Hi, I have two questions about optimizations performed by llvm. Consider these simple functions: int x(int b) { return b?4:6; } int y() { return x(0); } int x2() { return 5; } int y2() { return x2(); } the optimized bitcode (with clang + opt -std-compiler-opts) is: define i32 @y(...) nounwind { entry: ret i32 6 } define i32 @y2(...) nounwind { entry: %call = call i32 (...)* @x2( ) ;
