With the new builtin optimization guard we can just speculatively assume that the index passed to String#charAt and String#charCodeAt (in optimized code) is going to be within the valid range for the receiver. This is what Crankshaft used to do, and it avoids Smi checks on the result for String#charCodeAt, since it can no longer return NaN. This gives rise to further optimizations of these builtins (i.e. to completely avoid the tagging of char codes), and by itself already improves the regression test originally reported from 650ms to 610ms.

We need to maintain TypeGuard nodes until the EffectControlLinearizer, because they can protect partial operations from floating above a check. In the linked bug, it was a DeadValue node that got scheduled too early. In LoadElimination and EscapeAnalysis, the inserted TypeGuard nodes might depend on map checks on the effect chain. Thus TypeGuard has to be an effect chain node too. Bug: chromium:800929 Change-Id: Icdcff96a2273d96b7f8cd6f85511ad62c1cb129a Reviewed-on: https://chromium-review.googlesource.com/860405Reviewed-by:

This is the first in a series of CLs that will separate the JS API from the implementation of WebAssembly by bottlenecking interactions through the WasmEngine. In the long run, the JS API and much of V8 should rely only on the WasmEngine interface, which will represent the "public interface" for embedding WebAssembly. Next: hide compilation-related methods behind WasmEngine.

This will switch on various testing features in sanitizer builds and for correctness fuzzer builds. Currently we group enabling the slow-path runtime flag and allocation timeout for atomic gc stress, but more features could be added in the future. This will enable gc fuzzer, clusterfuzz and correctness fuzzer to use both slow-path and atomic gc stress in release sanitizer builds.

For memory tracing, output a 'T' for Turbofan code and an 'L' for Liftoff code. To do this, the WasmCodeWrapper now has some dispatch functions which work for both on-the-heap and off-the-heap code. We can probably refactor more code by having this mechanism. Since the output of --wasm-trace-memory differs now between Turbofan and Liftoff, the message test is split in two.

This adds support for tracing memory operations in code compiled with Liftoff. This is the first runtime call we emit from Liftoff code, so part of this code can be reused for other runtime calls.

Assembler::PopAndReturn expects an Integral type so convert argc from a SMI if necessary. On 64-bit architectures, convert 64-bit immediate pop values into 32-bit values. This is safe since the conversion checks that nothing was truncated. Also change CodeStubArguments unit tests to use PopAndReturn rather than Return.

The method {SpillAllRegisters} should really just spill registers, and not also constants. Also, since more code is inlined into that method now, we can optimize it to update register use counters only once in the end, since no used register should be left after executing this method.

This is the implementation of crrev.com/c/866721 for ia32. Drive-by change: Clean up the slot index calculation. At the moment the slot index is encoded in the opcode. This, however, sets an upper limit the slot index which is lower than what we want to have (i.e. < 512). With this change we pass the slot index as an immediate operand, which does not impose limits on the value it contains.
