Sorry I just had a mistake, it is interprets code. but my question is how it actually does interpretation.
In generateThunkWithJumpTo function there are 2 lines which I think actually start LLInt. jit.move(JSInterfaceJIT::TrustedImmPtr(bitwise_cast<void*>(target)), JSInterfaceJIT::regT0); jit.jump(JSInterfaceJIT::regT0); If I'm not mistaken this to lines do some preparations And actual interpretation begins only after JSValue result = JSValue::decode(ctiTrampoline(m_ref.code().executableAddress(), registerFile, callFrame, 0, 0, globalData)) in JITCode.h. Am I right? Thanks for attention! On Wed, Nov 14, 2012 at 8:11 PM, Filip Pizlo <[email protected]> wrote: > The LLInt doesn't compile anything to native code, since its an > interpreter.
