Wasm tier-up first compiles the whole module using Liftoff, and then using Turbofan. The idea is to achieve fast start-up times by first running Liftoff-compiled code. In the meantime we finish compilation with Turbofan, and replace the Liftoff-compiled code as soon as Turbofan finished compilation, thus achieving high performance. Tier-up is enabled through the flag FLAG_wasm_tier_up.

Andreas Haas authored
WebAssembly.instantiate is polymorphic, it can either take a module object as parameter, or a buffer source which should be compiled first. To share code between the two implementations, the module object was first passed to a promise (i.e. which is the result of compilation). However, passing the module object to a promise has a side effect if the module object has a then function. To avoid this side effect I remove this code sharing and call AsyncInstantiate directly in case the parameter is a module object.

Kenton Varda authored
For use cases with a large number of threads or a large number of isolates (or both), ThreadDataTable can be a major performance bottleneck due to O(n) lookup time of the linked list. Switching to a hash map reduces this to O(1). Example 1: Sandstorm.io, a Node.js app that utilizes "fibers", was observed spending the majority of CPU time iterating over the ThreadDataTable. See: https://sandstorm.io/news/2016-09-30-fiber-bomb-debugging-story Example 2: Cloudflare's Workers engine, a high-multi-tenancy web server framework built on V8 (but not Node), creates large numbers of threads and isolates per-process. It saw a 34x improvement in throughput when we applied this patch. Cloudflare has been using a patch in production since the Workers launch which replaces the linked list with a hash map -- but still global. This commit builds on that but goes further and creates a separate hash map and mutex for each isolate, with the table being a member of the Isolate class. This avoids any globals and should reduce lock contention. Bug: v8:5338 Change-Id: If0d11509afb2e043b888c376e36d3463db931b47 Reviewed-on: https://chromium-review.googlesource.com/1014407Reviewed-by:

On AArch64, we can't push arguments one by one because sp must always be 16 byte aligned. This patch adds a LiftoffStackSlots class which holds everything which has to be pushed. This way, on AArch64, we will be able to reserve the needed space and eventually add some padding. Then, all pushes will be converted to stores into this reserved space.

At the moment, the isolate is allocated and initialized in a single step. This has the downside that the platform cannot register the isolate before the isolate gets initialized, and therefore the platform is not available for the isolate during initialization. With this CL we register the uninitialized isolate on the platform and initialize the isolate after that. This change is needed to allow the creation of task runners already during the initialization of the isolate.
