[LLVMdev] instructions copy

[Yuxi Chen]

Hi,

I want to copy some dependent statements, like a = b, b = c, from one basicblock to another basicblocks.
Because of SSA, a = b, will be like %1 = load %b, store %1, %a.
If I just use clone() method in Instruction class, it will be like <badref> = load %b, store <badref>, %a.
If I need remap the virtual registers, this map just will affect the whole module? And how to use it? I am a bit confused.

Any suggestion will be appreciated.

Best,
