| 32 | # There is a number of MIPS ABI in use, O32 and N32/64 are most

| 34 | # one picks the latter, it's possible to arrange code in ABI neutral
|
|---|
| 35 | # manner. Therefore let's stick to NUBI register layout:

|

| 41 | #

|
|---|
| 43 | # interoperability:
|
|---|
| 44 | #
|
|---|
| 45 | # - never ever touch $tp, "thread pointer", former $gp [o32 can be
|
|---|
| 46 | # excluded from the rule, because it's specified volatile];
|
|---|
| 47 | # - copy return value to $t0, former $v0 [or to $a0 if you're adapting
|
|---|
| 48 | # old code];
|
|---|
| 49 | # - on O32 populate $a4-$a7 with 'lw $aN,4*N($sp)' if necessary;
|
