| /* |
| * This handler performs a register save for selfVerification mode. |
| * On entry: |
| * Top of stack + 4: a1 value to save |
| * Top of stack + 0: a0 value to save |
| * a0 - offset from rSELF to the beginning of the heapArgSpace record |
| * a1 - the value of regMap |
| * |
| * The handler must save regMap, r0-r31, f0-f31 if FPU, and then return with |
| * r0-r31 with their original values (note that this means a0 and a1 must take |
| * the values on the stack - not the ones in those registers on entry. |
| * Finally, the two registers previously pushed must be popped. |
| * Note: the following registers are not saved |
| * zero, AT, gp, sp, fp, ra |
