<pre>This is the code my patch generates:
move a0,s8
move a1,zero
sw v1,-12(s8)
sw v0,-16(s8)
lw t6,-20(s8)
lw v0,-24(s8)
sw t5,-36(s8)
sw t4,-40(s8)
lw v1,-12(s8)
lw t4,-16(s8)
move a2,v0
move a3,t6
sw t2,16(sp)
sw t3,20(sp)
sw t4,24(sp)
sw v1,28(sp)
sw t3,-28(s8)
sw t2,-32(s8)
lw v0,-36(s8)
lw v1,-40(s8)
sw v1,32(sp)
sw v0,36(sp)
li t0,2
sw t0,28(s8)
lui t9,0x1d3
ori t9,t9,0x33f4
jalr t9
nop
I am wondering whether there is a way to have basePayload and baseTag load directly into the right argument registers, which would save these two moves.</pre>
