Mike Stanton authored
Currently the FeedbackVector uses arrays in slots that are polymorphic, usually in a <map, handler> tuple pattern. Helper functions try to re-use an existing array if it's already in place. For Concurrent TurboFan, it would be far better if these FixedArrays were immutable. We could then count on semantic correctness when harvesting their information from a background thread without locking. Additionally, the arrays should always be initialized fully before being set in place.

We can walk linear prototype chains using iteration instead of recursion, reducing the likelihood (though not excluding the possibility) that large prototype-relation graphs will run into a stack overflow. This partial mitigation should be performance neutral.

Prototype f32x4.nearest on ARM for both ARM v7 and ARM v8. ARM v8 has support for vrintn, and for ARM v7 we fallback to runtime. Since ARM v8 uses vrintn, which is the same instruction used for F32RoundTiesEven (scalar), wasm-compiler reuses the Float32RoundTiesEven check.

Move more logic into the {TraceLine} class. In release builds, this class will not do anything. Since there is no code after the switch in {DecodeOp} any more after this CL, we can apply tail-call optimization (via explicit returns in C++), which will save an additional call in some cases.

Every condition which can only fail on invalid wire bytes should be wrapped in the VALIDATE macro. This way, it will automatically be skipped if {validate} is false, and we will automatically add V8_LIKELY annotations to the branches. Also, consistently use the style if (!VALIDATE(condition)) { ... handle error ... } ... continue ... Drive-by: Remove unnecessary OPCODE_ERROR macro.

Since the interpreter is not used in production any more, it does not need to support lazy compilation.

The more complicated subtyping checks due to the new wasm-gc types caused a performance regression. This CL: - Adds a V8_LIKELY annotation to the more common path (type equality). - Factors the rest of the check out of the inlinable part of subtype checking to reduce binary size, and thus cache misses.

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.

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.

The current memory reservation approach for wasm memory tries to reserve upto the maximum, and only reserves initial if the maximum reservation fails. Add multiple retries with a smaller upper limit so that calls to grow have a higher probability of succeeding.

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.
