#### 9.31.3 Nios II Machine Relocations

`%hiadj(`expression`)`
  Extract the upper 16 bits of expression and add one if the 15th bit is set.

  The value of `%hiadj(`expression`)` is:

                ((expression >> 16) & 0xffff) + ((expression >> 15) & 0x01)

  The `%hiadj` relocation is intended to be used with the `addi`, `ld` or `st` instructions along with a `%lo`, in order to load a 32-bit constant.

                movhi r2, %hiadj(symbol)
                addi r2, r2, %lo(symbol)

`%hi(`expression`)`
  Extract the upper 16 bits of expression.

`%lo(`expression`)`
  Extract the lower 16 bits of expression.

`%gprel(`expression`)`
  Subtract the value of the symbol `_gp` from expression.

  The intention of the `%gprel` relocation is to have a fast small area of memory which only takes a 16-bit immediate to access.

                	.section .sdata
                fastint:
                	.int 123
                	.section .text
                	ldw r4, %gprel(fastint)(gp)

`%call(`expression`)`
`%call_lo(`expression`)`
`%call_hiadj(`expression`)`
`%got(`expression`)`
`%got_lo(`expression`)`
`%got_hiadj(`expression`)`
`%gotoff(`expression`)`
`%gotoff_lo(`expression`)`
`%gotoff_hiadj(`expression`)`
`%tls_gd(`expression`)`
`%tls_ie(`expression`)`
`%tls_le(`expression`)`
`%tls_ldm(`expression`)`
`%tls_ldo(`expression`)`
  These relocations support the ABI for Linux Systems documented in the Nios II Processor Reference Handbook.
