Reconciling High-level Optimizations and Low-level Code in LLVM
This is the implementation of OOPSLA'18 LLVM memory model.
You can clone corresponding Clang branches from https://github.com/snu-sf/clang-twin.
|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|
