[wasm] Add testing opcode to test unsupported opcodes in Liftoff · 9d3a38ae

Andreas Haas authored Jan 14, 2021

Liftoff is not fully feature complete yet. To test that Liftoff can
bailout to TurboFan also for debugging, this CL adds
* an opcode that is only implemented in TurboFan
* a flag that allows that opcode to be compiled with TurboFan
* a bailout for this opcode to Liftoff.

[cpu-profiler] Don't sample wrong thread's stack in profiler · bf9e8d2c

Alex Kodat authored Jan 14, 2021

76217f57 fixed the profiler so it would only sample a thread if
it had the Isolate lock. Unfortunately, this fix missed a timing
window where a thread might have the Isolate lock but might not
have restored the thread-specific data such as thread_local_top_
for the locked thread yet, so the sampler might end up using data
from a different thread.

This doesn't cause any seg faults or the like because the thread
we *meant* to sample has the Isolate lock so the thread we're
accidentally sampling can't mess with any Isolate data but we can
still get incorrect sample data which can be especially obvious if
the accidentally sampled thread is inside code that would never
run on the thread we meant to sample.

Fortunately, we can tell when all thread-specific data has been
restored to the Isolate because thread_state_ in the
PerIsolateThreadData for a thread is set to a non-null value
until everything has been restored, at which point it gets set
to null. So the fix adds a check after the test for the Isolate
lock to check if thread_state_ is null for the thread we mean to
sample. If so, we know all the data in the Isolate is good to go
for sampling.

[regexp] Throw when length of text nodes in alternatives is too large. · 3466daa7

Patrick Thier authored Jan 14, 2021

Offsets in regular expressions are limited to 16 bits.
It was possible to exceed this limit when emitting greedy loops where
the length of text nodes exceeded 16 bits, resulting in overflowing
offsets.
With this CL we throw a SyntaxError "Regular expression too large" to
prevent this overflow.

[wasm] Mark loop exits in wasm-generated TurboFan graphs · a358c2eb

Manos Koukoutos authored Jan 14, 2021

Changes:
- Add --wasm-loop-unrolling flag. Everything in this CL happens behind
  this flag.
- In decoding, DoReturn does not take returned values as an argument.
  It is now the responsibility of graph-builder-interface.cc to extract
  these values. Note that this is what was already happening in Liftoff.
- In pipeline.cc, add phase to remove loop exits after generating the
  turbofan graph.
- Explicitly disallow calling FallThruTo() on loops.
- Add loop assignments and loop header node to Control type in
  graph-builder-interface.cc. Assign them in Loop().
- Main change: Add loop exit nodes to wasm-generated graphs. For
  details, consult this design doc: https://docs.google.com/document/d/1AsUCqslMUB6fLdnGq0ZoPk2kn50jIJAWAL77lKXXP5g
- Inline PrepareForLoop().

cppgc: Add support for const T in Member and friends · 3494110a

Michael Lippautz authored Jan 13, 2021

Adds support for Member<const T> by keeping the untyped storage in
MemberBase const, which is stronger than the required constness. All
accesses go through BasicMember which can re-add the appropriate
constness specified by the user.

The same concept is applied to all Member and Persistent handles.

[wasm-simd][liftoff][arm64] Prototype load lane · 2f447ad6

Zhi An Ng authored Jan 13, 2021

Prototype load lane instructions on ARM64 Liftoff.

We extract a helper function that will convert a MemOperand that uses a
register offset or a non-zero immediate offset, into a MemOperand that
uses a temporary to store base+offset and immediate offset of 0. Some
instructions, ld1r or ld1 don't support offset, and will use this helper
to get the correct MemOperand.
