Reduce register pressure (and therefore spills) across the loop iterating over the LoadIC polymorphic feedback array by starting at length - 1 and iterating down to 0. Might give a tiny recency boost too. Change-Id: I1295a8136212c339b9d3974e2d49b3ecfe1ce543 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1687545Reviewed-by:

Use the position of the next parameter to be declared as the end of the initializer for default parameters, so that hole checks can be elided for initializers using previous parameters in arrow functions. This fixes a source of bytecode mismatches when collecting source positions lazily.

This CL moves the code responsible for serializing a stack trace frame into a string, out of messages.cc and into stack-frame-info.cc. Instead of symbolizing the stack trace frame while serializing, the code is changed to work on top of StackTraceFrame and StackFrameInfo objects. The result is that the serialization code no longer cares when a stack trace frame is symbolized. Symbolization could happen eagerly during capturing, or lazily the first time any of StackFrameInfo fields are accessed. Drive-by: Existing users of StackFrameBase::ToString are adapted to the new SerializeStackTraceFrame API. This includes Isolate::PrintCurrentStackTrace, which is changed to re-use the existing capturing and serializing mechanism.

Andreas Haas authored
This is the combined second and third step of refactoring indirect function calls through tables with index > 0 to work without runtime calls. The first CL introduces the WasmIndirectFunctionTable heap object. For a table of type anyfunc within a WebAssembly instance, WasmIndirectFunctionTable stores the size, the signature id's, the call targets, and the reference parameters for that table. I used the names that are already used for the matching fields of the WasmInstanceObject. The second CL expands the IndirectFunctionTableEntry to work also on WasmIndirectFunctionTable objects. All changes to a function table go through this class. The third CL introduces uses of the WasmIndirectFunctionTable. In this CL I change the code generation in TurboFan to replace runime calls with direct accesses to the new WasmIndirectFunctionTable. Additionally I extended the initialization of WasmIndirectFunctionTable, and also implement Table.grow.

Georg Schmid authored
TypeNarrowing and TypedOptimization can successively narrow range types of loop variables. In the presence of new, precise information on such loop variables, e.g. due to load elimination, many such narrowing steps are necessary, however, leading to very slow convergence of optimizations and an explosion in memory consumption. Until we have a sound way of speeding this process up, we disable TypedOptimization on loop-related Phi nodes.

The test case SimdF32x4ExtractWithI32x4 was still passing when the codegen for F32x4Extract was entirely commented out. This change adds a new test cases that specifically exercises F32x4ExtractLane. It copies what is done in SimdI32x4SplatFromExtract, which involves moving the splatted and extracted values around locals, to ensure we move the values around registers and not unintentionally reuse registers that we splatted to, without actually extracting anything. Note that the existing SimdF32x4ExtractWithI32x4 is kept because it is used to test scalar lowering passes.

Various TurboFan operators and builtins currently conflate the concept of a Unicode code point with that of its UTF-32 and UTF-16 encoding. UTF-16 is only used as an internal optimization, and should not be exposed. This CL separates affected operators and clarifies the naming of various internals. Prior to this CL, StringCodePointAt operator's typing rule was unsound, since it was not strictly limited to returning values in the range of Unicode code points.
