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.

For M65 I added a fast-path for String.p.charCodeAt, which behaves incorrectly for wide characters. This patch disables the incorrect fast-path. This is likely no performance regression against M64, as M64 did not have a fast path for String.p.charCodeAt.

This is somewhat of a revival of what used to be UnseededNumberDictionary. The difference to NumberDictionary is that each entry only has two fields (no field for property details) and there is no header field for a bitfield. The reason for this change is memory regression introduced when we removed UnseededNumberDictionary (6e1c57ea). We now use SimpleNumberDictionary for - slow template instantiation cache - code stubs table - value serializer map - stack frame cache - type profile source positions R=ishell@chromium.org, ulan@chromium.org Bug: chromium:783695 Change-Id: I3cd32e485060bb379fb2279eeefbbbded7455f0e Reviewed-on: https://chromium-review.googlesource.com/885811Reviewed-by:

When moving arguments for calls into the right registers and stack slots, we were sometimes overwriting stack slots which would still be used later to load arguments from. This is because we popped the (wasm) value stack before executing the register moves, hence the stack transfer would think the values are not being used any more and reuse the stack slots. With this CL, we only pop the arguments from the stack after executing the stack transfer.

This adds a new operator JSCreatePromise, which currently allocates a native JSPromise instance and initializes it to pending state. In addition to that we introduce a new PromiseHookProtector, which get's invalidated the first time someone enables the debugger or installs a PromiseHook (via async_hooks for example). As long as the protector is intact we lower AsyncFunctionPromiseCreate to JSCreatePromise and AsyncFunctionPromiseRelease to a no-op in optimized code. This yields a speedup of roughly 33% on the benchmark mentioned in the bug.
