hello , i can not find the paper via google, so the paper is not a open source ?

Hello, I cannot find the slide in llvm devtmg. Where could I get it?

For the example, why not assign %5 to a callee saved register, and it will be copied to $eax just before return.

[@ryncomaekawa]

He explained that the call uses a special convention that does not save any register, so %5 must be spilled at that point
