Non-determinism in LLVM codegen
...ontinue to be always forward iterated.
This behavior cannot be overridden as the above flag is available
only in builds with assertions enabled.
Currently, the following unit tests are failing in Release+Asserts mode
due to the difference in SmallPtrSet iteration order:
Clang :: Analysis/keychainAPI.m
Clang :: Analysis/malloc.c
Clang :: Rewriter/objc-modern-metadata-visibility.mm
Clang :: SemaCXX/warn-loop-analysis.cpp
LLVM :: Transforms/SimplifyCFG/bug-25299.ll
Next Steps:
I plan to extend this behavior to the iteration of other unordered
containers (like DenseMap, etc)....

Non-determinism in LLVM codegen
...change.
If there is a difference in codegen then it would mean that the codegen
is sensitive to the iteration order of SmallPtrSet.
I ran make check-all with and without my patch and I see the following
additional failures due to iteration of SmallPtrSet in reverse order:
/ Clang :: Analysis/keychainAPI.m//
// Clang :: Analysis/malloc.c//
// Clang :: Rewriter/objc-modern-metadata-visibility.mm//
// Clang :: SemaCXX/warn-loop-analysis.cpp//
// LLVM :: Transforms/LoopVectorize/consecutive-ptr-uniforms.ll//
// LLVM :: Transforms/SimplifyCFG/bug-25299.ll//
// LLVM :: Transforms/Util/...

Wait, so you committed a patch that breaks these tests? Should you fix
them first?
IIUC, LLVM_A...
