Gible Seq Generation Proof
Defining a find block specification
Basically, it should be able to find the location of the block without using the
find_block
function, so that this is more useful for the proofs. There are
various different types of options that could come up though:
The instruction is a standard instruction present inside of a basic block.
The instruction is a standard instruction which ends with a
goto
.The instruction is a control-flow instruction.
For case number 1, there should exist a value in the list of instructions, such that the instructions match exactly, and the indices match as well. In the original code, this instruction must have been going from the current node to the node - 1.
For case number 2, there should be an instruction at the right index again,
however, this time there will also be a goto
instruction in the control-flow
part of the basic block.
For case number 3, there should be a nop
instruction in the basic block, and
then the equivalent control-flow instruction ending the basic block.
In the end though, it seems like two cases are actually enough, as the last two cases are similar enough that they can be merged into one.
Definition all_max {A} (c: PTree.t A) p: Prop := Forall (fun x => x <= p) (map fst (PTree.elements c)). Definition offset (pc pc': positive): nat := Pos.to_nat pc' - Pos.to_nat pc. Section CORRECTNESS. Context (prog : RTL.program). Context (tprog : GibleSeq.program). Let ge : RTL.genv := Globalenvs.Genv.globalenv prog. Let tge : genv := Globalenvs.Genv.globalenv tprog.
Matches the basic block that should be present in the state. This simulates the small step execution of the basic block from the big step semantics that are currently present.
Why does it not need to find the pc’ value using find_block
?
It doesn’t have to find the value because it’s given as an input, and the finding is actually done at that higher level already.

Match the code
The match_code
predicate asserts that for any node in the original
control-flow graph, there is now a basic block in the new control- and data-flow
graph that contains the same instruction, but also that the whole basic block
matches some sequence of instructions starting at the node that corresponds to
the basic block.

Matching states
Initially, the idea was to define the match_states
predicate normally to
defines how to find the correct bb
that should be executed, as well as the
value of pc
. However, this does not quite work when proving the equivalence
of the translation from RTL
to RTLBlock
, because one cannot match one
transition to a transition in RTLBlock. The alternative to this is to include a
proof inside of the match_states
that shows that the execution from the
pc
of the start of the basic block to the current point is the same as the
whole execution (in one big step) of the basic block.
