[LLVMdev] Fail to unroll loop on simple examples.
...ss "-loop-rotate" before "-indvars", then the loop is successfully unrolled. However, I think this pass may increase the size of the code for all loops, including the loops that cannot be unrolled. Is this a bug? Or is there any other pass that can help UnrollLoop? -- Claude Helmstetter +86 186 0895 4884 / +33 6 32 99 06 00 http://formes.asia/people/Claude.Helmstetter/ -------------- next part -------------- An HTML attachment was scrubbed...

...that is on line 116 (or so) in lib/Transforms/Utils/LoopUnroll.cpp Based on a quick look at the source code, this looks like a bug in LLVM to me, e.g. perhaps the test is applied on a wrong block? But more probably I am just missing something. --Pekka Nikander On 2010-07 -01, at 13:48 , Claude Helmstetter wrote: > Hi all, > > I have tried to use the loop-unroll pass on a large example, but without success.
