Optimize Object.seal and Object.preventExtensions
...
They both now run fast (due to utilizing transitions instead of always
creating new maps) and sealed or non-extensible objects can stay in
fast mode after transitioning.
This almost entirely reuses the code for transitioning objects
frozen by Object.freeze(), with the added benefit of freeing
up a bit on the map (we no longer keep track of frozen-ness,
as that bit wasn't used for anything interesting).

Make JSTests ready for Android measurements.
...
This adds a common perf configuration for JSTests including
Classes, Collections, Iterators and Strings. This allows
the android test runner to handle subdirectories correctly
and to share the base.js resource in the parent directory.
The new json config has added resources configs for the
Android runner.
The perf runner's relative paths on the device are fixed as
well. Resources are only pushed on the configuration node
where they are specified. They are pushed to a dir on the
device that follows the same directory structure as on the
host. The binary is executed in the benchmark folder on the
device like on the host to allow relative path file
loading.

Make test-parsing faster: don't run parsing tests with all experimental flag combinations.
...
Instead, make it possible for indifidual tests to pass "always true flags" which
are not part of the varying flag set.
The downside is that if an experimental flag changes parsing of some of the
unrelated code snippets, it's noticed later (only after the flag is turned on by
default). But this is a reasonable trade off for faster tests.
Additional fix: Some tests (ErrorsFutureStrictReservedWords) were using
always_flags incorrectly (running two different tests with different
always_flags basically iterates over every flag combination anyway - most of
them twice).

harmony-scoping: make assignment to 'const' a late error.
...
Per TC39 Nov 2014 decision.
This patch also changes behavior for "legacy const": assignments to sloppy const in strict mode is now also a type error. This fixes v8:2243 and also brings us in compliance with other engines re assignment to function names (see updated webkit test), but might have bigger implications.
That change can easily be reverted by changing Variable::IsSignallingAssignmentToConst.

Disable ParserSync test for now, it takes waaaaay too long.
...
Running this in x64.release mode on a powerful HP620 takes 4 seconds,
this is at least 2 orders of magnitude too slow and leads to tons of
false positives on our build bots due to timeouts. As it is, the
cost-benefit ratio is far too low.
The whole approach needs to be changed: Instead of trying to exhaust
some search space in unit tests, this should be turned into a fuzzing
test where only a small but random number of things are tested. The
exhaustive approach can be done separately, but definitely not in the
unit tests.

cctest/test-threads/ThreadJoinSelf is suppressed for Android, but the
test has since been moved to unittests/Thread.SelfJoin. Move the
suppression to unittests.status.
unittests/ThreadLocalStorageTest.DoTest fails on older Android devices
as it assumes the availability of more TLS slots than many devices
implement. Test a smaller number of slots (32) on Android. Remove old
suppression of test-platform-tls/FastTLS (which no longer exists).
cctest/test-mark-compact/RegressJoinThreadsOnIsolateDeinit can't deal
with shared mappings. Check for 's' instead of '-'.

Conditional flags for tests - set JS stack size for simulators.
...
There are separated JS and C stacks on simulators so for some stack
extensive tests (like mozilla/js1_5/extensions/regress-355497) might
cause a C stack overflow and that overflow is not caught by V8. It is
not an issue on real HW. Increasing the C stack also solves the problem
but we have already FLAG_sim_stack_size flag to control the JS stack
size.
This patch makes it possible to add flags to tests conditionally in
.status files.

ScriptScope reflects ScriptContextTable.

[turbofan] Remove int32 narrowing during typed lowering.
...
With Int32Add we lose the int/uint distinction, so later, in simplified lowering we can make a wrong decision. E.g., see the attached test case, where we lower NumberAdd -> Int32Add because inputs are Uint32, but during simplified lowering we change the inputs to Int32, so we get a wrong result.
Simplified lowering will lower the NumberAdd operations anyway, so we should lose performance.

Classes: Add support for arguments in default constructor
...
This is currently done by generating a default constructor that looks
like this:
constructor() {
%DefaultConstructorSuperCall();
}
The a runtime function implements the logic which is pretty similar to
Runtime_Apply except that it uses the [[Prototype]] of the current
function.
This is the second try. The first failed because the test was using a
array that was too large for Function.prototype.apply.

Fix bugs in simplified lowering relating to int32/uint32 signs.
...
Lowering of NumberToUint32 and NumberToInt32 was not correctly accounting for the sign of the input and the sign of the output, emitting the wrong representation changes.
Along the way, I've found cases where MachineOperatorBuilder would break if fed a machine type for loads or stores that was not cached, requiring MachineOperatorBuilder to take zone to allocate operators for these cases.

harmony_scoping: Implement lexical bindings at top level
...
This implements correct semantics for "extensible" top level lexical scope.
The entire lexical scope is represented at runtime by GlobalContextTable, reachable from native context and accumulating global contexts from every script loaded into the context.
When the new script starts executing, it does the following validation:
- checks the GlobalContextTable and global object (non-configurable own) properties against the set of declarations it introduces and reports potential conflicts.
- invalidates the conflicting PropertyCells on global object, so that any code depending on them will miss/deopt causing any contextual lookups to be reexecuted under the new bindings
- adds the lexical bindings it introduces to the GlobalContextTable
Loads and stores for contextual lookups are modified so that they check the GlobalContextTable before looking up properties on global object, thus implementing the shadowing of global object properties by lexical declarations.

Scanner: disallow unicode escapes in regexp flags.
...
The spec explicitly forbids them. V8 never handled them properly either, just
the Scanner accepted them (it had code to add them literally to the
LiteralBuffer) and later on, Regexp constructor disallowed them.
According to the spec, unicode escapes in regexp flags should be an early error
("It is a Syntax Error if IdentifierPart contains a Unicode escape sequence.").
Note that Scanner is still more relaxed about regexp flags than the
spec. Especially, it accepts any identifier parts (not just a small set of
letters) and doesn't check for duplicates.

The idea behind of this solution is to use the existing "relocation info" instead of consumption the CodeLinePosition events emitted by the V8 compilers.
...
During generation code and relocation info are generated simultaneously.
When code generation is done you each code object has associated "relocation info".
Relocation information lets V8 to mark interesting places in the generated code: the pointers that might need to be relocated (after garbage collection),
correspondences between the machine program counter and source locations for stack walking.
This patch:
1. Add more source positions info in reloc info to make it suitable for source level mapping.
The amount of data should not be increased dramatically because (1) V8 already marks interesting places in the generated code and
(2) V8 does not write redundant information (it writes a pair (pc_offset, pos) only if pos is changed and skips other).
I measured it on Octane benchmark - for unoptimized code the number of source positions may achieve 2x ('lin_solve' from NavierStokes benchmark).
2. When a sample happens, CPU profiler finds a code object by pc, then use its reloc info to match the sample to a source line.
If a source line is found that hit counter is increased by one for this line.
3. Add a new public V8 API to get the hit source lines by CDT CPU profiler.
Note that it's expected a minor patch in Blink to pack the source level info in JSON to be shown.
4.Add a test that checks how the samples are distributed through source lines.
It tests two cases: (1) relocation info created during code generation and (2) relocation info associated with precompiled function's version.

Make special RPO computation iterative during scheduling.
...
This contains the following changes squashed together:
- Switch BasicBlock::loop_end to be a basic block instead of an RPO.
- Switch ScheduleLate to use dominator depth instead of RPO.
- Switch ScheduleEarly to use dominator depth instead of RPO.
- Push out absolute RPO ordering everywhere else in the scheduler.
- Keep linked list of blocks in RPO order while scheduling.
- Switch from RPO number to depth for dominator calculation.

Clear old backing store of WeakCollection on updates.
...
Not clearing can lead to a crash under following conditions:
1. Backing store of a weak map is allocated in large object space.
2. The backing store is marked incrementaly via the weak map.
3. The weak map is updated and gets a new backing store.
4. The store buffer overflows and marks the chunk of the old backing store as
"scan on scavenge."
5. Mark-compact collection kills some elements of the weak map. Note that the
old backing store survives because it was marked incrementally, but its dead
elements are not cleared.
6. Scavenger iterates over the old backing store, tries to move a dead object
and crashes.

Scanner: remove PushBack calls when we're going to return ILLEGAL.
...
This simplifies escape handling and makes it easier to extend escapes for ES6.
PushBack just before detecting ILLEGAL is unnecessary, since we will abort the
scanning / parsing anyway at that point, and it doesn't matter where the cursor
exactly is. The error messages w/ PushBack are not any better or more correct
than without.
In addition: remove a comment about handling invalid escapes gracefully when we
no longer do. (*)
This CL includes a behavioral change: For input "var r = /foobar/g\urrrr;" we
used to report "unexpected_token: ILLEGAL" for "\u", but now we report
malformed_regexp_flags which is a more correct error message. (Note that the
code for reporting invalid_regexp_flags was dead, and invalid_regexp_flags is
not the right error message.)
Note that the V8 is more relaxed about unicode escapes in regexp flags than ES6
(see
http://people.mozilla.org/~jorendorff/es6-draft.html#sec-regular-expressions )
and this CL doesn't change it. (V8 accepts any \uxxxx, ES6 spec says only a
certain value range is acceptable.)
(*) Code archaeology:
Originally, doing PushBack in ScanHexEscape made sense (see e.g., here
https://codereview.chromium.org/5063003/diff/6001/src/prescanner.h ), since we
wouldn't return ILLEGAL but treat an invalid escape sequence "\uxxxx" as
"uxxxx".
(The repo at that point contains another instance of the same function, from the
initial commit. The logic is the same.)
This behavior was changed in a "renaming" commit
https://codereview.chromium.org/7739020 .

Add performance tests for Map/Set with String and Object keys
...
The big change here is to split out each key type into its own
benchmark suite, since optimizations for different key types
are likely to be disjoint. ForEach tests have also been split
into separate "Iteration" suites, again with the thought that
iteration performance is likely separable from key type.
As part of adding the new tests, rejiggered the existing tests:
- Map.set and Set.add (along with their Weak variants) no longer
include construction costs in their scores
- Moved key logic into the shared common.js

Implement loop variable assignment analysis.
...
This analysis computes the set of variables that are assigned in each loop. This is useful to avoid creating redundant loop phis when building an SSA graph, which just waste memory and require analysis to get rid of.
This CL implements an AST walk for the analysis and plugs the result into the TurboFan graph builder. I left this analysis under a flag for A/B testing and until sufficient unit tests can be developed.

Introduce FeedbackNexus for vector-based ics.
...
A FeedbackNexus is the combination of a feedback vector, a slot(s) in
the vector, along with methods to query and manipulate that information
in a type-correct way.
A CallIC will have a CallICNexus, a LoadIC a LoadICNexus, etc.,
reflecting the fact that different types of ICs configure their data
in unique ways.
This CL limits itself to introducing and using the nexus type only for
CallICs. A follow-up will use them for Load and KeyedLoadICs for the
case when the --vector-ics flag is turned on.
The notion of a Nexus is also embedded at the lowest level of the IC
class. This makes sense because more ICs should become vector-based
in the future.

Limit the number of transitions allowed per hidden class.
...
Each time a transition is added to a hidden class, the whole
transitions array must be copied, which causes poor performance
in some circumstances. This change limits the maximum size of
the transition array, avoiding this behavior in the pathological
case. For example, this improves the performance of the EtchMark
benchmark by nearly 60%.

Narrow cases where Sparse/Smart versions of Array methods are used
...
Added a new %HasComplexElements runtime function (meaning elements that are
non-writable, non-configurable, or have getters and setters) and use it
in UseSparseVariant to filter out cases where the sparse optimizations
can cause V8 to fall out of spec compliance.
Renamed SmartMove/SmartSlice to SparseMove/SparseSlice and guarded them
with the new and improved UseSparseVariant.
These two changes combine let us pass nearly every test in bug-2615.js,
as well as fixing reverse and join on sparse arrays.
Note that there are various test changes in this patch that correct existing
tests to match the correct-by-spec behavior.
This patch depends on https://codereview.chromium.org/666883009 , which
better-aligns the behavior of SmartMove with SimpleMove.

Change SmartMove no-op behavior to match SimpleMove (and ES6 spec)
...
The previous behavior, which caused Array.prototype.unshift() (with no args)
to have side-effects, no longer matches the spec (ES6 changed the no-arg behavior
in April 2014). The new SmartMove behavior is also compatible with current
versions of Firefox.
This is a baby step towards getting rid of SmartMove; it isolates the test
change in this patch, instead of lumping it in confusingly with all the
other test updates necessary for moving away from SmartMove.

This is based on Georg's work on typing arithmetic operations (https://codereview.chromium.org/658743002/ ).
Instead of weakening to bitset types, we weaken to the closest 2^n
limit if we see that we are re-typing a node with a range type (which
means that the node can be part of a cycle, so we might need
to speed up the fixpoint there).

This speeds up both the case from the bug (using Object.create) but also
takes care ofthe "{ __proto__: obj }" syntax, which was previously (and
erroneously) being treated the same as setting the prototype dynamically
from script using the __proto__ setter or Object.setPrototypeOf.

Fix {get,set}ter-on-elements tests to run through all creation functions
...
setter-on-elements had the wrong length hardcoded in a for loop over the
creation functions (getter-on-elements had the right length, but seemed
worth future-proofing).

Add Terminate operator.
...
Terminate is need for non-terminating loops (NTLs) that can appear after optimizing control flow. It gathers the control and effect(s) from a NTL and connects them to end so that they are not dead-code removed.
