movea   imm, reg1, reg2
movhi   HIGHW(imm), reg1, reg2

movea   imm, reg1, reg2
movhi   HIGHW1(imm), reg1, r1
movea   LOWW(imm), r1, reg2

(b)

Relative expression having #label or label, or that having $label for a label having no definition in the sdata/sbss-attribute section

movea   #label, reg1, reg2
movhi   HIGHW1(#label), reg1, r1
movea   LOWW(#label), r1, reg2
movea   label, reg1, reg2
movhi   HIGHW1(label), reg1, r1
movea   LOWW(label), r1, reg2
movea   $label, reg1, reg2
movhi   HIGHW1($label), reg1, r1
movea   LOWW($label), r1, reg2
