      [wasm-simd][arm64] Use unique register for shifts · 1485de17
      Ng Zhi An authored 
      The src register needs to be different from the temporary Simd128
register since in the codegen we modify tmp before using tmp and src.

      Reland "[regexp] Rewrite error handling" · 560f2d8b
      Iain Ireland authored 
      This is a reland of e80ca24c

Original change's description:
> [regexp] Rewrite error handling
>
> This patch modifies irregexp's error handling. Instead of representing
> errors as C strings, they are represented as an enumeration value
> (RegExpError), and only converted to strings when throwing the error
> object in regexp.cc. This makes it significantly easier to integrate
> into SpiderMonkey. A few notes:
>
> 1. Depending on whether the stack overflows during parsing or
>    analysis, the stack overflow message can vary ("Stack overflow" or
>    "Maximum call stack size exceeded"). I kept that behaviour in this
>    patch, under the assumption that stack overflow messages are
>    (sadly) the sorts of things that real world code ends up depending
>    on.
>
> 2. Depending on the point in code where the error was identified,
>    invalid unicode escapes could be reported as "Invalid Unicode
>    escape", "Invalid unicode escape", or "Invalid Unicode escape
>    sequence". I fervently hope that nobody depends on the specific
>    wording of a syntax error, so I standardized on the first one. (It
>    was both the most common, and the most consistent with other
>    "Invalid X escape" messages.)
>
> 3. In addition to changing the representation, this patch also adds an
>    error_pos field to RegExpParser and RegExpCompileData, which stores
>    the position at which an error occurred. This is used by
>    SpiderMonkey to provide more helpful messages about where a syntax
>    error occurred in large regular expressions.
>
> 4. This model is closer to V8's existing MessageTemplate
>    infrastructure. I considered trying to integrate it more closely
>    with MessageTemplate, but since one of our stated goals for this
>    project was to make it easier to use irregexp outside of V8, I
>    decided to hold off.

      [wasm] Introduce a TableCopy builtin · 1e1d4d82
      Andreas Haas authored 
      This CL introduces a CSA builtin for the TableCopy instruction. This
builtin allows to generate smaller code for both TurboFan and Liftoff,
and easier code generation from Liftoff.

The smaller code size comes from:
* Parameters are passed through registers, not the stack.
* Lower number of parameters: the call target, number of parameters, and
context are not passed as parameters.
* No int to smi conversion in generated code.
