 9.18.2.2 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)
