  Which also does not affect cmov conversion. Every time this comes up I bring up this long-standing LLVM bug: https://bugs.llvm.org/show_bug.cgi?id=40027 https://bugs.llvm.org/show_bug.cgi?id=40027

    __builtin_unpredictable is gonna be fixed in LLVM/clang 17: https://github.com/llvm/llvm-project/commit/09515f2c20111628ce81ad5f40e12e5f6af5ed2f https://github.com/llvm/llvm-project/commit/09515f2c20111628... (also, bugs.llvm.org is old; the more up-to-date (but still open) issue is https://github.com/llvm/llvm-project/issues/39374 https://github.com/llvm/llvm-project/issues/39374)
