[llvm-dev] [Question] Is the execution path of clang the same when using clang to compile the same code twice?

[David Blaikie via llvm-dev]

What testing have you done that shows this difference?

In general, Clang/LLVM are intended to be deterministic (same inputs
produce the same output - the execution path to get there can vary in some
cases, due to unordered containers, etc, that should produce the same
output)
