Port 808a5d76 Original Commit Message: InterpreterEntryTrampoline checks 1. If there is any optimization marker, and process the marker by calling the correct runtime function 2. If there is any optimized code, it installs optimized code and starts executing optimized code. Earlier it was OK to do these two checks in any order, since it wasn't possible that we have both a marker and optimized code. Turboprop code calls out to IET to process the optimization marker / install next tier optimized code. So we have to check for optimization marker before we check for optimized code.

With the recent switch from the tasks API to the jobs API for thread management within WebAssembly compilation we got the problem that TurboFan compilation of a previous compilation can block the Liftoff compilation of a new compilation. With synchronous compilation, this can cause significant delays for the user. With this CL we increase the priority of synchronous compilation so that at least synchronous compilation can only be blocked by other synchronous compilation. This fixes issues that we saw on autocad. Why is it okay to increase the priority of synchronous compilation? * On the main thread, synchronous compilation is only allowed for small modules which should not take long to compile. Also, the compilation blocks the main thread and should finish as fast as possible. * On worker threads, delaying other background work is not such a big issue. Downsides: * This does not only increase the priority of the initial compilation, but also for the TurboFan optimization. Similar to above, for small modules on the main thread this should not be a big deal because compilation is fast. Big modules can only be compiled on worker threads. Note that this is supposed to be a fix for the problems we see at the moment with autocad on stable and beta. Eventually compilation job management should be done by the wasm engine for all WebAssembly compilation, so that not each WebAssemly module has to do its own compilation job management.

This adds a first simple version of the inspector fuzzer, which is a stripped-down version of the inspector-test executable. The fuzzer generates inputs which are compatible with inspector-test. There are still memory leaks, and the fuzzer will probably run into timeouts most of the time. Both of this will be addressed in follow-ups.

The comment at the beginning of ordered-hash-table.h desribing the layout of ordered hash tables seems to have become outdated. 1. There was a "kPrefixSize + " missing in the description of the left bound of the first non-fixed-sized part in normal and obsoleted tables. The following only affects obsoleted tables: 2. The bucket count doesn't reside at [kPrefixSize + 0], instead it is unchanged w.r.t normal tables, and resides at [kPrefixSize + 2] 3. The next newer table takes place of the element count, residing at [kPrefixSize + 0]. This can be seen by NextTableIndex() being defined as NumberOfElementsIndex() 4. The number of removed holes is never written anywhere when obsoleting a table. Instead, the number of deleted elements count is used for this. This can be see by DCHECK_EQ(table->NumberOfDeletedElements(), removed_holes_index); in method Rehash 5. kClearedTableSentinel is written to the number of deleted element slot when clearing a table, as seen by table->SetNumberOfDeletedElements(kClearedTableSentinel); in method Clear Bug: v8:7569, v8:11074 Change-Id: I0e6750fc57c90b6c09fc41f001cd555f7c455fd3 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2505763 Commit-Queue: Frank Emrich <emrich@google.com> Reviewed-by:

Have a new macro-assembler function Pshufb that does not require dst and src to be equal, since the vpshufb can have 3 operands. On SEE, if dst and src are not equal, emit a movapd(dst, src). This saves a move on AVX. Small cleanup to use kScratchDoubleReg2 instead of requesting for a tmp (x64).

On newer compilers the {operator delete} with explicit {size_t} argument would be instantiated for {v8::BackingStore} and used in the destructor of {std::unique_ptr<v8::BackingStore>}. The {size_t} argument is wrong though, since the pointer actually points to a {v8::internal::BackingStore} object. The solution is to explicitly provide a {operator delete}, preventing an implicitly generated {size_t} operator.

This cl adds support for tiering up in TurboProp. This cl makes necessary changes to support tier up but doesn't tier up yet. More specifically this cl: 1. Introduces a new flag for interrupt_budget_for_midtier and updates code to use the correct interrupt_budget. 2. Introduces a flag turboprop_as_midtier and necessary support to tier up. When this flag is enabled, we introduce checks for tierup and updating interrupt budget.

Extract Shufps to handle both AVX and SSE cases, in the SSE case it will copy src to dst if they are not the same. This allows us to use it in Liftoff as well, without the extra copy when AVX is supported. In other places, the usage of Shufps is unnecessary, since they are within a clause checking for non-AVX support, so we can simply use the shufps (non-macro-assembler).

The idea was to distribute the publish limits to reduce the chance that different tasks are publishing at the same time.

We previously assumed that a fake stack should be mapped back to a real stack based on fake-stack offsets. This is not correct: Fake and real stack are disjoint and both contain the corresponding slot values. For global handles this means that on-stack handles must be registered using their real stack frame base to be able to purge them occasionally based on the current stack address. When dealing with a slot though, the GC can just dereference the slot for a value, indeppendent of whether the slot is in a fake or real frame. Drive-by: Fix tests that do not want stack handles by creating handles on heap.

This commit adds the 'l' (linear) RegExp flag (as in e.g. /asdf|123/l) that forces execution in linear time. These regexps are handled by the experimental engine. If the experimental engine cannot handle the pattern, an exception is thrown on creation of the regexp. The commit also adds a new global V8 flag and changes an existing one: * --enable-experimental-engine, which turns on recognition of the RegExp 'l' flag. Previously this flag also caused all supported regexps to be executed by the experimental engine; this is not the case anymore. * --default-to-experimental-regexp-engine takes over the previous semantics of --enable-experimental-regexp-engine: We execute all supported regexps with the experimental engine.

The main fix here is on non-AVX builds, the shifts require dst == src. Calling macro-assembler functions like Psrlw assumes that we already met that requirement (which we usually specify in TurboFan's instruction-selector). On Liftoff, we need to do that check manually. This is done by using the helper EmitSimdShiftOpImm which will do this check, and dispatches to AVX if supported, or mov if dst != src. Also fix a couple of places where we forgot to annotate the required SSE extension for the instruction.
