The old LLVM pass manager is deprecated and should not be used anymore. Moreover, the pass manager builder (which we used to set up a pass pipeline) is actually removed from LLVM entirely in LLVM 17: https://reviews.llvm.org/D145387 https://reviews.llvm.org/D145835 The new pass manager does change the binary size in many cases: both growing and shrinking it. However, on average the binary size remains more or less the same. This is needed as a preparation for LLVM 17.
