Currently we clear only old-to-new slots in the sweeper. For old-to-old slots we maintain the invariant that there are no recorded slots in dead objects by explicitly clearing them on object size change and array trimming. The write barrier for concurrent marking will record slots even when the host object is white. Thus, it can introduce slots in dead objects, which will break evacuation phase if we do not clear them in the sweeper. Besides that, the patch makes handling of slots more uniform and allows us to remove clearing of slots on object size changes.

Function-granularity coverage skips functions that are both uncovered and have an uncovered parent. This optimization needs to be tweaked once block coverage and incremental collection is in play, as it is possible to have a function with invocation_count == 0 (i.e. uncovered at function granularity) that still has relevant block-granularity coverage.

in preparation for caching StoreIC-Transition handlers in there. This CL should not change behavior or performance. The TransitionArray class no longer serves a dual purpose; it is now simply the data structure serving that role. Further, it now supports storing transitioning handlers in its "target" slot, which in turn have a WeakCell pointing to the transition target (but this functionality is not being used yet). The interface for accessing a map's transitions, previously implemented as a set of static functions, is now handled by the TransitionsAccessor class. It distinguishes the following internal states: - kPrototypeInfo: map is a prototype map, will never cache any transitions. - kUninitialized: map can cache transitions, but doesn't have any. - kWeakCell: map caches a single transition, stored inline. Formerly known as "IsSimpleTransition". - kFullTransitionArray: map uses a TransitionArray to store transitions. - kTuple3Handler, kFixedArrayHandler: to be used in the future for caching transitioning handlers.

Add UseScratchRegisterScope for MIPS and use it instead of using at register directly. Original commit message: `Introduce a stripped down version of UseScratchRegisterScope for ARM and use it inside the assembler and macro-assembler. At the exception of the Call instructions, we now use this scope instead of using the ip register directly. This is inspired from how the ARM64 backend works. In general, the benefit of doing this is we can catch cases where ip is being used both by the caller and by the assembler. But more specifically, TurboFan reserves r9 as an extra scratch register because ip can already be used by the assembler. With this utility, we can isolate the cases in the code generator which need an extra register and potentially fix them, allowing us to give r9 back to the register allocator. This patch uncovered places in the assembler where we were using ip unconditionally when we could have re-used the destination register instead.` Bug: Change-Id: I1a35c1661579882801605337abfc95f75b47f052 Reviewed-on: https://chromium-review.googlesource.com/574923 Commit-Queue: Ivica Bogosavljevic <ivica.bogosavljevic@imgtec.com> Reviewed-by:

Rather than storing the isolate in compiler dispatcher jobs, which gets weird for jobs that are entirely off-thread, instead pass the isolate in when stepping on the main thread. This makes it clearer which steps must be executed on the main thread, as they require the caller to explicitly give them access to the isolate.

With TurboFan, there should no longer be any deopt loops (aside from bugs). So, the "too many deopts" bailout is no longer needed, at least in its current form. This fixes an issue where deopt counts are leaked between native contexts, resulting in optimization being disabled unnecessarily.
