Description Akos Kiss 2014-11-02 17:59:56 PST 
When trying to enable FTL JIT for GTK (by building with: Tools/Scripts/update-webkitgtk-libs && Tools/Scripts/update-webkitgtk-libs llvm && Tools/Scripts/build-jsc --gtk --ftl-jit), there are several failures.

First, when building, CMake complains about LIBCXXABI:

CMake Error at Source/cmake/OptionsGTK.cmake:317 (find_package):
  By not providing "FindLIBCXXABI.cmake" in CMAKE_MODULE_PATH this project
  has asked CMake to find a package configuration file provided by
  "LIBCXXABI", but CMake did not find one.

If we overcome that, then LLVM bails out with some runtime errors, e.g.:
  
sunspider-1.0/string-validate-input.js.ftl-eager: jsc: RuntimeDyldELF.cpp:283: void llvm::RuntimeDyldELF::resolveX86_64Relocation(const llvm::SectionEntry &, uint64_t, uint64_t, uint32_t, int64_t, uint64_t): Assertion `RealOffset <= (2147483647) && RealOffset >= (-2147483647-1)' failed.
sunspider-1.0/string-validate-input.js.ftl-eager: Aborted (core dumped)
sunspider-1.0/string-validate-input.js.ftl-eager: ERROR: Unexpected exit code: 134
