Hello everyone, Consider we have this following set of code: int foo() { int a,b; a = __builtin_XX(0x11); b = __builtin_XX(0x11); return a+b; } The problem currently is that LLVM eliminated the second call and copied the result from the first call into a new set of registers. Is there is a way to force LLVM to generate two explicit calls to a builtin function. The builtin takes in an integer

Please open a bugzilla ticket and attach your testcase. It will allow us to debug and fix the problem.
