有没有人知道基于堆栈的机器的开源LLVM后端的任何示例？我需要这个用于教育目的.

问候.我试着让孩子控制应用程序.键盘记录器是此应用程序的一部分.我使用CGEventTapCreate来观看键盘.这很好用,但有时我会重复关键事件.它们没有设置[NSEvent isARepeat],只是重复.例如,我可以输入"qwerty"但应用程序会获取这些字符的关键事件:"qqwweerrttyy".也许有人经历过这样的喜欢吗？我在10.5和10.6上都遇到了这个问题(两者都是英特尔).

我在这里发布键盘记录器安装和处理程序方法:

- (BOOL)installKeyboardLogger
{
  CGEventMask keyboardMask = CGEventMaskBit(kCGEventKeyDown);
  CGEventMask mouseMask = CGEventMaskBit(kCGEventMouseMoved) |   CGEventMaskBit(kCGEventLeftMouseDown) |
      CGEventMaskBit(kCGEventRightMouseDown);

  CGEventMask mask = keyboardMask + mouseMask;// + mouseMask;//CGEventMaskBit(kCGEventKeyDown) | CGEventMaskBit(kCGEventMouseMoved);

  // Try to create keyboard-only hook. It will fail if Assistive Devices are not set.
  mMachPortRef =  CGEventTapCreate(
                                   kCGAnnotatedSessionEventTap,
                                   kCGTailAppendEventTap, // kCGHeadInsertEventTap
                                   kCGEventTapOptionListenOnly,
                                   keyboardMask,
                                   (CGEventTapCallBack)eventTapFunction,
                                   self );
  if (!mMachPortRef)
    [mLogFile logNeedAssistiveDevice: @"Can't install keyboard hook."];
  else
    CFRelease(mMachPortRef);

  mMachPortRef = CGEventTapCreate(
                                  kCGAnnotatedSessionEventTap,
                                  kCGTailAppendEventTap, // kCGHeadInsertEventTap
                                  kCGEventTapOptionListenOnly,
                                  mask,
                                  (CGEventTapCallBack)eventTapFunction,
                                  self );
  if (!mMachPortRef)
