[wasm][test] Extend jump-table stress test to all archs. · 4566cb40

Michael Starzinger authored Feb 20, 2019

This extends the "test-jump-table-assembler" stress test to supported
architectures. Note that on both PPC and S390 the tests flushes out the
race during jump table patching pretty reliably. Fixing this issue is
outside the scope of this change, this just ensures test coverage exists
but keeps the test in question disabled.

[wasm] Use shared mutex for background compile token · 2664a259

Clemens Hammacher authored Feb 20, 2019

This introduces a new {base::SharedMutex}, which mimics
{std::shared_mutex}, available in C++17.
It is being used for synchronizing the WebAssembly background compile
tasks. This removes a lot of unnecessary contention, leading to
synchronization of background tasks that should be able to run in
parallel ideally.
Locally, this reduces Liftoff compilation time by more than 20 percent.

[Torque] Do Witness Rechecks() at loop starts · 26a2aee3

Since these Recheck() calls are usually combined with a bailout,
doing them at the end of loops means we have to increment one or
more bailout variables, which is hard to understand.

This CL changes to automatic growth that is invisible to the user.

[x86] Use pushes to setup the FunctionCallbackArguments on the stack. · 18772548

Benedikt Meurer authored Feb 19, 2019

On Intel processors it seems to be generally beneficial to use pushes
instead of explicit stack massaging to allocate the function callback
arguments on the stack for the API callback.

This yields a 5% improvement on the API callback performance, and
recovers an earlier regression (which was probably due to changing this
code to use movs instead of pushes).
