> This patch fixes two issues in spillgen:
> 1) Allocation register to dead-definition does not mark the register as occupied if it
was obtained by evict operation.
> 2) Allocation register to complex operand of jump instruction may cause inserting mov
instruction after jump.
> Both these problems are rare and hard to reproduce.
