- | The addi and mulhi instructions of the device should be specified in the following formats. |
- | 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 r0 (Can be specified only in addi. An error will occur when specified in mulhi.)
|
|
|
addi imm, reg1, r0
|
movhi HIGHW(imm), r0, r1
add reg1, r1
|
Else if reg2 is the same as reg1
|
