Sorry for forgetting to reply all... It works! Thank you very much! But I also wonder how do you know this function will work while there are no documents noticing that. I try learning LLVM by reading its code, but soon feel lost in so many functions. Just like I have many tools, but don't know which to use and what difference it could make. Is there some better ways to learn LLVM? On Wed,

Hi, I am writing a loop pass to replace the backedge with an edge from latch to exit. Now I just replace the terminator of latch with another BranchInst, and the loop will not be a loop after my pass. However, it turns out a failure of loopverify after executing my pass: opt: ~/llvm/llvm-trunk/include/llvm/Analysis/LoopInfoImpl.h:297: void llvm::LoopBase<N, M>::verifyLoop() const [with

Hello everyone, Sorry to bother you. I'm an undergraduate, and I'm trying to finish my graduation project using LLVM. In this project, I hope to transform all loop in program to condition statement. For example, Before transformation: for (int i = 0; i < 5; i++) a++; After transformation: int i = 0; if (i < 5) a++; i++; The idea is very clear, however, I'm a newbie to LLVM.

R builds fine with the 2.95.2 combo, it also builds fine with gcc 2.95.2 and g77 3.1. But using gcc 3.1 or gcc 3.3 gives the familiar problem that I mentioned before (although

Hello list. I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without modifications. How did I try it? Created a (non-root) build environment (not a mock ) Installed the kernel.scr.rpm and did a rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee prep-out.log The build failed at the end: Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL Checking
