arsenm added inline comments.
================
Comment at: llvm/tools/llvm-reduce/deltas/ReduceBranches.cpp:25-33
+static void reduceConditionalBranchesTrue(Oracle &O, Module &Program) {
+ for (auto &F : Program) {
+ for (auto &BB : F) {
+ BranchInst *BI = dyn_cast<BranchInst>(BB.getTerminator());
+ if (BI && BI->isConditional() && !O.shouldKeep())
+ ReplaceInstWithInst(BI, BranchInst::Create(BI->getSuccessor(0)));
+ }
----------------
I was looking at doing this by calling simplifyCFG on each block rather than reimplementing the transform
