Hello, I'm studying how the SCEV analyzis works and how to use it and I could not create an example where the SCEV analyzis identifies an expression as "SCEVAddRecExpr". Aren't the expressions below the kind of pattern that should be represented as a "AddRecExpr" ? SCEV: (1 + (2 * %3) or SCEV: (%1 + (2 * %3) or...

...reating new thread/loops for each SCCs. The last step is responsible to insert communication between the stages to enable data forwarding and synchronization. The main goal of this project is to implement DSWP as a pass in the LLVM opt tool, however as a "side-effect" of this project new analyzis can be added to opt such as -print-pdg to print the program dependence graph in a DOT[3] format and/or -print-ddg to print the data dependence graph in DOT format. ### Schedule of Deliverables Week 01: The first week I'll be involved in constructing the control dependence graph. Week 02: T...

...is adding very little improvement over AA, it seems. I don't have any failing test cases right now, so it may be that this patch actually fixed my problem. However, right now it is confusing to have the whole algorithm written around memory operands and at the same time allow register / offsets analyzis in the midst of things. It would be good to rewrite that part like you explained. What are your current thoughts about this? -----Original Message----- From: Hal Finkel [mailto:hfinkel at anl.gov] Sent: den 23 december 2014 18:11 To: Sanjin Sijaric Cc: Mattias Eriksson V; llvmdev at cs.uiuc.edu;...
