Hello, Is it possible to prevent duplication of call sites for specific functions (while still maintaining -O3 optimization level)? For example, the following C code: ------------------ if (cond1) a=2; llvm.memory.barrier(...); ------------------ is turned by clang with -O2 into something like this: ------------------ if (cond1) a=2; llvm.memory.barrier(...); else
