only uses one thread. There are still some bugs. I'll fix the bugs and then get back to: - Cap the number of threads that the concurrent sweeper uses. - Implement the bump allocator.

Looks like concurrent sweeping is having a decisively positive effect in Octane, but it still slows down some things. This is with the sweeper hacked to run only one thread and to avoid freeing blocks. We can turn freeing blocks on when if add a bump allocator, or if we make the sweeper free blocks only after they have sat around for a while. I'm hopeful that this will remove any slow-downs, because I think that the slow-downs are caused by the sweeper having to do work that potentially interferes with the mutator, in terms of both memory traffic and lock contention. Now I need to try the following things: - Play a bit more with some data gathering to see what is going on in regressed tests. For example, maybe it's just a matter of tuning how we deal with lock contention. - Implement a bump allocator that we will use when a block is completely empty. Optimize the sweeper for detecting completely free blocks.

Next steps: - Figure out the 10% ai-astar slow-down. This seems like something I could easily fix. It seems to be specific to bump'n'pop. It's probably FTL-related, since the slow-down goes away with FTL disabled. - Determine WTF is happening in SunSpider, and if it even matters when we run in browser. Probably 2d-cube regression is real but that's not enough to explain everything. - Run more benchmarks, like PLT, Speedometer, and ES6SampleBench. - Tighten up the FTL allocation paths. I think that we want the FTL allocation path to be a patchpoint. - Explore sweeping totally empty blocks eagerly, and having a fast block reuse path. - Maybe just finish eradicating copied space in this patch, since there's a chance that when we remove copying entirely, we'll get a bigger speed-up. - Look at larger marked blocks again. - Measure time spent in allocation slow paths in SunSpider. It would be great to know if the allocation time went up! Also measure the allocation time when we don't bottom out in the GC.

Created attachment 286050 [details] the patch Making more changes to remove accidental inclusion of so much JSC stuff from outside JSC. I'd rather fix these issues as they arise rather than work around them.

Actually, I don't think we want to! 0xbbadbeef, and anything that ends in beef, will not pass the JSC cell check, since if the second-lowest bit (0x2) is set, then we assume that it might be a false-true-undefined-null value. We could do 0xbbadbeef * 16, aka 0xbbadbeef0, or even 0xbadbeef0. But on 32-bit, that could be an actual pointer value. That's sort of why I picked 666 * 8.

Comment 129 2016-08-15 21:29:06 PDT

I found the bug. It's not a big deal: concatMemcpy was assuming it could memcpy from a Undecided array to a non-Undecided array, which doesn't actually work, since the Undecided array has garbage in it. This code just needed an extra check.

I forgot to reply to this earlier. My plan is to do one patch per client of CopiedSpace. Next up are typed arrays. I started with butterflies because I knew they would be hardest, but it's still possible that the typed array patch will turn into another ordeal! ;-) The current list of clients is: enum CopyToken { TypedArrayVectorCopyToken, MapBackingStoreCopyToken, DirectArgumentsOverridesCopyToken };

Comment 139 2016-08-16 19:18:39 PDT

Well it looks like I'm going to have more pain to deal with. The patch is a ~2% Speedometer regression. :-( It looks like I can get rid of some of that regression by enabling LargeAllocation for smaller sizes. I'm playing with that right now.

Comment 169 2016-08-24 21:46:15 PDT

It looks like the membuster regression was due to changing the blockSize to 16KB. I'm going to examine in greater detail what the performance is across a bunch of benchmarks with smaller block sizes. I'm going to try 16KB and 4KB. I also want to know: - What's the peak memory usage in Speedometer and JetStream with tip of tree and the various versions of this patch? - How much of the perf loss for smaller blockSize settings is because we no longer have the MarkedBlock cache? Maybe the differences in perf arise from bmalloc quirks that could be sidestepped if we allocated directly from the OS.

FWIW, at the time I removed the MarkedBlock cache, the result was perf-neutral. In bmalloc, all allocations <= 32kB allocate from a reasonably fast path. Perhaps smaller block sizes punish large-ish objects, since so few objects fit per block? If so, maybe we can get a speedup from variable block sizes. Or maybe smaller block sizes waste more space in the metadata region?

If the configuration that runs slower is the configuration that returns more memory to the OS, maybe it's the memory returning that causes the slowdown. You can test this theory by comparing (small blocks) vs (small blocks with bmalloc::Heap::scavenge() changed to do nothing). For example, if the concurrent scavenger runs too soon, even while the benchmark is still touching pages, maybe that's a slowdown, and 64kB blocks avoids the slowdown by making all the blocks unreclaimable.

If so, maybe we can get a speedup from variable block sizes. All tested configurations have a large allocation cutoff at 400 bytes. > > Or maybe smaller block sizes waste more space in the metadata region? I did the math at some point at this seemed negligible. Also, smaller block sizes consistently yield lower memory usage. I'm seeing significant membusyer progressions from 4KB block sizes.

I'm really sympathetic to using malloc under the collector. But if I start messing with the lifecycle of MarkedBlocks, I think we will want to go back to using PageAllocation or similar.

It looks like the problem is that clearing mark bits takes a *lot longer* when the blockSize is 4KB. Theories: - Clang appears to emit an actual call to memset (or a specialized friend, not sure yet) when 64KB, but emits an inline sled of stores when 4KB. Maybe the memset is doing non-temporal stores or some other optimization to amortize the cost? - Could be as simple as the bits being further apart. We could put the bits in a table on the side if we knew for sure that this was the problem. I think that other things may also be taking longer, but I haven't fully investigated those yet.

Sure -- but even then, you'll want to know if returning memory to the OS is an important bottleneck, since you'll have to reproduce that behavior.

64bytes * 8bitsperbyte * 16bytesperatom = 8kB. So, any block size less than 8kB wastes part of the mark bit cache line.

Here's a basic stat that demonstrates the problem with small blockSizes: Time to full GC in Octane/splay with 64KB blocks: about 11ms. Time to walk all blocks to read their hasAnyMarked bit with 4KB blocks: about 4ms. This is why 4KB is slower. Basically any scan of the marked blocks takes a super long time. On the other hand, the "convergence" part of GC - where we do the bulk of our marking - still takes almost exactly the same amount of time as before.

With 64KB blocks, this takes about 0.347162 ms. That's about right. 4ms * 4KB / 64KB = 0.25.

Comment 179 2016-08-25 15:22:55 PDT

All of these problems happen when we enumerate over all MarkedBlocks, not when we find a MarkedBlock by way of some owning object - that part is just as fast with 4KB as 64KB. The solution is clear: move all, or almost all, of the MarkedBlock meta-data into a table on the side. MarkedBlock would no longer be a doubly-linked list node. That part probably contributes to the badness. MarkedBlocks would instead be listed in a Vector<> or similar. This Vector<> would not directly hold MarkedBlock*. Instead it would hold a MetaMarkedBlock, which would contain most of what MarkedBlock currently has in its header: the mark bits, the WeakSet, etc. MarkedBlock would have a pointer back to its MetaMarkedBlock. In this world, MarkedBlock would also have a direct pointer to VM, so that those queries can still be fast. This way, the random-access case of touching MarkedBlocks would be penalized by one indirection but in return it would get some locality. I think this will make no difference in that code, since that code is bottlenecked on function calls, some random checks, and a CAS. But the MarkedBlock scans would become a lot faster. Everything would be in one place!

Comment 180 2016-08-25 15:25:21 PDT

Oh, and we should have a list of active WeakSets. Right now we pay a big price to walk all MarkedBlocks just to find the ones with WeakSets. That's silly! When a WeakSet becomes non-empty, it should shove itself into the global list of active WeakSets. That list can be pruned during collection. In splay, this would make a huge difference. We pay a big price for walking those MarkedBlocks to find WeakSets, even though there are only about 30 active WeakSets and over 50,000 blocks.

Filip Pizlo

Comment 181 2016-08-26 09:08:08 PDT

I've implemented a m_activeWeakSets vector. That speeds things up significantly. However, we still have the following problems: - Clearing mark bits takes a long time. - Snapshotting marked space takes a long time. I believe that snapshotting takes a long time because the way we find marked blocks is by traversing a doubly-linked list, which means that each step along the way is a TLB and cache miss, or even a page fault if we're under stress. All of this can be wished away if we store the meta-data for a MarkedBlock separately from the bock itself.

Filip Pizlo

Comment 182 2016-08-26 09:45:29 PDT

Unfortunately, accessing the mark bits via an indirection appears to be a 5% slow-down over base 4KB. It increases GC time significantly. So, I'm not sure we want this. I'm considering this approach: - MarkedBlock is split into "MarkedBlock" and "MarkedBlock::Meta". The block itself holds the mark bits, a version number, a pointer to the meta, a VM pointer, and the cells themselves. The meta holds all other information. We could put hasAnyMarked in either place, but maybe the block itself would be best. - We reset mark bits lazily. The first step of marking will be to compare the block's version to the current heap version. If different, perform the clearMarks step before proceeding. The use of data-on-the-side would speed up all block walks, which includes: - Block snapshotting. - Eden markbit clearing. The use of the version number would speed up full markbit clearing. Hopefully, by avoiding the pointer-chasing inherent in mark-bits-in-meta, this will not slow down marking as much.

Fantastic news! Adding a version check in testAndSetMarked is perf-neutral! I added a compare-branch in the testAndSetMarked path that does basically this: if (markedBlock->m_version != slotVisitor->m_version) callSlowPath(); We execute this on all paths leading into this code.

The crappy thing about this is that callSlowPath() needs to do locking, and the whole thingy needs a load-load fence: if (condition) slowPath() loadLoadFence() Otherwise, you get crazy race conditions. Hopefully this doesn't get in the way of perf. I'm still testing this code in Debug, so I don't have any perf data yet.

Comment 190 2016-08-28 17:14:37 PDT

It looks like even with a log of hacks, the 4KB version of the code still underperforms the 64KB by a lot, especially on splay. I think I found one area that could be improved a ton. We spend a lot of time sweeping blocks that are 100% full! Probably, sweeping those blocks is much cheaper when the work is amortized. We can get around this by having the SlotVisitor track the number of objects marked in each block. When the count reaches a certain threshold, it can remove the block from the list of blocks that we would sweep.

And the obvious problem with this is that we'd now have two atomic memory operations in MarkedBlock, rather than just one. Ouch! We could actually make this count racy. This is intriguing. It would at worst undercount the population in the block, but with some useful rules: - If a block is empty then the count will definitely be zero. - If a block is non-empty then the count will definitely be non-zero. - The reported count for a non-empty block with N live objects will be between 1 and N, inclusive. This means that we can rely on the count to do what m_hasAnyMarked does currently and we can rely on it for retirement, without using any atomic operations. At worst, the count will be too low, causing us to not retire a block that we should have retired. That's totally fine!

Comment 193 2016-08-29 16:28:44 PDT

Created attachment 287346 [details] sooooooper fast MarkedSpace This amends the code that previously landed with many optimizations to MarkedSpace. Basically, most of the GC is O(num MarkedBlocks). It's funny, and surprising, but true. Of course there is the actual marking phase, which is O(live objects). Usually, the marking phase is long compared to all of the O(num MarkedBlocks) phases, so you don't notice those other phases. Those per-block phases can become expensive because they mean cache+TLB misses on each block! In trunk, this isn't a problem, but moving butterflies into MarkedSpace increases the number of MarkedBlocks without increasing the number of objects. This led to slow-downs that I observed throughout the development of this patch, but that seemed to resolve themselves when I moved to 64KB MarkedBlocks. Of course, that all makes sense. CopiedBlocks were already 64KB. So although CopiedSpace has various algorithms that are O(num CopiedBlocks), you didn't notice it because there were 1/4 as many CopiedBlocks as MarkedBlocks per unit data. Moving that data into MarkedSpace meant quadrupling the amount of per-block overhead for that data. Obviously, benchmarks that allocated a lot of butterflies suffered as a result, but often got faster (due to other optimizations in this patch) if you switches to 64KB. Moving data from CopiedSpace into a super-optimized MarkedSpace is a speed-up when the number of blocks stays the same, but a slow-down when the number of blocks increases. This new patch attacks the problem of per-block costs directly, to enable us to use smaller blocks in MarkedSpace without nearly the same kinds of slow-downs. The optimizations are: - MarkedBlock meta-data is allocated on the side using fastMalloc, so that it can enjoy better cache locality with respect to other MarkedBlock meta-datas, to the extent that the malloc feels it's OK to do it. This makes looping over all MarkedBlocks about 2x faster. - We no longer loop over MarkedBlocks to get to WeakSets. We track the set of active WeakSets: those that have at least one Weak in them. In that set, we separately track those active WeakSets that belong to a MarkedBlock that may have new objects from those that don't. This enables super fast WeakSet scans. - We no longer do anything to clear mark bits! Holy cow! We used block the mark bits and block state behind a 64-bit version number. When the version is older than the current Heap version, we lazily clear the mark bits and set the block state to Marked. So, to clear all mark bits, we increment the version. This removes one of the block scans. - We no longer sort all marked blocks for snapshotting. We know which blocks are in the snapshot, so eden snapshotting only has to walk the blocks with new objects. - We no longer have to sweep retired blocks when allocating! Marking will now track the number of objects in a block on the fly, and when it saturates, it will retire the block. This was a big win because it's common to find a ton of blocks that are full or almost full. The allocator may end up spending lots of time just noting that the blocks are full. Remember, each block is a TLB miss and cache miss all the way to RAM! So, having the marker do it when it already had to touch the darn block for other reasons causes the VM to run faster. I haven't run all benchmarks, but on benchmarks like splay, this seems to basically run as fast as 64KB blocks in the previous patch while using 16KB blocks.

Comment 195 2016-08-30 17:09:16 PDT

Created attachment 287458 [details] fixed the debug assert for real This contains the correct fix. The problem is that previously, we made sweep() put the block in the Marked state if it did not yield a free-list. I think I just did this to make it easier to retire the block. But this is wrong in case sweep() is called with non-null newlyAllocated, for example if we had done stopAllocating() to iterate the heap. In that case, if the sweep() puts the block in the Marked state then it had better preserve the newlyAllocated bits. But sweep() clears those bits. I probably could have fixed that, for example by not clearing the bits if we put the block in the Marked state, but that felt like too much crazy. Instead, I realized that MarkedAllocator should just call didConsumeFreeList() between sweep() and retire(), and if I do this, then I can make sweep() always put the block in the FreeListed state just like before. This felt like a smaller and safer change, so that's what this new version does.

A lot of the performance pathologies that I'm still seeing seem to happen around phase-changes, where we may be switching from using one set of sizes to another. This is bad for our GC right now, since we only rebalance size classes under certain conditions. The next thing I'll try is some way of tracking the set of empty blocks and freeing them at end of GC. Maybe this will work well!

Comment 210 2016-09-03 12:42:11 PDT

I have another idea: what if there is some non-trivial cost that we pay for retirement during marking? There was with 4KB marked blocks. What if that is mostly due to the linked list logic, and the need to grab a lock? The cost here could be significant since we need to touch the two adjacent blocks in order to complete the linked-list removal, and then we need to touch one random block in the retired list. That's lots of spread-out memory! If so, we could change the MarkedBlock list into an array rather than a doubly-linked list. Since it has indices, we could use a bitvector to track "retirement". A block would be "retired" if it's free. In other words, the bitvector should probably have a 1 for blocks that are worth allocating in, and a 0 for those that don't qualify (too full or it's a free index). This would greatly simplify the retirement slow path logic. It may also speed up sweeping in general to have the MarkedBlocks in an array rather than linked together. This isn't totally guaranteed, since we load next() as we're sweeping the block, so the linked list logic during lazy sweep gets the benefit of free cache locality.

Each of those braindumpy sentences summarizes one of the optimizations towards removing the overhead of having many blocks.

It looks like you just store to storageGPR in > m_jit.emitAllocateVariableSized(). You do this in a bunch of places. Yeah, this is part of avoiding forgetting successful butterfly allocations. The control flow here looks like this: void* storage = 0; if (!(storage = tryAllocateButterfly(...))) goto slow; void* result; if (!(result = tryAllocateObject(..., storage)) goto slow; goto done; slow: result = operationCreateNewThingy(storage); storage = result->butterfly; done: Notice that there are two jumps to the slow path, one where the storageGPR is zero, and another when it isn't. This lets the slow path know if we had already succeeded at allocating the butterfly. If we had (storage not null), then it will use that butterfly instead of wastefully allocating another one. If we hadn't (storage is null) then it will allocate one. Hence this move. > > > Source/JavaScriptCore/jit/AssemblyHelpers.h:1433 > > + negPtr(resultGPR); > > Why not move 0? Not the same thing. negPtr(resultGPR) means: resultGPR := -resultGPR > > > Source/JavaScriptCore/jit/AssemblyHelpers.h:1437 > > + addPtr(payloadEndAddr, resultGPR); > > Couldn't this just be a move? Not the same thing. This means: resultGPR := resultGPR + *(payloadEndAddr) So, combined with the statement above, we're doing: resultGPR := *(payloadEndAddr) - resultGPR > > > Source/JavaScriptCore/jit/AssemblyHelpers.h:1440 > > + loadPtr(payloadEndAddr, scratchGPR); > > + addPtr(scratchGPR, resultGPR); > > Why does this load on non-x86 but not on x86? The addPtr(payloadEndAddr, resultGPR) is a load. The load is part of the add. That's something that x86 can do but other instruction sets can't do. Since this code is meant to be used from B3 without blocking off scratch registers, the MacroAssembler's built-in emulation of addPtr(Address, RegisterID) will fail (it needs at least one scratch register). So, we side-step that emulation and do the load/add separately while using our own scratch register.

I removed them! Geoff asked me to remove them, and I forgot. They were only useful during very early stages of testing this patch, so long ago that it feels like a century.

I'm just running through a bunch of tests. - I've run debug+release webkit tests. - I've run debug+release JSC tests. Now I'm running release asan tests. I still have to test 32-bit and ARM.

CC'ing Ryan for the many false positives. But looking at EWS machines, I see a number of flaky assertions that do seem to be caused by this change (and I couldn't quickly find the same on regular bots): Thread 10 Crashed:: WTF Parallel Helper Thread 0 com.apple.JavaScriptCore 0x00000001084676a7 WTFCrash + 39 1 com.apple.JavaScriptCore 0x0000000108070e92 JSC::MarkedBlock::flipIfNecessarySlow() + 114 2 com.apple.JavaScriptCore 0x0000000107648350 JSC::MarkedBlock::flipIfNecessary(unsigned long long) + 64 3 com.apple.JavaScriptCore 0x0000000107647ead JSC::Heap::isMarked(void const*) + 141 4 com.apple.JavaScriptCore 0x000000010766f105 JSC::CodeBlock::visitWeakly(JSC::SlotVisitor&) + 85 5 com.apple.JavaScriptCore 0x0000000107baa2f0 JSC::FunctionExecutable::visitChildren(JSC::JSCell*, JSC::SlotVisitor&) + 368 6 com.apple.JavaScriptCore 0x000000010827b04f JSC::SlotVisitor::visitChildren(JSC::JSCell const*) + 335 7 com.apple.JavaScriptCore 0x00000001082798e5 JSC::SlotVisitor::drain() + 229 8 com.apple.JavaScriptCore 0x0000000108279dc4 JSC::SlotVisitor::drainFromShared(JSC::SlotVisitor::SharedDrainMode) + 1124 9 com.apple.JavaScriptCore 0x0000000107cd243e JSC::Heap::markRoots(double, void*, void*, int (&) [37])::$_0::operator()() const + 734 10 com.apple.JavaScriptCore 0x0000000107cd212c WTF::SharedTaskFunctor<void (), JSC::Heap::markRoots(double, void*, void*, int (&) [37])::$_0>::run() + 28

> Whoa, where did you get this stack trace? :-) I VNC'ed into a EWS bot to find some other crash, and saw this. It occurred a few minutes ago, so it was some new patch running into this crash after the patch was landed. Also, builtin generator test failure: https://build.webkit.org/builders/Apple%20Yosemite%20Release%20WK2%20%28Tests%29/builds/17636/steps/builtins-generator-tests/logs/stdio

Comment 239 2016-09-05 20:23:19 PDT

It triggered an huge amount of compiler warnings with GCC (all the same warning, being #included into a bunch of different source files): In file included from ../../Source/WTF/wtf/StdLibExtras.h:33:0, from ../../Source/WTF/wtf/FastMalloc.h:26, from ../../Source/JavaScriptCore/config.h:54, from ../../Source/JavaScriptCore/b3/B3EliminateCommonSubexpressions.cpp:26: ../../Source/JavaScriptCore/bytecode/Opcode.h:78:54: warning: comparison of unsigned expression >= 0 is always true [-Wtype-limits] #define VERIFY_OPCODE_ID(id, size) COMPILE_ASSERT(id <= numOpcodeIDs, ASSERT_THAT_JS_OPCODE_IDS_ARE_VALID); ../../Source/WTF/wtf/Assertions.h:366:50: note: in definition of macro ‘COMPILE_ASSERT’ #define COMPILE_ASSERT(exp, name) static_assert((exp), #name) ^~~ DerivedSources/JavaScriptCore/Bytecodes.h:33:5: note: in expansion of macro ‘VERIFY_OPCODE_ID’ macro(op_enter, 1) \ ^~~~~ ../../Source/JavaScriptCore/bytecode/Opcode.h:44:5: note: in expansion of macro ‘FOR_EACH_BYTECODE_ID’ FOR_EACH_BYTECODE_ID(macro) \ ^~~~~~~~~~~~~~~~~~~~ ../../Source/JavaScriptCore/bytecode/Opcode.h:51:5: note: in expansion of macro ‘FOR_EACH_CORE_OPCODE_ID_WITH_EXTENSION’ FOR_EACH_CORE_OPCODE_ID_WITH_EXTENSION( \ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ../../Source/JavaScriptCore/bytecode/Opcode.h:79:5: note: in expansion of macro ‘FOR_EACH_OPCODE_ID’ FOR_EACH_OPCODE_ID(VERIFY_OPCODE_ID); ^~~~~~~~~~~~~~~~~~

Comment 240 2016-09-05 20:31:07 PDT

It looks hard to fix. One option is to just silence the warning: #if COMPILER(GCC) #pragma GCC diagnostic push #pragma GCC diagnostic ignored "-Wtype-limits" #endif #define VERIFY_OPCODE_ID(id, size) COMPILE_ASSERT(id <= numOpcodeIDs, ASSERT_THAT_JS_OPCODE_IDS_ARE_VALID); FOR_EACH_OPCODE_ID(VERIFY_OPCODE_ID); #undef VERIFY_OPCODE_ID #if COMPILER(GCC) #pragma GCC diagnostic pop #endif That looks like a mess, but it works.

This isn't bad at all. I think we want to keep the assertion but the presence of the assertion combined with the layout of opcodes guarantees that this assertion will cause the GCC warning. So, I think it makes sense to disable the warning like this. RS=me for this fix.

OK then, it's certainly the easiest solution. http://trac.webkit.org/changeset/205477
