From the fact that nobody is replying I guess there's no easy way to do what I asked. Can you just confirm then that the following is a meaningful way to do it? * D_b <- set of dominators of BB b * S_b <- set containing b and its successors (optional) * VD_b <- set of the values defined in D_b * VS_b <- set of the values with uses in S_b (optional) * LV_b <- VD_b ∩ VS_b, i.e. the live values (optional, otherwise LV_b = VD_b)...

Suppose I have in my CFG (among others) two basic blocks A and B, with an edge from A to B. I need to do the following: * get the set S of live values across that edge * map each of them to another value (S->S') * replace - in B and its successors - all the uses of values in S with the mapped values (S') Does LLVM provide an easy way to do this (because I can't

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
