This is a reland of commit dac61556 This is a straight-up reland with no changes, because: 1) The failure doesn't reproduce locally 2) The failing flaky test that triggered the revert is not related to the code modified by this CL and should (in theory) not be impacted. Original change's description: > [inspector] Allow Debugger.setScriptSource to edit top-most function > > This CL adds a new boolean flag on the Debugger.setScriptSource CDP > method that gets piped all the way through to the live-edit mechanism. > The new flag enables live-editing of the top-most function while > paused. > > The CL adds a couple of tests that cover the new core use cases for > this flag. > > R=jarin@chromium.org > > Bug: chromium:1334484 > Change-Id: I12fec591b2b6550d89748714620e629548e1b9c1 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3695354 > Reviewed-by: Kim-Anh Tran <kimanh@chromium.org> > Reviewed-by: Jaroslav Sevcik <jarin@chromium.org> > Commit-Queue: Simon Zünd <szuend@chromium.org> > Cr-Commit-Position: refs/heads/main@{#81127} Bug: chromium:1334484 Change-Id: I9a9bf7e03d81c86adb4819b9756dd9afcf6fa021 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3706398Reviewed-by:

This fixes an ODR violation: the macro V8_TARGET_ARCH_ARM64 was only visible when building V8, but not outside it. The CL implements a quick fix that relies on compiler-based macros (__aarch64__). The proper fix would be to make these target macros be part of the public config.

- removed some 'feature envy' instances: - created a AugmentedOptions class to take care of non trivial option look-ups - moved some calculation closer the the actual data - promoted parameter that was passed around a lot (options) to filed in the offending class - similar object creation looks a bit more similar - CommandContext provides a wrapper that ensures resource de-allocation - separate tests from standard and num_fuzz runners - added a couple of more tests to improve coverage This is still in flux. But further changes risk creating a disconnect between the original implementation and further refactorings.

The CHECK was checking that we return the exception sentinel if an exception is pending. The other way is actually equally important: If we return the exception sentinel, a pending exception must be scheduled. Since the CEntry stub assumes that all values returned from runtime functions are valid tagged values (pointing into the JS heap), do also check that. This check would have prevented the linked issue.

Asynchronous WebAssembly compilation returns the compilation result through resolving a result promise. So far the result promise was resolved through V8-internal APIs. This caused problems, because resolving promises requires correct handling of microtasks, and microtasks are controlled by the embedder, and not by V8. This CL adds an API to allow the embedder to resolve the result promise itself, and handle microtasks as necessary. The use of the new API is available in a full CL, without API dance: https://chromium-review.googlesource.com/c/v8/v8/+/3694975 R=cbruni@chromium.org Bug: v8:12953 Change-Id: Ie9a56041f2d3e0c46664f1938e995f1e2c22f981 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3695584Reviewed-by:

The native module cache makes it difficult to test deserialization, because the native module just gets loaded from the cache instead of deserializing the serialized module. This CL adds a new flag, --wasm-native-module-cache-enabled, to control whether the native module cache is enabled or not. The cache gets disabled by handling all modules like asm.js modules when the cache gets disabled, as the cache is not used for asm.js. The name of the flag is positive (i.e. `enabled` instead of `disabled`) to avoid double negation. The flag is true by default, and set to false in tests.
