Change SlotSet representation to a variable-sized array of pointers to buckets. The length of the array/number of buckets depends on the size of the page. Before this change the SlotSet always stored a fixed number of buckets. Large pages needed a SlotSet-Array to cover the whole object. Now both regular and large pages both use a single SlotSet object, which contains all bucket pointers.

This is a reland of 4a16305b The original CL adjust only one part of the stack check, namely the comparison of the stack pointer against the stack limit in generated code. There is a second part: Runtime::kStackGuard repeats this check to distinguish between a stack overflow and an interrupt request. This second part in runtime must apply the offset just like in generated code. It is implemented in this reland by the StackCheckOffset operator and a new StackGuardWithGap runtime function. Original change's description: > [compiler] Optionally apply an offset to stack checks > > The motivation behind this change is that the frame size of an optimized > function and its unoptimized version may differ, and deoptimization > may thus trigger a stack overflow. The solution implemented in this CL > is to optionally apply an offset to the stack check s.t. the check > becomes 'sp - offset > limit'. The offset is applied to stack checks at > function-entry, and is set to the difference between the optimized and > unoptimized frame size. > > A caveat: OSR may not be fully handled by this fix since we've already > passed the function-entry stack check. A possible solution would be to > *not* skip creation of function-entry stack checks for inlinees. > > This CL: 1. annotates stack check nodes with the stack check kind, where > kind is one of {function-entry,iteration-body,unknown}. 2. potentially > allocates a temporary register to store the result of the 'sp - offset' > in instruction selection (and switches input registers to 'unique' > mode). 3.

This is the first step in unification of concurrent and main thread marking visitors. The new MarkingVisitorBase will become a base class for all marking visitors and will remove the existing code duplication. This is a refactoring without behavior change.

The `capture_ix` refers to all captures while `capture_count` only refers to named captures. Clarified by renaming `capture_count` to `named_capture_count` and removing the incorrect part of the DCHECK. The `>= 1` part of the condition must still hold since named captures can only refer to explicit capture groups, which start at index 1.

There are a couple of bugs here: 1. The immediate used for vinsertps is wrong when lane == 1, the first two bits specify which element of the source is copied, and it should always be 00, 01 to copy the first 2 lanes of source. 2. For both cases, the second insertps call should be using dst as the src, since dst was already updated by the first insertps call, it was incorrectly using the old value of src. This was probably working correctly because in many cases dst and src happened to be the same register. 3. rep cannot be same as dst, because dst is overwritten, and rep should stay the same I also modified the F64x2ReplaceLane to test separately for replacing lane 0 and lane 1. Fixed bug 3. for arm and arm64. Bug: v8:9728 Change-Id: Iec6e48bcfbc7d27908dd86d5f113a8b5dedd499b Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1877055Reviewed-by:

When inlined allocations are disabled, the space->limit() does not point to the end of the current page. Instead, it points to the current allocation pointer so is the same as space->top(). See how the limit is computed, if heap()->inline_allocation_disabled(), then the limit will be the same as the requested allocation area: ``` Address SpaceWithLinearArea::ComputeLimit(Address start, Address end, size_t min_size) { DCHECK_GE(end - start, min_size); if (heap()->inline_allocation_disabled()) { // Fit the requested area exactly. return start + min_size; } else if (SupportsInlineAllocation() && AllocationObserversActive()) { // ... } else { // The entire node can be used as the linear allocation area. return end; } } ``` If we want to simulate filling up a whole page in the new space, we can instead look at the ToSpace's page_high() which will be the end of the current page in which we're allocating.

The {IsWasmFrame} check in {ComputeLocationFromStackTrace} only returned true for compiled frames, but not for interpreted ones. Thus, for interpreted frames we would run into the code for JS frames, which assumes that a {JSFunction} is available. This CL fixes this issue by renaming {IsWasmFrame} to {IsWasmCompiledFrame}, and introducing a new {IsWasmFrame} method which returns true for both compiled and interpreted frames.
