search for: findinputsoutputs

Hi there, I want to get input and output values from a loop. For this I am doing something like this: DominatorTree &DT = getAnalysis<DominatorTreeWrapperPass>().getDomTree(); CodeExtractor Extractor(DT, *L); Extractor.findInputsOutputs(inputs, outputs); When I print the input and output values for the following test code: void aFunc(void) { int sum=0; puts("aFunc()"); for (int i = 0; i < 10; i++) { int fact=i*2; sum=sum+i+fact; } printf("%d",sum); } I get t...

Hi, I have a question about ExtractLoop() in CodeExtractor.cpp. The sample code is a simple list traversal, as attached. The generated bitcode (from llvm-gcc -O1) is shown below. -------------------------------------------------------------------------------------------------------------------------------- define i32 @walk(%struct.node2* %list2) nounwind { entry: %0 = icmp eq

I second the fact that a way to outline specific function regions independently of the partial inliner sound very useful. I am not sure however if we would want a mode within the partialInliner or something completely independent. As a general question, does anybody has a clear idea of what are the constraints on the region CodeExtractor is currently able to handle ? Going through the code, it
