This CL is part of a series that makes SwissNameDictionary available as a new property backing store. Currently, the flag v8_dict_mode_prototypes allows selecting between NameDictionary and OrderedNameDictionary as the backing store used for all dictionary mode objects. This series of CLs changes this such that enabling the flag causes SwissNameDictionary being used instead of OrderedNameDictionary. The behavior for when the flag is not set remains unchanged (= use NameDictionary). This particular CL just collects many small changes. Note that the changes this CL makes to literal-objects.cc do not fix the problems with the enumeration order of computed property names in classes that currently exist when using OrderedNameDictionary. This will be fixed separately.

WasmJs::Install uses command line flags for feature detection, because the context is not yet available to detect origin trial flags. Exception handling is available via an origin trial, so make sure that the exception constructor is installed regardless of the command line flag.

This CL generalized the previous check that a FunctionTemplateInfo instance is not changed after being instantiated to a check for immutability after being published. A FTI is considered published once it is instantiated (set in a SharedFunctionInfo) or set as an accessor on a JSObject. The published state is tracked in the flags field. TurboFan relies on this immutabilty for concurrent access. The immutability requirement was already met before this CL, but this change enforces this by adding necessary checks.

This adds the possibility to define non-nullable function tables of heap types kFunc and user-defined functions. When such table is defined, it is obligatory to provide an initializer expression after its limits. Currently, this can only be a function reference. Changes: - Change WasmTableObject::raw_type to encode the whole entry type. - Restructure call_indirect to load the signature only if needed, and do null checks only if needed. - Add the requirement to provide an initializer expression for non-nullable tables in module-decoder. - Rename "global initializer" -> "initializer expression" everywhere. - Add table initialization in module-instantiate. - Edit both the C++ and JS WasmModuleBuilder. - Add and slightly improve tests. - Format wasm-module-builder.js.

This CL implements table.fill in Liftoff. For that I also changed the TurboFan implementation to call the runtime through a builtin instead of calling the runtime function directly. This has the advantage that we don't have to convert the parameters to Smi in the generated code.

This series of CLs changes this such that enabling the flag causes SwissNameDictionary being used instead of OrderedNameDictionary. The behavior for when the flag is not set remains unchanged (= use NameDictionary). This particular CL a) moves two operations from ordered-hash-table.cc to swiss-name-dictionary.cc (which were itself just copies of existing functions, see the existing TODOs about cleaning this up). b) adds a new getter for the SwissNameDictionary backing store, called JSReceiver::property_dictionary_swiss. c) contains a first wave of replacing usages of OrderedNameDictionary with SwissNameDictionary.

This adds support for WasmGC objects (structs/arrays) to the inspector backend. For prettier printing, it also adds support for reading the "type" and "field" subsections of the "name" section in Wasm modules. This patch includes a revert of most of commit crrev.com/987a7f4a because types are more complicated now.

Now that Goma is part of depot_tools (and any stale standalone checkouts in ~/goma are dysfunctional), update gm.py's detection logic. Note: this only affects new args.gn files created by gm.py. On machines where the build is already set up, this has no effect.

This refactors the way the function-body-decoder maintains its value stack: it now always calls the respective instruction's interface function before updating its value stack (by dropping input values and pushing results). The benefit is that interface functions still see the original values in the decoder. No change in observable behavior is intended.

When disposing the compilation jobs, we have to update some fields on JSFunction. Though the current implementation is safe given we only dispose the compilation jobs when main thread is blocked, it is still cleaner and safer to dispose of these jobs only on the main thread. That also unifies the way we handle flushing the queues when we want to block waiting for the pending tasks to finish or not Basically this cl flushes the input queue before waiting for any pending tasks to finish. This would avoid the special handling on the background threads that dispose of these jobs when we are in the flushing mode. This also means we don't need to keep track of the mode anymore.

This removes many wasm-specific code paths from codegen, such that includes from src/wasm can be removed. After src/wasm is fully excluded from no-wasm builds, we can also clean up unused enum values, but for now they are still being referenced.

This is a reland of fab754ff. The lock-order inversion is fixed by putting the old code into the surrounding WasmCodeRefScope such that it gets deleted only after releasing the mutex.

Previously, we recorded pairs of (bytecode offset, sparkplug pc) to create a mapping of bytecode offset <-> sparkplug pc. These pairs were only recorded after builtin/runtime calls. In preparation for deoptimizing to Sparkplug, we need a more precise mapping. With this CL, we record positions for every bytecode. Instead of storing a pair of (bytecode offset, sparkplug pc), we store only the pc, calculating the bytecode offset from the index in the mapping table. For easier use an iterator to access the mapping is introduced. Drive-by: Reduce sampling interval in cpu-profiler cctest to get rid of flaky failures.
