POC showing the V8 engine running in an iOS application. Currently only the x86_64 and arm64 architectures are supported.

The --jitless mode in which V8 is running is explained in the following document

The sample iOS application runs the Octane 2.0 Benchmark and outputs the results.

In order to build the V8 engine for iOS and produce static libraries follow those steps:

• Get depot_tools

git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
export PATH=`pwd`/depot_tools:"$PATH"

• fetch v8 (this will create a v8 repo folder automatically checking out the master branch)

• Apply patches: apply_patch.sh

• Run build.sh

The compiled fat static libraries will be placed inside the v8/dist folder.

Using the Octane benchmark we have compared the performance of V8 against JSC used in the ios-runtime.

The tests have been executed on an iPhone 7 (iOS version 11.2.1)
