This adds constant field tracking for arrays. To prevent changing the field in some other elements-kind-branch of transition tree, we only use the const information in the optimizing compiler if the map is not an array map or if the map is stable (since stable maps cannot transition to a different elements-kind-branch without deopt).

V8 test suites return tests by loading them into memory up-front. Up-front loading has memory and loading-time overhead for the testrunner. This CL converts the test-suites to load tests during the test run in parallel. After CL, most test suites start running immediately and all test suites start running after 3 seconds on a modern SSD. This CL eliminates the 200 MiB memory spikes that causes memory problems in mac minis.

This CL adds a method to the factory which converts a stack trace frame represented by a FrameArray plus index, into a StackFrameInfo object. This factory method will later be used to lazily populate stack trace frames when they are retrieved via inspector API. Drive-by: Expose the script id in StackFrameBase.

Toon Verwaest authored
"this" is a very common expression. By using a single ThisExpression object we can both avoid allocating many unnecessary VariableProxies and specialize the resolution of this since we know where it's declared up-front. This also avoids having to special-case "this" reference handling in the paths that would behave differently for "this" than for regular references; e.g., with-scopes. The tricky pieces are due to DebugEvaluate and this/super() used as default parameters of arrow functions. In the former case we replace the WITH_SCOPE with FUNCTION_SCOPE so that we make sure that "this" is intercepted, and still rely on regular dynamic variable lookup. Arrow functions are dealt with by marking "this" use in ArrowHeadParsingScopes. If the parenthesized expression ends up being an arrow function, we force context allocate on the outer scope (and mark "has_this_reference" on the FUNCTION_SCOPE so DebugEvaluate in the arrow function can expose "this"). The CL also removes the now unused ThisFunction AST node. Change-Id: I0ca38ab92ff58c2f731e07db2fbe91df901681ef Reviewed-on: https://chromium-review.googlesource.com/c/1448313Reviewed-by:
