This allows the compiler to eliminate more unneeded branches. Since all functions just do a lookup in a static table (either directly, or via compiling a switch to such a lookup), they are also good candidates for inlining, which is made possible by this change. One DCHECK is removed instead of pulling in the inl header, which would require more refactoring since the check is in a non-inl header.

GCMole now comes with the long forgotten use-after-free detection enabled by default. The CL also improves error logging when test expectations mismatch with the actual output and updates the hash of GCMole to be used with the newly built version with enabled UAF detection. The CL also contains an ignore for isolate.cc due to inability to fix a warning there and fixes a couple of UAF warnings.

The IsInBounds function is used in a few different places, when used for bounds checks on 32-bit platforms, size_t for max_memory_size leads to incorrect out of bounds accesses as size_t is not guaranteed to be 64-bit on all platforms. Use specific uint32_t, uint64_t methods for Wasm bounds checking instead of size_t.

Prototype f32x4.trunc on ARM for both ARM v7 and ARM v8. ARM v8 has support for vrintz, and for ARM v7 we fallback to runtime. Since ARM v8 uses vrintz, which is the same instruction used for F32 trunc (scalar), wasm-compiler reuses the Float32RoundTruncate check.

Currently, atomics operations are only allowed on shared memory and are enabled on regular memory behind the --wasm-atomics-on-non-shared-memory flag. Set the default value of this flag to true. This enables the following behaviors: - No validation failures when atomic opcodes are used on wasm memory backed by ArrayBuffers - memory.atomics.wait{32/64} operations will trap when wasm memory is not shared - memory.atomics.notify will always return 0 if wasm memory is not not shared.

This change enables automatic generation of Cast<> operators for classes that are defined in Torque. * Cast<> macros are generated for all classes that are defined in Torque code that are neither shapes nor marked with a new @doNotGenerateCast annotation. * Implicitly generated Cast macros simply call through to an internally-defined "DownCastForTorqueClass" macro that implements the cast using one of three strategies for efficiency. If the class has subclasses (i.e. a range of instance types including subtypes), the DownCastForTorqueClass checks for inclusion in the instance type range. If the class has a single instance type (i.e. no subclasses), then either 1) a map check is used if the class has a globally- defined map constant or 2) an equality check for the instance type is used. * Added new intrinsics to introspect class information, e.g. fetching instance type ranges for a class, accessing the globally-defined map for a class. * Removed a whole pile of existing explicit Cast<> operators that are no longer needed because of the implicitly generated Cast<> macros. * Added tests for the new Cast<> implementations.

Chrome may send memory measurement requests to multiple renderer processes at the same time. This may lead to multiple GC happening at the same time if the processes are idle. Randomization spreads out the GCs over time to reduce the load on the system.

This changes the use of "sane" to "sensible" or "valid". I tried to be sensible in my choice of replacement, by trying to read the comments or code to see which word matches the intention closest.

Prototype f32x4.floor on ARM for both ARM v7 and ARM v8. ARM v8 has support for vrintm, and for ARM v7 we fallback to runtime. Since ARM v8 uses vrintm, which is the same instruction used for F32 Floor (scalar), wasm-compiler reuses the Float32RoundDown check.
