Session-qualified imports will be required for Isabelle2018 and help clarify
the structure of sessions in the build tree.
This commit mainly adds a new set of sessions for lib/, including a Lib
session that includes most theories in lib/ and a few separate sessions for
parts that have dependencies beyond CParser or are separate AFP sessions.
The group "lib" collects all lib/ sessions.
As a consequence, other theories should use lib/ theories by session name,
not by path, which in turns means spec and proof sessions should also refer
to each other by session name, not path, to avoid duplicate theory errors in
theory merges later.
This patch adds a generic "post_cap_deletion" step that is called by
finalise_slot. Previous to this, the only caps which had actions
required at this stage were IRQHandlerCaps -- it was required that the
IRQ bitmap be updated after the cap itself was removed (as the
invariants state that for any existing IRQHandlerCap, the corresponding
bit in the IRQ bitmap must be set).
By genericising this, we add the capacity for new, arch-specific post
cap deletion actions to occur in the future.
in addition to the a_type ATCB simplification, the following two are now in the simpset:
"a_type (Endpoint x) = AEndpoint"
"a_type (Notification v) = ANTFN"
In X64 update the following to match the C kernel:
- TCB size-bits (11).
- Endpoint size-bits (4).
- Guard bits (58).
- Message registers.
For all architectures, replace magic numbers with defined constants in
specifications, and as far as possible in proofs:
- tcb_bits in abstract spec.
- tcbBlockSizeBits, cteSizeBits, ntfnSizeBits, epSizeBits in Haskell
spec, Haskell and C refinement proofs.
