Do you mean that "normal" SSA phi elimination algorithm is DemotePHI()?

...do everything that you are trying to re-implement. 2) Have you looked at the C backend? It recreates loops. It may not create "for" loops but you can hack on it to do that. 3) The way you are converting out of SSA is wrong. You will suffer from lost copies. You should look at using demotePHI(). see include/ llvm/Transforms/Utils/Local.h 4) LLVM will compute your trip counts for you, use LoopInfo. You need to be in SSA form to do this. -Tanya On Feb 1, 2008, at 11:51 PM, Seung Jae Lee wrote: > Dear Prof.Adve and Bill, > > I deeply appreciate your comments and concerns. &...

Dear Prof.Adve and Bill, I deeply appreciate your comments and concerns. (Please forgive my late response. I've tried some more cases to make this issue) As Prof.Adve mentioned, I need to explain exactly what my problem is, but I have no good ability that I can explain it in this plain text space. For this reason, I made a .pdf file and linked it as follows:

Hello, Wojtek. I owe much to you. Thank you. My HL code should be simple without any 'goto','break' and so on. Simple as just loops with 'for' and 'if's inside it, so your comment looks helpful. I'll try. Just one thing which concerning me is demotePHI() I couldn't find it in 1.9 so seems to me another installation of the newest version of LLVM. Anyway, Thank you.
