      [wasm-simd][liftoff][ia32][x64] Implement floating-point roundings · 7f654693
      Ng Zhi An authored 
      Implement f32x4 and f64x2 nearest, trunc, ceil, and floor for ia32 and
x64. arm and arm64 will follow in a future patch, now they just bail out
into a runtime call.

      [wasm][liftoff] Delete unused parameter in StoreTaggedPointer · 8e7d2844
      Andreas Haas authored 
      The {offset_reg} parameter was introduced so that the signature of
StoreTaggedPointer is the same as for Store, and also to prepare for
potential later uses. However, handling the parameter would introduce
additional complexity, and chances are low that it will ever be used.
That's why this CL just removes it.

      Ng Zhi An authored 
      dst might not be the same as src0 (since we don't define them to be
equals in the instruction-selector if AVX is enabled), so the minps
and maxps comparisons were incorrect.

I found this while trying to run some spec tests, so not adding any
unittest, eventually when the spec tests are enabled, this will be
covered.

      [cpu-profiler] Ensure sampled thread has Isolate lock under Windows · 76217f57
      Alex Kodat authored 
      While the sampler checked if the sampled thread had the Isolate locked
(if locks are being used) under Linux, the check was not done under
Windows (or Fuchsia) which meant that in a multi-threading application
under Windows, thread locking was not checked making it prone to seg
faults and the like as the profiler would be using isolate->js_entry_sp
to determine the stack to walk but isolate->js_entry_sp is the stack
pointer for the thread that currently has the Isolate lock so, if the
sampled thread does not have the lock, the sampler woud be iterating
over the wrong stack, one that might actually be actively changing on
another thread. The fix was to move the lock check into CpuSampler
and Ticker (--prof) so all OSes would do the correct check.

The basic concept is that on all operating systems a CpuProfiler, and
so its corresponding CpuCampler, the profiler is tied to a thread.
This is not based on first principles or anything, it's simply the
way it works in V8, though it is a useful conceit as it makes
visualization and interpretation of profile data much easier.

To collect a sample on a thread associated with a profiler the thread
must be stopped for obvious reasons -- walking the stack of a running
thread is a formula for disaster. The mechanism for stopping a thread
is OS-specific and is done in sample.cc. There are currently three
basic approaches, one for Linux/Unix variants, one for Windows and one
for Fuchsia. The approaches vary as to which thread actually collects
the sample -- under Linux the sample is actually collected on the
(interrupted) sampled thread whereas under Fuchsia/Windows it's on
a separate thread.

However, in a multi-threaded environment (where Locker is used), it's
not sufficient for the sampled thread to be stopped. Because the stack
walk involves looking in the Isolate heap, no other thread can be
messing with the heap while the sample is collected. The only ways to
ensure this would be to either stop all threads whenever collecting a
sample, or to ensure that the thread being sampled holds the Isolate
lock so prevents other threads from messing with the heap. While there
might be something to be said for the "stop all threads" approach, the
current approach in V8 is to only stop the sampled thread so, if in a
multi-threaded environment, the profiler must check if the thread being
sampled holds the Isolate lock.

Since this check must be done, independent of which thread the sample
is being collected on (since it varies from OS to OS), the approach is
to save the thread id of the thread to be profiled/sampled when the
CpuSampler is instantiated (on all OSes it is instantiated on the
sampled thread) and then check that thread id against the Isolate lock
holder thread id before collecting a sample. If it matches, we know
sample.cc has stop the sampled thread, one way or another, and we know
that no other thread can mess with the heap (since the stopped thread
holds the Isolate lock) so it's safe to walk the stack and collect data
from the heap so the sample can be taken. It it doesn't match, we can't
safely collect the sample so we don't.

      [test] Print less in verbose mode · d8d6110b
      Michael Achenbach authored 
      I/O is quite expensive on the bots. This cuts down a bit of it by
printing slightly fewer characters per test in verbose mode.

This leads to an overall speed improvement of ~20% for large test
suites, e.g. Test262 output-collection time goes from ~2m30 to ~2m.

The averages to a 5-10% overall speed improvement for slow tryjobs.

      Reland "[compiler] Replace JSDataView with direct reads" · 785d701f
      Santiago Aboy Solanes authored 
      This is a reland of b5f37051

Got reverted since it was breaking the bots
(https://bugs.chromium.org/p/v8/issues/detail?id=10918)

The solution is to keep the JSDataView class as kSerialized but change
its method to do a direct heap access. In this way, its map it will
still be serialized (which was the cause of the bot failure).

In order to keep incrementally skipping serialization, we can introduce
new macros that allow a per-method skip of serialization rather than
per-class.

      [deoptimizer] Refactor --trace-deopt · 5b107848
      Jakob Gruber authored 
      Deopt tracing is both verbose and hard to read. This CL splits verbose
tracing into a new --trace-deopt-verbose flag (s.t. --trace-deopt now
emits single-line events only), refactors tracing methods to all be on
the Deoptimizer class, and clarifies output.

      [liftoff] Do not store any relocation info · ac70b5bf
      Clemens Backes authored 
      Liftoff code is never relocated and never serialized, thus relocation
information is not needed.

This results in slightly less information being printed when
disassembling code, because the disassembler sometimes uses relocation
information to show the kind of a call (e.g. internal wasm call vs.
builtin call). This is an acceptable regression IMO.

      [heap] Evacuate the young generation before the old generation. · 829aefb0
      Ulan Degenbaev authored 
      With the --always_promote_young_mc flag the mark-compact collector
cannot gracefully handle allocation failures when evacuating the young
generation. In some scenarios this causes OOM crashes without invoking
NearHeapLimitCallback.

This CL ensures that the young generation is evacuated before the old
generation because old generation evacuation can be aborted if needed.
Additionally, the CL cleans up usages of CanExpandOldGeneration.
