Oh, right, I'll just change the comment to make it more clear.
e.g.:
lea 1234(%rip), %rdi, where %rip has the value 2222
is changed to:
movabs %rdi, 3456 (where 3456 = 1234 + 2222)
So we just compute the result of the lea instruction, and put it into the immediate value used in movabs. So it is a movabs with an immediate operand, doesn't dereference anything.

Done.
