yurys@chromium.org [Wed, 10 Apr 2013 09:47:44 +0000 (09:47 +0000)]
Add sanity test for CPU profiler

The new test checks full CPU profiling cycle: using public
V8 API it starts profiling, executes a script, stops profiling
and analyzes collected profile to check that its top-down
tree has expected strutcture. The script that is being profiled
is guaranteed to run > 200ms to make sure enough samples
are collected.

To avoid possible flakiness due to non-deterministic time required
to start new thread on varios OSs when Sampler and ProfilerEventsProcessor
threads are being started the main thread is blocked until the threads
are running.

Also I removed the heuristic in profile-generator.cc where we try
to figure out if the value on top of the sampled stack is return address
of some frameless stub invocation. The code periodically gives false positive
with the new test ending up in an extra node in the collected cpu profile.
After discussion with jkummerow@ we concluded that the logic is too fragile
and that we can address frameless stub invocations in a more reliable way
later should they have a noticeable effect on cpu profiling.

11 years agoRefactor parser mode configuration for correctness
mstarzinger@chromium.org [Fri, 5 Apr 2013 13:01:06 +0000 (13:01 +0000)]
Refactor parser mode configuration for correctness

This patch refactors the parser and preparser interface to be more
readable and type-safe.  It has no behavior changes.

Previously, parsers and preparsers were configured via bitfield called
parser_flags in the Parser constructor, and flags in
PreParser::PreParseProgram, ParserApi::Parse, and ParserApi::PreParse.
This was error-prone in practice: six call sites passed incorrectly
typed values to this interface (a boolean FLAG value, a boolean false
and a boolean true value).  None of these errors were caught by the
compiler because it's just an "int".

The parser flags interface was also awkward because it encoded a
language mode, but the language mode was only used to turn on harmony
scoping or not -- it wasn't used to actually set the parser's language
mode.

Fundamentally these errors came in because of the desire for a
procedural parser interface, in ParserApi.  Because we need to be able
to configure the parser in various ways, the flags argument got added;
but no one understood how to use the flags properly.  Also they were
only used by constructors: callers packed bits, and the constructors
unpacked them into booleans on the parser or preparser.

The solution is to allow parser construction, configuration, and
invocation to be separated.  This patch does that.

It passes the existing tests.

mstarzinger@chromium.org [Tue, 2 Apr 2013 17:34:59 +0000 (17:34 +0000)]
Add parser support for generators.

This patchset begins by adding support for "yield", which is unlike other tokens
in JS. In a generator, whether strict or classic, it is a syntactic keyword.
In classic mode it is an identifier. In strict mode it is reserved.

This patch adds YIELD as a token to the scanner, and adapts the preparser and
parser appropriately. It also parses "function*", indicating that a function is
actually a generator, for both eagerly and lazily parsed functions.

Currently "yield" just compiles as "return".
