V8 provides ScriptCompiler::CompileFunctionInContext method which takes expression and compile it as anonymous function like (function() .. expression ..). To produce correct locations for stmts inside of this expression V8 compile this function with negative offset. Instead of stmt position blackboxing use function start position which is negative in described case.

Instead of allocating and embedding certain heap numbers into the code during code assembly, emit dummies but record the allocation requests. Later then, in Assembler::GetCode, allocate the heap numbers and patch the code by replacing the dummies with the actual objects. The RelocInfos for the embedded objects are already recorded correctly when emitting the dummies.

This reverts commit c5aad5f2 The CL was reverted due to missing Chromium dependencies. This commit removes the simulator trace-based tests, and the associated header file dependencies, previously pulled in by DEPS. The NEON support now has only hand-written tests, in test-assembler-arm64.cc. The remaining tests can be added in a later patch.

This removes any kind of heap access from the asm.js validator internals and hence makes it independent of a specific Isolate. It is a precursor towards potentially being able to run validation while streaming.

In current implementation in expressions like await foo() we have break location right after foo call and before actual await. And we additionally have a lot of other statement locations because of do scope. Let's move async debugging closer to sync debugging and introduce only one break location for await - before awaited function call.

The assertion was too strict, not matching the check in JSTypedArray::Create. Delete the TODO because the code does not actually rely on the assertion for safety: EmitElementStore always performs a length check. Drive-by-fix: KeyedAccessStoreMode::STANDARD_STORE is equally safe and does one comparison less.

In TurboFan the ArchDebugBreak opcode is not used for debugging but to force a crash in unreachable or unimplemented code path. The opcode was marked as having no side effects allowing the scheduler to bring it "up" with unfortunate consequences.

This CL improves break locations for expressions like 'var a = <expr>'. Without CL we use <expr> position as break location for initialization statement, with this CL we use position of first character after '=' as position. Benefits (see test for details): - only one break in expressions which includes mix of property lookup and calls, e.g. var p = Promise.resolve().then(x => x * 2), - removed redundant break location for expressions like: let { x, y } = { x: 1, y: 2}.
