[LLVMdev] ConstantRange::sub
Sure. I will submit a patch. BTW, what's the difference between the bounds I was expecting APInt NewLower = getLower() - Other.getUpper() + 1; APInt NewUpper = getUpper() - Other.getLower(); and the two you mentioned NewLower = Lower - (Upper-1) NewUpper = (Upper-1) - Lower + 1 They look equivalent to me. Did I miss anything? Thanks. - xi On Jun 22, 2011, at 2:39 PM, Nick Lewycky wrote: >...

[LLVMdev] ConstantRange::sub
Hi, I have a question about ConstantRange::sub(const ConstantRange &Other) at lib/Support/ConstantRange.cpp:524. The code computes the new bounds as follows. APInt NewLower = getLower() - Other.getLower(); APInt NewUpper = getUpper() - Other.getUpper() + 1; Could someone explain this to me? I was expecting something like APInt NewLower = getLower() - Other.getUpper() + 1; APInt NewUpper = getUpper() - Other.getLower(); Thanks. - xi
