// This is the implementation of AndroidThreading, which is declared in
// JavaScriptCore/wtf/android/AndroidThreading.h. It is provided here, rather
// than in its own source file, to avoid linker problems.
//
// By default, when building a shared library, the linker strips from static
// libraries any compilation units which do not contain any code referenced from
// that static library. Since
// AndroidThreading::scheduleDispatchFunctionsOnMainThread is not referenced
// from libwebcore.a, implementing it in its own compilation unit results in it
// being stripped. This stripping can be avoided by using the linker option
// --whole-archive for libwebcore.a, but this adds considerably to the size of
// libwebcore.so.
