[LLVMdev] llc -load....

[s88]

Thank you...
I am preparing to build a simple C compiler for our new architecture.
According to your suggestion. I try to dynamically load my backend.
But I got the error message :  
llc :  target 'Your_Arch' does not support static compilation!

could you tell me where is this problem?
