009fe698ee The file snapshot_blob_host.bin was supposed to be generated when building the host toolset. However, the file snapshot_blob.bin was being generated instead, under every set of conditions.
Because of this, every time we build the host toolset, snapshot_blob_host.bin is not found. This causes the target (v8_external_snapshot) that generates such file to be run. This target generates snapshot_blob.bin instead of snapshot_blob_host.bin. This in turn causes all the targets that depend on snapshot_blob.bin to run again.

After this, we still don't have snapshot_blob_host.bin. So the next time we build, the whole process described above happens again.

90a7f07489 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.

Symbol.toStringTag is exposed publicly.

e4c6f9488e Implement graph trimming in ControlReducer.
Trimming the graph consists of breaking links from nodes that are not reachable from end to nodes that are reachable from end. Such dead nodes show up in the use lists of the live nodes and though mostly harmless, just clutter up the graph. They also can limit instruction selection opportunities, so it is good to get rid of them.

This CL is one half of the ControlReducer functionality, the other half
being branch folding.

0dd69ec439 Allow identifier code points from supplementary multilingual planes.
ES5.1 section 6 ("Source Text"):
"Throughout the rest of this document, the phrase “code unit” and the
word “character” will be used to refer to a 16-bit unsigned value
used to represent a single 16-bit unit of text."

This changed in ES6 draft section 10.1 ("Source Text"):
"The ECMAScript code is expressed using Unicode, version 5.1 or later.
ECMAScript source text is a sequence of code points. All Unicode code
point values from U+0000 to U+10FFFF, including surrogate code points,
may occur in source text where permitted by the ECMAScript grammars."

This patch is to reflect this spec change.

These types can now express uint8, int8, uint16, and int16, i.e. signed and unsigned smallish integers. Note that currently only uint8 and uint16 are implemented in the TF backends.

The new pattern is that we first get the map of the root of the
prototype chain using Object::GetMapRoot() and then walk up the
prototype chain using Map::prototype().

a0f6878a06 Add mips64 port.
Summary:

- Changes in common code are mainly boilerplate changes,
gyp and test status files updates.

- On mips64 simulator all tests pass from all test units.

- Current issues: mjsunit JS debugger tests fail randomly on HW in release mode.
Corresponding tests are skipped on HW.

- Skipped tests on mips64: test-heap/ReleaseOverReservedPages, mjsunit/debug-*

Also remove the "use default platform" compile flag. Instead, the embedder
has to provide the platform.

Change all binaries to use the default platfrom from libplatform.

Unless --job-based-sweeping is passed, nothing uses the platform yet, so
nothing will break for embedders (yet).

1f338fa2e8 Linux perf tool support update + refactoring.
This adds timestamps to allow profiling with code space reuse. Also a couple of updates to reflect the changes in the JIT perf interface + a move of the perf-related stuff into separate files.

Unfortunately, the change only works with the latest patch  to the perf tool from a Linux perf tool contributor (Stephane Eranian).

7b7bb25a24 Support external startup data in V8.
[Re-retry of r21696 and r21739]

If the embedder chooses, the 'natives' (library sources) and the
precompiled startup blob can be written to files during the build
process and handed over to V8 at startup. The main purpose would be
to reduce the size of the compiled binary for space constrained
platforms.

The build-time option is off by default. Nothing should change if
it's not enabled.

7f429e62c3 [Arm]: Simplify compile-time Arm feature detection.
Simplify the compile time feature detection on Arm:
 - Define CAN_USE_XXX definitions unconditionally for all target/host
   toolchain combinations
 - Rename arm_test / ARM_TEST to arm_test_noprob / ARM_TEST_NO_FEATURE_PROBE
 - Don't set ARM_TEST_NO_FEATURE_PROBE implicitly on the simulator to make
   make simulator / native more consistent
 - Unify CpuFeatures::PrintTarget for simulator and native builds
 - Remove unecessary CAN_USE_VFP_INSTRUCTIONS definition for android (this is
   the default for arm_fpu=default)
 - Add a CpuFeatures::Probe() before calling CpuFeatures::PrintFeatures() in PrintHelp
    to ensure we have probed features before printing them.
