...es required by an analysis pass should be preserved. Say, I have an analysis pass which requires another analysis pass called *SomeAnalysis* and I have not added *AU.addPreserved<SomeAnalysis>() *to my pass. Would the pass manager still considers the *SomeAnlaysis *as preserved? -- Regards, DTharun -------------- next part -------------- An HTML attachment was scrubbed...

Hi Dean, I have tried with -instr-map-1 and -instr-map-2, it didn't work.

Hi, I am working with SCEVs, I see the unsigned division of SCEVs, it is not immediately clear to me why the signed division of SCEV expressions is not supported by SE? I would appreciate if some could clarify or point me to some links. -- Regards, DTharun -------------- next part -------------- An HTML attachment was scrubbed...

Hello, I have studied register allocation in theoretical aspects and exploring the same in the implementation level. I need a minimal testcase for register spilling to analyze spilling procedure in llvm. I tried with a testcase taking 20 variables but all the 20 variables are getting stored in the stack using %rbp. Maybe my live variable analysis is wrong. Please help me with a minimal testcase
