Dear all, Attached notunrolled.ll is a module containing reduction kernel. What I'm trying to do is to unroll it in such way, that partial reduction on unrolled iterations would be performed on register, and then stored to memory only once. Currently llvm's unroller together with all standard optimizations produce code, which stores value to memory after every unrolled iteration, which is

Hello everybody, we noticed that llvmgcc4.2-2.2 sometimes generates non-natural loops when compiling to bytecode without any optimizations. Apparently what happens is that the loop header is duplicated, which results in two entry points for the loop. Since this could obstruct subsequent loop optimizations, it might be interesting to further investigate this behavior. To show the problem, I have

Hi, all I want to create a function in LLVM IR, whose type is: void _to_prof( FILE* ptrF); I do it within LLVM, but I don't know how build the parameter type for FILE* ptrF. Best Regards.

...ransformations must be represented in the IR metadata. Second, a pass must carry-out all transformations. Regarding the first part, I suggest storing the loop transformations in a metadata node of the parent function, e.g.: define func() !looptransform !3 [...] br i1 %cond, label %loopheader, ... !loop !1 !1 = distinct !{ !4, !2 } ; LoopID !2 = {"llvm.loop.id", "myloop"} ; Loop name Only the loop id remains a property of the loop. The transformations are stored in the !looptransform metadata node: !3 = { !3, !4, ... } ; Ordered list of loop transfor...
