高度怀疑这样做得动机。
为什么要多加一层呢？ 有一定必要吗？ java 已经被 sun 劫持了。 windows 也想通过同样方式劫持一批。

to prolj:

http://llvm.org/ :

A virtual instruction set - LLVM is a low-level object code representation that uses simple RISC-like instructions, but provides rich, language-independent, type information and dataflow (SSA) information about operands. This combination enables sophisticated transformations on object code, while remaining light-weight enough to be attached to the executable. This combination is key to allowing link-time, run-time, and offline transformations.

Note that optional LLVM components can be used to build high-level virtual machines and other systems that need these services

----------------

  I think this is the diff between LLVM and gcc , and also, that reminds me java.


好像又发错了， ~

不过prolj 对这方面很在意也很在行...
