Commit d20f80780e053dfa3664858c9ac8be15951a035d by jdoerfert [Attributor][FIX] Do not apply h2s for arbitrary mallocs H2S did apply to mallocs of non-constant sizes if the uses were OK. This is now forbidden through reording of the "good" and "bad" cases in the conditional. llvm-svn: 374698

Commit af6e4797330b597b50469bbadd4a55ef26536ea9 by jdoerfert [Attributor][FIX] Ensure h2s doesn't trigger on escaped pointers We do not yet perform h2s because we know something is free'ed but we do it because we know the pointer does not escape. Storing the pointer allows it to escape so we have to prevent that. llvm-svn: 374699

Commit 4056e7f02a407971ef837bb2eff4724cfd475c4d by jdoerfert [Attributor][FIX] Avoid splitting blocks if possible Before, we eagerly split blocks even if it was not necessary, e.g., they had a single unreachable instruction and only a single predecessor. llvm-svn: 374703
