The two pairs of instructions LDMIA, STMDB and LDMFD, STMFD do exactly the same things. Why do these two pairs have different or alternative mnemonics? Why does the first pair have different suffixes IA and DB? Why does the second pair have the same suffix FD?
What will be an ideal response?
There is no need for such a flexible/involved naming system. ARM has decided to allow you to name the instructions according to either what they do or how they do it. Instructions with the FD suffix describe the type of stack. If it is full descending it means that the stack grows towards low addresses (the pointer is decremented on storing and incremented on popping). The term full indicates that the next item on the stack is the element pointed at (not the next free item).
The suffix DB indicates decrementing before and is used with a store. IA indicates incrementing after and is used with a load.
