Description Csaba Osztrogonác 2015-04-10 08:07:01 PDT
http://trac.webkit.org/changeset/182483 enabled in on iOS AArch64, we 
should enable it to get better performance and decrease maintenance cost.

It depends on fixing FTL JIT with LLVM 3.6

We will have another problem with it:
"llvmForJSC.dylib: for the -regalloc option: Cannot find option named 'basic'!"

Looks like the dylib wasn't linked with the --whole-archive option. The register allocators are registered by static initializers. Without the --whole-archive option the "basic" register allocator will be dead stripped out.

There is no LLVM based FTL JIT long time ago.
