[nojit] Add a kCallBuiltinPointer call kind · f323a5f4

Jakob Gruber authored Dec 17, 2018

Currently, Torque's builtin pointers store a Code target underneath and
callsites generate a kArchCallCodeObject opcode. When embedded builtins
are enabled, the call thus first calls the on-heap trampoline, which
finally jumps to the target off-heap builtin code.

This will no longer be possible in jitless mode, since on-heap code must
not be executable.

As a step towards changing the way builtin pointers are called
(function pointers will hold the builtin index as a Smi, and callsites
look up the off-heap target address and jump there), this CL adds a
dedicated opcode for builtin pointer calls to the compiler pipeline.

The calling mechanism itself is unchanged, changes there will happen
in a follow-up.

Drive-by: rename 'FunctionPointer' in torque/ to 'BuiltinPointer'.

[js weak refs] Migrate the WeakRef parts into the new API · fef6f8ed

New API is here: https://github.com/tc39/proposal-weakrefs/issues/55

The WeakCell parts stay in the old API, resulting in temporary code duplication
in some parts. Those parts will go away once the WeakCell-related parts are
migrated to the new API (but the spec needs some work first).

[esnext] ship Object.fromEntries · dde25872

Caitlin Potter authored Dec 15, 2018

Enable --harmony-object-from-entries by default.

Object.fromEntries is a new standard library method, whose proposal
(https://tc39.github.io/proposal-object-from-entries/) is currently
at stage 3.

It simply creates a JSObject from an iterable collection of key/value
pairs, such that `Object.fromEntries([ [ "a", "b" ] ]) -> { a: "b" }`

[builtins] Port GetArgumentsFrameAndCount to Torque · a74afec6

Daniel Clifford authored Dec 14, 2018

In the process, add the bint type (which stands for Best-INTeger),
which implements Torque's idea of CSA's ParameterMode. It maps to
a different type on 32-bit (Smi) and 64-bit (intptr). There are
convert operators that are either no-ops or conversions
to-and-from Smi and intptrs on the each platform, depending on
the underlying type for bint. This allows Torque code to git most
of the benefits of ParameterMode without having to explicitly
pass around the mode, since it is almost always OptimalMode anyways.

[esnext] Ship String.p.matchAll/RegExp.p.[@@matchAll] · 76cb4fe6

peterwmwong authored Dec 14, 2018

Enable --harmony-string-matchall by default.

String.prototype.matchAll behaves similarly to
String.prototype.match, but returns a full regexp
result object for each match in a global or sticky
regexp. This offers a simple way to iterate over
matches when access to e.g. capture groups is
needed.

const string = 'a b c';
const regex = /[ac]/g;
for (const match of string.matchAll(regex)) {
  console.log(`${match[0]} at ${match.index}`);
}
// a at 0
// c at 4

More information can be found here:
https://github.com/tc39/proposal-string-matchall

Drive-by: Update debug evaluate side effect
expectations to handle String.p.matchAll and
RegExp.p[@@matchAll]

For mips{,64}/macro-assembler-mips{,64}.cc, remove extra references to masm.
