63f9ee1645 [asm.js] Fix Math.min/max signatures to take signed.
This fixes the signature of "Math.min" and "Math.max" for integer values
from "(int, int...) -> signed" to "(signed, signed..) -> signed" which
properly distinguishes signed from unsigned values now. This is in sync
with the spec errata (and ECMAScript semantics).

8d38c15e04 [cleanup] Fix (D)CHECK macros in src/{debug,inspector}
Use the (D)CHECK_{EQ,NE,GT,...} macros instead of (D)CHECK with an
embedded comparison. This gives better error messages and also does the
right comparison for signed/unsigned mismatches.

This will allow us to reenable the readability/check cpplint check.

62960a0340 [parser] Skipping inner funcs: fix async arrow funcs.
Track whether the async arrow func parameter list was simple or not; the
information is already there, we just didn't pipe it through correctly. It's
needed by PreParser so that it can create the correct Scope structure.

Implementation notes:

- I could've used async_classifier for transmitting the "is_simple" bit, but I
  made it explicit (it would be unnecessary to use ExpressionClassifier for
  this, as we're not classifying any expressions) instead.

- I'm also moving work (setting parameter_list.is_simple) from Parser to
  ParserBase, and adding a DCHECK in Parser to assert that the work was indeed
  already done.

7816413f29 [turbofan] Constant-fold keyed loads of sealed properties.
We can constant-fold JSLoadProperty(o, i) when o is a known object (i.e.
TurboFan's context specialization provides a known non-null/-undefined
constant value for it), i is a known array index and o["i"] is an
element on the receiver, that is non-configurable and non-writable (i.e.
o was frozen using Object.freeze earlier, or o is a String object).

This significantly reduces execution time of the tagged templates
micro-benchmarks (ES6 and Babel transpiled), when combined with the
CL https://chromium-review.googlesource.com/c/v8/v8/+/677462, it goes
from

  templateStringTagES5: 4552 ms.
  templateStringTagES6: 14185 ms.
  templateStringTagBabel: 7626 ms.

to

  templateStringTagES5: 4550 ms.
  templateStringTagES6: 616 ms.
  templateStringTagBabel: 589 ms.

so overall a solid 23x improvement on the ES6 benchmark. This is
representative of the six-speed-templatestringtag-es6 benchmark.

79ac69b83c [es2015] Introduce dedicated GetTemplateObject bytecode.
Tagged templates were previously desugared during parsing using some
combination of runtime support written in JavaScript and C++, which
prevented some optimizations from happening, namely the constant folding
of the template object in TurboFan optimized code. This CL adds a new
bytecode GetTemplateObject (with a corresponding GetTemplateObject AST
node), which represents the abstract operation in the ES6 specification
and allows TurboFan to simply constant-fold template objects at compile
time (which is explicitly supported by the specification).

This also pays down some technical debt by removing the template.js
runtime support and therefore should reduce the size of the native
context (snapshot) a bit.

With this change in-place the ES6 version microbenchmark in the
referenced tracking bug is now faster than the transpiled Babel
code, it goes from

  templateStringTagES5: 4552 ms.
  templateStringTagES6: 14185 ms.
  templateStringTagBabel: 7626 ms.

to

  templateStringTagES5: 4515 ms.
  templateStringTagES6: 7491 ms.
  templateStringTagBabel: 7639 ms.

which corresponds to a solid 45% reduction in execution time. With some
further optimizations the ES6 version should be able to outperform the
ES5 version. This micro-benchmark should be fairly representative of the
six-speed-templatestringtag-es6 benchmark, and as such that benchmark
should also improve by around 50%.

9693835aeb [wasm] [decoder] Minor interface change
The baseline compiler needs to know the depth in order to access the
parent block. This is a small CL, but anything that can land before the
big baseline CL reduced the complexity of the latter.

3a06391166 [base] Allow comparing enums in (D)CHECKs
In the current implementation, compilation would fail because
operator<< is not defined for enum classes. For others, the compiler
finds more than one operator<<, so it fails because it's ambiguous.

This CL fixes this by printing the integer value for enums, uses the
operator<< for all values that support it, and prints "<unprintable>"
otherwise.

Also, lots of unit tests.

008d7b2ad2 [wasm] Remove redundant validation
And add some tests for (seemingly) previously uncovered cases.
The additional check for unreachable code is not needed any more, since
polymorphic stack values get assigned a specific type on their first
use or validation anyway. Hence the first entry in the br_table will
assign specific types to all polymorphic stack values, and type checking
will fail if later entries do not match.

6389b7e6b6 [unicode] Return (the correct) errors for overlong / surrogate sequences.
This fix is two-fold:

1) Incremental UTF-8 decoding: Unify incorrect UTF-8 handling between V8 and
Blink.

Incremental UTF-8 decoding used to allow some overlong sequences / invalid code
points which Blink treated as errors. This caused the decoder and the Blink
UTF-8 decoder to produce a different number of bytes, resulting in random
failures when scripts were streamed (especially, this was detected by the
skipping inner functions feature which adds CHECKs against expected function
positions).

2) Non-incremental UTF-8 decoding: return the correct amount of invalid characters.

According to the encoding spec ( https://encoding.spec.whatwg.org/#utf-8-decoder
), the first byte of an overlong sequence / invalid code point generates an
invalid character, and the rest of the bytes are not processed (i.e., pushed
back to the byte stream). When they're handled, they will look like lonely
continuation bytes, and will generate an invalid character each.

As a result, an overlong 4-byte sequence should generate 4 invalid characters
(not 1).

This is a potentially breaking change, since the (non-incremental) UTF-8
decoding is exposed via the API (String::NewFromUtf8). The behavioral difference
happens when the client is passing in invalid UTF-8 (containing overlong /
surrogate sequences).

However, afaict, this doesn't change the semantics of any JavaScript program:
according to the ECMAScript spec, the program is a sequence of Unicode code
points, and there's no way to invoke the UTF-8 decoding functionalities from
inside JavaScript. Though, this changes the behavior of d8 when decoding source
files which are invalid UTF-8.

This doesn't change anything related to URI decoding (it already throws
exceptions for overlong sequences / invalid code points).

255bf2d65a v8: Fix most -Wunreachable-code warnings.
Do this by deleting code after calls to V8_Fatal() (either through
UNREACHABLE() or FATAL()). Comments suggest that the returns there
were needed to make a compiler happy, but all compilers seem to be
happy with this change too. My guess is that either
https://codereview.chromium.org/1393023003 which marked V8_Fatal()
as noreturn, or https://chromium-review.googlesource.com/#/c/544845/
which switched to the C++11 spelling of noreturn, fixed the warnings
that the explicit code after V8_Fatal() was supposed to silence.

There's one more warning in src/compiler/machine-graph-verifier.cc,
but fixing that changes behavior.  I asked about that one in
https://codereview.chromium.org/2573573004/#msg27 instead.
