| Branch name | Clang branch name | Description |
|---|---|---|
| base | base | Baseline (LLVM 6.0, official release) |
| nointptrfold | base | (base +) No inttoptr(ptrtoint p)-> p fold |
| correct | base | All known unsound optimizations disabled |
| psub | psub | (correct +) Add 'psub' intrinsics |
| optimized | psub | (psub +) Sound optimizations added (GVN, ..) |
| i8canon | psub | (optimized +) Add i64->i8* canonicalization |
| pass to support SLP vectorization |
