Arm to llvm-ir

[chlizheng]

Hi.
I want to translate arm assembly code to llvm-ir staticly for a try by translating simple code. In my opinion, I should translate arm instruction to llvm-ir one by one, and then replace arm instructions by a script. Maybe I think it too simple.

But I didn't find enough data to do this. It seems that the instructions about jump is difficult and the list of AMT is too large. What's more, I'm not sure how to translate some arm instructions to llvm-ir, and how to design whole infrastructure of target .ll file just according to assembly code?

Do you have some reference data about the translation job? And could you give me some references?
best regards.
