Hi I would like to initialize a global variable to the address of a function. Looking at how clang compiles the C code below, i see @main_ptr = global i8* bitcast (i32 ()* @main to i8*), align 8 but how do i generate i8* bitcast (i32 ()* @main to i8*), align 8 in LLVM IR and use it as initializer to a GlobalVariable. I know i will need to use the bitcast instruction. but as far i as i
