Start nodes for JS functions have the following Parameter node value outputs: closure, ...args_including_receiver, new_target, argc, context This CL adds helper functions for these. There's two interesting gotcha's: - Each Parameter node is associated with an index, starting at -1. Value output indices obviously start at 0, so there's an off-by-one between the value output of the Parameter node, and the Parameter node's associated index. - CSA/Torque graphs use different Start node layouts, yet these are not reflected in compiler logic. There's potential for confusion here. The two layouts should be unified or made explicit. Finally, tests create Start nodes with arbitrary layouts. This blocks removal of methods marked _MaybeNonStandardLayout. In an ideal world, the parameter index would equal the start node output index, and the layout of all Start nodes would be equal. Future work..

Multi byte values get stored on native host order when arrays are being constructed, however as Wasm is LE enforced, they get reversed on BE machines during simd load. This causes incorrect values loaded into vector registers. This CL will force mask elements to be saved in byte sizes to eliminate endianness issues.

(Initially copied from nicohartmann@ CL https://chromium-review.googlesource.com/c/v8/v8/+/2135631) This CL adds a new intrinsic %ObserveNode(expr) which has noop semantics but triggers the new NodeObserver set on the OptimizedCompilationInfo when the node generated for expr is created or changed in any phase (until EffectControlLinearization). This provides the infrastructure to write reasonable unit tests that check for the construction of or lowering to specific nodes (e.g. depending on feedback). When %ObserveNode(expr) is used an object of class ObserveNodeManager is registered to every Reducer/GraphReducer and is notified by the Reducer with all node changes. The same logic is added to classes SimplifiedLowering/RepresentationSelector, which do not inherit from class Reducer. Observed Node modifications currently are: * The Node Operator * The Node type * Node replacements A first use case (cctest/test-sloppy-equality.cc) is included in this CL.

This CL ensures that by moving the recompilation a bit later in the async compilation, to a place where a compile error would have been detected already.

Due to some unusual build failures on some trybots, v8_generate_external_defines_header was reverted to false. This turns it back on but changes the behaviour so that defines are added to the command line as well as to the header. Because the generated header checks that flags that should be unset are actually unset and flags that should be set are either unset or set to 1, this will cause build failures on many types of mismatches, although it will not detect where a flag is not set on the command line when it is set by the header. If no further failures show up with this, the hybrid part can be removed and the v8-gn.h header can stand on its own.

Writing out the number of functions in the module is unnecessary. That number is only used for validation when reading back the value, but only validating that number is pretty arbitrary and does not protect against bugs or attacks.

Holding an unordered set is surprisingly inefficient for large sets. Switching to just a vector makes e.g. deserialization of large modules 30% faster. We pay in terms of memory usage though, so if there is ever a use case where we are storing the same code objects multiple times, we might want do add a deduplication algorithm which cleans up the vector every now and then.

The contract between V8 and Blink is that embedder fields belong to Blink, at least when the object has two or more of them. Now we had 2-3 embedder fields used by the debug proxies and that was confusing Blink, since it expects the first slot to hold an aligned pointer in that case and we had a HeapObject reference stored there. This is a quickfix, which avoids internal fields completely for the context extension proxy (using interceptors on the prototype instead) and changes the named proxies to store the name table under a private symbol instead of using a second internal field. A proper but way more involved fix is to introduce a proper instance type here and use space in the header instead of misusing embedder fields.

This affects: value_type.h, read_value_type(), decoding of relevant opcodes, wasm subtyping, WasmInitExpr, consume_init_expr(), and wasm-module-builder.cc. - In function-body-decoder-impl.h, update rtt.canon to always produce an rtt of depth 0. - Pass a unit32_t type index over a HeapType to all rtt-related utilities. - Remove infrastructure for abstract-type rtts from the wasm compilers, setup-heap-internal.cc, roots.h, and module-instantiate.cc. - Remove ObjectReferenceKnowledge::rtt_is_i31.

When cross-compiling builtins, hardcode the fact that targeting MACOSX enables JSCVT. This is useful when cross-compiling from a x86 Mac where the compiler itself does not define __ARM_FEATURE_JSCVT for the mksnapshot binary.

On most platforms, we can do a single allocation for all code. On platforms where this is not possible (e.g. ARM64 has a 128MB code space limit), we will at least allocate big chunks instead of one chunk per function. This reduces overhead in {WasmCodeAllocator} for maintaining sets of used and available code space, and reduces locking during deserialization. In order to know how much code space to pre-allocate, the serializer writes out the total code space size. This is then used during deserialization to know how much code to expect.
