Currently LdaNamedProperty bytecode for expressions like a.b has position before dot. This CL moves this location after dot. It's important for later removing of Nop bytecodes in expressions like a.b() where a is local variable, property call and property load should have the same position.

This CL refactors the WasmMemoryObject and WasmInstanceObject classes to use WeakFixedArray instead of using a doubly-linked list of instances. This simplifies the lifetime management of instances by not requiring them to be unlinked from this list upon GC. It also simplifies the iteration over the instances using a given WasmMemoryObject. Note that, contrary to my naive assumption at the outset, it is still necessary for the InstanceFinalizer (called upon a WasmInstanceObject death) to unlink itself from a WasmMemoryObject's instances list, due to finalizer ordering.

When there are some changes in the graph, we mark the uses of the reduced node for revisiting. These are pushed onto a stack and hence follow a depth first traversal. This sometimes leads to propogating the changes down the graph and again revisiting the entire graph because of the nodes that were marked for revisit earlier.

This CL introduces TurboAssembler, a super-class of Assembler and sub-class of MacroAssembler. TurboAssembler contains all the functionality that is used by Turbofan and previously was part of MacroAssembler. TurboAssembler has access to the isolate but, in contrast to MacroAssembler, does not expect to be running on the main thread.

This CL refactors the internal representation of JavaScript-exposed WebAssembly objects to be more like other such objects in V8. By introducing a new instance type for each of the JS-exposed types, we get more robust typechecking without using embedder fields (which were previously used when these objects where instance type JS_API_OBJECT). In addition to the new instance types, the subclasses X of JSObject (WasmInstanceObject, WasmMemoryObject, WasmModuleObject, WasmTableObject) now have appropriate Is##X() methods on Object and are now robust.

This CL changes for floats what https://chromium-review.googlesource.com/c/558964/ changed for doubles. Original message: On x86, signalling NaNs get converted to quiet NaNs when they get push on the stack and popped again. This happens in the code generation for arm, specifically for the vmov instruction with the immediate parameter. This CL replaces the vmov function in assembler-arm to take the immediate as a uint64_t instead of a double, to guarantee that the bit pattern does not change even if the parameter is a signalling NaN. New in this CL: Although src/double.h existed already, src/float.h did not exist yet. I created the file in this CL, and moved the classes Float32 and Float64 there, which already existed in src/deoptimizer.h.

The PrepareCallCFunction methods would take a scratch register as arguments when they can simply use ip. The reason to do this, apart from simplifying the code, is that TurboFan's code generator uses r9 as a scratch for this when it could just as well use ip.

The ')'-in-parameter checking is not necessary for CompileFunctionInContext. The arguments array is expected to be an array of identifiers, not an array of arbitrary strings that get concatenated. Furthermore, there's no reason to have the .toString() representation look like it came from CreateDynamicFunction(), and in fact inserting line breaks makes it more complicated to map line and column numbers correctly. Overall, the --harmony-function-tostring behavior only makes CompileFunctionInContext worse, so this CL removes it.

Tsan figured out that I called compilation_units_.empty() outside a lock. Original message: This CL adds a new function {InitializeCompilationUnit} to initialize a single compilation unit and not just all compilation units at once. This is necessary for streaming compilation eventually. This also required some refactoring on how the working queue for compilation units works. Previously the synchronization was done with an atomic counter, now it is done with a lock. Note that the code to finish compilation of a module still only works if the working queue gets only empty when all work is done. I plan to change this in a different CL. Since the code would not be tested without streaming compilation, I added an experimental flag and a test to test the new code.

In the original CL I moved an error check backwards, unfortunately behind a vector lookup which should not happen when there is an error. Now I also move the vector lookup backwards. Original message: We stored the size of a function body before we check that these values are valid.
