webkit-llint-gcc-lto.patch
When compiling WebKit with GCC's Link Time Optimizations, the functions included from DerivedSources/JavaScriptCore/LLIntAssembly.h, included from Source/JavaScriptCore/llint/LowLevelInterpreter.cpp, aren't expodes and linking of libJavaScriptCore fails.
This patch checks if GCC is used and if it is of versions which supports LTO, and if it is, disables the -flto flag for one compilation unit, LowLevelInterpreter.cpp, with GCC's #pragma directive.</pre>
