Omer Katz authored
This CL adds 2 new values to the EmbedderStackState enum with more explicit names. The old values are updated as aliases to the new values and marked as soon to be deprecated. This CL also moves the enum to v8-platform.h so that it can be reused by cppgc. Depracating individual values in an enum is supported by GCC only since version 6. Thus new macros were needed for the deprecation (which delegate to the existing macros when supported). GCC versions older than 6 are still used by the CQ bots.

Jakob Gruber authored
We don't yet support serialization of optimized code, so whenever the serializer encounters an 'unexpected' Code object, it aborts. Snapshot::ClearReconstructableDataForSerialization does not clear weak links created through compilation dependencies. These links make Code objects reachable even though recompilable data has been cleared from JSFunctions/SFIs/JSRegExps. Forcing a full deopt of the entire isolate is the simple of way of solving this until serialization support for optimized code has been implemented.

Prior to this CL we still implemented a HasProperty-GetProperty sequence when accessing named captures in GetSubstitution. This was briefly part of the spec (we also threw an exception when the property was not present), but since late 2017 the GetProperty call has been unconditional.

This CL is pretty mechanical; I just iterated through some Torque classes making the following changes: - Use @generateCppClass if it seems easy to - Use @generatePrint if the existing printer doesn't do anything special - Fix up any imprecise field types It also includes two minor changes to implementation-visitor: - Add a new -inl.h file with the things needed for torque-generated/class-definitions-tq.cc so we don't need to keep changing the compiler when we add @generateCppClass. - Avoid emitting incorrect accessors for ExternalPointers. This isn't strictly necessary for correctness, as the accessors defined in C++ already hide the ones inherited from generated code, but it makes me feel safer.

If multiple isolates are using the same module, we need to keep it tiered down as long as any isolate still has a debugger open. Also, we cannot short-cut the {NativeModule::TierDown} method, since the previously triggered tier down might not have finished yet. For now, each isolate starts an independent tier down (i.e. a full recompilation). We could optimize this later by skipping functions that are already tiered down, or are already scheduled for tier down, but we still need to wait for tier-down to finish on each isolate.
