Hi, I want to know the variable mapping between the source and llvm bytecode. It seems that current llvm debugging information cannot provide this mapping directly. Here is my examples (llvm 2.7). In this exmaple, I want to know the mapping: tmp<--->%4. But current llvm's debugging information can only provide that the instruction "%4 = add nsw i32 %3, 2" is at line 3 in

Eli, Thanks very much for your reply. That's what I want to know. It works for this example. But I usually have to deal with the optimized bytecode with "-O". See the example: ************** C source ************** int h (int j, int i) { int tmp; tmp = j+i+2; return tmp; } +++++++++++++++++++++++++++++++++++++ .ll file: ; ModuleID = 'simplecase.c' target

Hi, I want to get the mapping between C source's variables and bytecode variables. It seems that llvm doesn't provide this mapping, so I think a walk-around method is to get the instruction's mapping. I have to use llvm-gcc, not clang. Any advice? Thanks.
