[LLVMdev] a question to backend

[qiuw at ichaier.com]

Hi, all

I am writting a new backend for a 8-bits target machine(8051). Because the most backends supported by LLVM are for 32-bits targets, most of implementations for 16/32 bits operating had to depend on runtime libraries. In this case, it will decrease the generated code efficency. I found that the LLVM 2.5 supported the PIC16, but the lastest version do not support 8-bits target.  What is the purpose to this change?  Dose it mean that the existing LLVM backend are not available to write 8-bits/16-bits bankend? Thanks a lot.
