Adding an offset to the name refers to that offset from the symbol's address, so
<code>foo+4(SB)</code> is four bytes past the start of <code>foo</code>.

The <code>FP</code> pseudo-register is a virtual frame pointer
used to refer to function arguments.
The compilers maintain a virtual frame pointer and refer to the arguments on the stack as offsets from that pseudo-register.
