Web11 sep. 2013 · In fact the ldr= pseudo instruction is a bit more clever than it looks, as it will check if the given constant can be represented by an Operand 2 immediate and will generate a mov instruction if it can. A mov instruction will be faster than an ldr instruction as there is no need to read the constant from memory, also resulting in memory savings.
