- | The add and mulh instructions of the device should be specified in the following formats. |
- | If the following is specified for imm in syntax "add imm, reg2" and "mulh imm, reg2", the assembler executes instruction expansion to generate one or more machine instructions. |
(a) | Absolute expression exceeding the range of -16 to +15, but within the range of -32,768 to +32,767 |
add imm16, reg
|
addi imm16, reg, reg
|
(b) | Absolute expression having a value exceeding the range of -32,768 to +32,767 |
If all the lower 16 bits of the value of imm are 0
add imm, reg
|
movhi HIGHW(imm), r0, r1
add r1, reg
|
Else
add imm, reg
|
mov imm, r1
add r1, reg
|
(c) | Relative expression having !label or %label, or that having $label for a label with a definition in the sdata/sbss-attribute section |
add !label, reg
|
addi !label, reg, reg
|
add %label, reg
|
addi %label, reg, reg
|
add $label, reg
|
addi $label, reg, reg
|
(d) | Relative expression having #label or label, or that having $label for a label having no definition in the sdata/sbss-attribute section |
add #label, reg
|
mov #label, r1
add r1, reg
|
add label, reg
|
mov label, r1
add r1, reg
|
add $label, reg
|
mov $label, r1
add r1, reg
