This CL is a prepatory step towards moving the stack locals blacklist from the DebugEvaluateContext to the respective {ScopeInfo} objects. The locals blacklist is used during local debug evaluate to decide whether a context lookup can advance the context chain upwards, or if lookup needs to stop at the current scope. This CL also introduces a "Recreate" static helper method, that allows an existing ScopeInfo to be cloned, but with a locals blacklist attached. This will be needed since blacklists are only created on-demand during debugging.

For each wasm feature flag, this adds a link to the proposal repository, and states who is the v8-side owner of the implementation. For stated and shipped features, it also sais since which v8 version this is the case. It also adds some documentation about the meaning of the three categories (experimental, stages, shipped).

This change is the first part of adding Torque support for a "bitfield struct", which represents a set of bitfields packed together into an integer value. With this change, Torque can generate the list of BitField template specializations that allow runtime code to use the bitfield values. The flags used in SharedFunctionInfo are converted to Torque to exercise this functionality. Bitfield values are not yet accessible directly from Torque code.

This is a reland of 5bddc0e1 The original CL was speculatively reverted as it was suspected to cause failures on the non-determinism bot. This was ultimately confirmed to not be the case, so this CL is safe to reland as-is. Original change's description: > Implement top-level await for REPL mode > > Design doc: bit.ly/v8-repl-mode > > This CL allows the usage of 'await' without wrapping code in an async > function when using REPL mode in global evaluate. REPL mode evaluate > is changed to *always* return a Promise. The resolve value of the > promise is the completion value of the REPL script. > > The implementation is based on two existing mechanisms: > - Similar to async functions, the content of a REPL script is > enclosed in a synthetic 'try' block. Any thrown error > is used to reject the Promise of the REPL script. > > - The content of the synthetic 'try' block is also re-written the > same way a normal script is. This is, artificial assignments to > a ".result" variable are inserted to simulate a completion > value. The difference for REPL scripts is, that ".result" is > used to resolve the Promise of the REPL script. > > - ".result" is not returned directly but wrapped in an object > literal: "{ .repl_result: .result}". This is done to prevent > resolved promises from being chained and resolved prematurely: > > > Promse.resolve(42); > > should evaluate to a promise, not 42. > > Bug: chromium:1021921 > Change-Id: I00a5aafd9126ca7c97d09cd8787a3aec2821a67f > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1900464 > Reviewed-by: Yang Guo <yangguo@chromium.org> > Reviewed-by: Leszek Swirski <leszeks@chromium.org> > Reviewed-by: Toon Verwaest <verwaest@chromium.org> > Commit-Queue: Simon Zünd <szuend@chromium.org> > Cr-Commit-Position: refs/heads/master@{#65273} TBR: yangguo@chromium.org,verwaest@chromium.org Bug: chromium:1021921 Change-Id: I95c5dc17593161009a533188f91b4cd67234c32f Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1954388Reviewed-by:

Currently a TracedNode of a TracedReference is freed only if its target V8 object is unreachable. This is problematic for TracedNodes created for long-living (or immortal) V8 objects and leads to memory leaks. This CL adds logic for collecting unreachable TracedNodes: 1) Each TracedNode gets a markbit. Initially the markbit is set (i.e. we have black allocation for TracedNodes). 2) During marking RegisterEmbedderReference sets the markbit of the corresonding TracedNode. 3) In the atomic pause of Mark-Compact when TracedNodes are iterated, we check the markbits and free TracedNodes with cleared markbits. After this processing all markbits are cleared for the next GC. Note that the new logic does not apply to TracedNode that have callbacks and/or destructors.
