[LLVMdev] Mapping registers into memory address
Hi all,
I'm working on using LLVM to generate ARM code for Android's Dalvik VM.
I translated some DEX bytecode to LLVM IR, and now I wnat to translate
these IR into ARM assembly by using llc.
But there are some ABI problems (Register mapping) should be solved.
Dalvik VM stores virtual register in the fixed memory address.
For example,
v0 -> [r5,#0]
v1 -> [r5,#4]
v2 -> [r5,#8]
v3
