This changes a few bits about how continuation counters are handled. It introduces a new mechanism that allows removal of a continuation range after it has been created. If coverage is enabled, we run a first post-processing pass on the AST immediately after parsing, which removes problematic continuation ranges in two situations: 1. nested continuation counters - only the outermost stays alive. 2. trailing continuation counters within a block-like structure are removed if the containing structure itself has a continuation.

This CL does two things: 1. It introduces Call/JumpCodeObject as the bottleneck for all calls to non-heap-constant Code objects; and 2. it dispatches directly to the off-heap entry point for all embedded code. Codegen at runtime remains unchanged to preserve the shorter, branch-less calling sequence.

Before computing the merge state, compute the list of free registers. This list is used when we need a register for ensuring single register use. It avoids picking a register which is in use by a not-yet-visited merge slot, which would then have to be moved to another register or to the stack. On epic, this saves ~10.5% generated code size in Liftoff.

This silences the new presubmit check for the whole src/wasm directory. This change uncovered that MSVC is a bit behind with noexcept annotations on standard containers. This makes all implicit constructors and assignment operators noexcept(false) if the class contains any standard container. Thus disable noexcept on MSVC for now.

This replaces another use of std::vector. Stack states (consisting of locals plus operand stack) are also typically small, thus optimize for those cases.

This fixes a bug from 0400fc20, which assumed that we can set the markbits and the marked descriptors counter independently. This does not work because the Scavenger skips slots recording for non-black promoted objects. The fix is to mark the descriptor array black whenever we change the marked descriptors counter.

The simulated C++ signature for generated code entry points should rely on primitive values (as opposed to ObjectPtr). Bug: v8:3770 Change-Id: I6f6f4dc8a93c7ba46bfc7052dc4745b16e9fd62f Reviewed-on: https://chromium-review.googlesource.com/c/1386875Reviewed-by:

Avoid named constructors for Value and Control and the hack to also have them on subclasses. Instead, add a new template type and a constructor to create the subtype from this template. Instead of the named constructors on the subtype, we now create a template and initialize the subtype from the template.

The V8_NOEXCEPT annotation is not needed for deleted class members. Also our DISALLOW_COPY_AND_ASSIGN macro does not add it there. Additionally, include the file name to find the reported location more easy.

This simplifies NextArrowFunctionInfo, allows us to Scope::Snapshot::Reparent directly rather than moving it, and allows us to skip reparenting in the simple parameter arrow function cases. This CL additionally fixes arrow function name inferring. Change-Id: Ie3e5ea778f3d7b84b2a10d4f4ff73931cfc9384a Reviewed-on: https://chromium-review.googlesource.com/c/1386147Reviewed-by:

Forgetting V8_NOEXCEPT annotations on copy constructors, move constructors, copy assignment operators or move assignment operators can cause subtle performance bugs or compilation failures, sometimes only on specific architectures or compilers. Thus check that all those special class members are marked V8_NOEXCEPT. This check is only executed on modified files for now, and can be bypassed. Please report any false positives on the associated bug.
