The cached memory start was not preserved across stack checks in debug code. This only manifests if the stack check is actually executed, hence it's tricky to reproduce.

The code and prototype_or_initial_map fields are marked as weak in the torque definition of JSFunction. Given we don't have any annotations that generate BodyDescriptors or the C++ class specifying weak there didn't reflect in the actual C++ implementation. In the C++ implementation we were treating those as strong pointers and the rest of the code also expects them as strong pointers and doesn't actually deal with cleared weak references. Since JSFunction's header doesn't have any weak references we can just fallback to JSObject::BodyDescriptor that iterates through all header fields and the other JSObject fields as strong pointers. This is what was happening because JSFunction didn't have a body descriptor and we were falling back to JSObject::BodyDescriptor So this is a clean up CL to avoid confusion. There shouldn't be any change in behaviour. So this CL basically: 1. Drops weak from the torque definition to match with implementation 2. Changes JSFunction::BodyDescriptor to JSObject::BodyDescriptor when iterating over objects to be consistent with other JSObjects with strong pointers.

Most Liftoff code comments are generated by the {NextInstruction} function. That code was inside an "#ifdef DEBUG" block so far, because previously code comments were only enabled in debug builds anyway. Now that we have the separate v8_code_comments gn arg, they can also be enabled in release builds. Hence remove the "#if DEBUG" such that code comments are also output in release mode. This should not introduce any compile time regressions since both macros are no-ops in official builds.

Initializing the compilation progress first, and making it an explicit step, allows us to share the wrapper compilation code between async compilation and streaming compilation. In the future it will also allow us to initialize compilation units based on the compilation progress, which will allow us to share more code between async compilation and deserialization.

These changes are found after Cobalt rebased to V8 v8.8. Most changes are grouped into their own CLs and here are the rest. - Replace raw printf with PrintF - Include Starboard as a platform for some implementations - Add some missing headers. This is probably because Cobalt does not compile all of V8 sources so some missing headers are only exposed when compiling Cobalt.

These indicate when a range-based for loop is using an index whose type (value, pointer, or reference) doesn't match what the loop actually extracts from the range. Fix by matching the actual type better. This shouldn't cause any behavior/performance change, just be slightly clearer about what's actually happening when reading the code.

This CL modifies the underlying storage of PerIsolateAssertScope from a bitfield to separate booleans. This slightly increases the space taken by the isolate, but allows for easier access to the individual fields, which is a prerequisite for implementing assertion scopes in TurboFan. It also refactors the template PerIsolateAssertScope class to separate simple C++ scope classes, defined through macros.

We've seen Turbofan take excessive amounts of time for very large functions. As a short-term mitigation, this patch disables optimization for functions larger than 500KB (in their Wasm binary format). Functions of such sizes are rare, so most modules should be unaffected by this patch.
