Including version information in the spec document is tricky, because
Isabelle will rebuild the session whenever it sees that session inputs
(including document sources) have changed. Since ASpec is close to the
root of our session hierarchy, frequently changing version information
causes excessive rebuilds during development.
This commit avoids excessive rebuilding by building the document (with
version information) in a separate ASpecDoc session. The ASpecDoc
session is identical to the previous version of the ASpec session, but
is not the parent of any other sessions. The ASpec session is used as
the basis for other sessions, but has document-only inputs removed, and
also has document builds disabled.
This partially reverts a recent change which adds these.
Unfortunately, including the ARCH and git-id files in the ROOT file
causes frequent rebuilds during development. For example, adding a
commit that changes only CRefine would cause a change in the git-id
file, which would in turn trigger a rebuild of ASpec and everything that
depends on it. Because the git-id file also noted uncommitted changes,
these would also trigger an ASpec rebuild. Similarly, switching to a
different L4V_ARCH would cause the ARCH file to change, also triggering
an ASpec rebuild.
Since Isabelle makes it difficult to include this information in the
document without adding these files to the ROOT file, this commit is
removing this information until we find a better way.
Removes files that were duplicated in cspec/$L4V_ARCH directories to exist directly in
the cspec directory and contain $L4V_ARCH switches where needed. This allows for a single
Makefile for building the C kernel and the KernelInc_C theory, which is different between
architectures, to still exist per L4V_ARCH.
As the build location of the C kernel, and the resulting kernel_all.c_pp artifact, is
moved this change needs to be reflected in all the theory files that refer to it.
The seL4 kernel now supports a CMake based build in addition to the original Make based
one. This changes the Makefile that previously included the kernel Makefile to instead
have rules for instantiating a sub CMake build
As the location of built files have changed the KernelInc_C theory also needs to be updated
to point to the new locations for the generated artifacts.
