The difference in binaries must be caused by some runtime difference of a compiler.
- drdrey 3y agoThat's right, look at this thread for example: https://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20140512/217038.html https://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20... The Global Value Numbering pass in LLVM was iterating over `DenseMap<BasicBlock*, ...>`, so the iteration order was dependent on the value of BasicBlock pointers. This could lead to the same source files and compiler producing different binaries.
