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.

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%.

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.

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.

Marja Hölttä authored
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).

There is no support to emulate atomic WASM operations on big-endian platforms, since this would require bit swapping as a part of atomic operations. Therefore, cctest/test-run-wasm-atomics/* will be skipped.

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.
