- | The satsubi instructions of the device should be specified in the following formats. |
- | SATSUBI imm16, reg1, reg2 |
- | If the following is specified for imm, the assembler executes instruction expansion to generate multiple machine instructions. |
(a) | Absolute expression having a value exceeding the range of -32,768 to +32,767 |
<1> | If all the lower 16 bits of the value of imm are 0 |
If reg2 is the same as reg1
satsubi imm, reg1, reg2
|
movhi HIGHW(imm), r0, r1
satsub r1, r2
|
Else
satsubi imm, reg1, reg2
|
movhi HIGHW(imm), r0, reg2
satsubr reg1, reg2
|
If reg2 is the same as reg1
satsubi imm, reg1, reg2
|
mov imm, r1
satsub r1, reg2
|
Else
satsubi imm, reg1, reg2
|
mov imm, reg2
satsubr reg1, reg2
|
(b) | Relative expression having #label or label, or that having $label for a label having no definition in the sdata/sbss-attribute section |
If reg2 is the same as reg1
satsubi #label, reg1, reg2
|
mov #label, r1
satsub r1, reg2
|
satsubi label, reg1, reg2
|
mov label, reg2
satsub r1, reg2
|
satsubi $label, reg1, reg2
|
mov $label, reg2
satsub r1, reg2
|
Else
satsubi #label, reg1, reg2
|
mov #label, reg2
satsubr reg1, reg2
|
satsubi label, reg1, reg2
|
mov label, reg2
satsubr reg1, reg2
|
satsubi $label, reg1, reg2
|
mov $label, reg2
satsubr reg1, reg2
|
