##### 9.20.2.2 Relocatable Expression Modifiers

The assembler supports several modifiers when using relocatable addresses in LM32 instruction operands. The general syntax is the following:

         modifier(relocatable-expression)

`lo`
  This modifier allows you to use bits 0 through 15 of an address expression as 16 bit relocatable expression.
`hi`
  This modifier allows you to use bits 16 through 23 of an address expression as 16 bit relocatable expression.

  For example

                ori  r4, r4, lo(sym+10)
                orhi r4, r4, hi(sym+10)

`gp`
  This modified creates a 16-bit relocatable expression that is the offset of the symbol from the global pointer.

                mva r4, gp(sym)

`got`
  This modifier places a symbol in the GOT and creates a 16-bit relocatable expression that is the offset into the GOT of this symbol.

                lw r4, (gp+got(sym))

`gotofflo16`
  This modifier allows you to use the bits 0 through 15 of an address which is an offset from the GOT.
`gotoffhi16`
  This modifier allows you to use the bits 16 through 31 of an address which is an offset from the GOT.

                orhi r4, r4, gotoffhi16(lsym)
                addi r4, r4, gotofflo16(lsym)
