Stephen Kelly 5181fae264 cmPropertyMap: Remove chaining logic.
The chaining logic doesn't belong to the container, and the
CMakeInstance pointer doesn't need to be in cmPropertyMap.

Size goes from 56 to 48 bytes with GNU libstdc++-5.1.

Stephen Kelly 4e5c70abe2 cmState: Extract a cmLinkedTree container adaptor.
This will be used to contain most of the content of the cmState
in several different trees.  Refer to the BuildsystemDirectory
state from the SnapshotData state.  Currently these trees have
the same structure, but that will change when we have more snapshot
types.

Stephen Kelly 7b9c75860d cmState: Group BuildsystemDirectory state together in a struct.
It needs to be snapshotted independently of other state.

Stephen Kelly 3b880a0741 cmLocalGenerator: Require a valid cmState::Snapshot in the ctor.
Refactor the local generator creation API to accept a
cmState::Snapshot.  Adjust MakeLocalGenerator to use the 'current'
snapshot in cases where there is no parent.  Create the snapshot
for subdirectories in cmMakefile::AddSubdirectory.

This means that snapshots are now created at the point of extending the tree,
as appropriate, and independently of the cmLocalGenerator and cmMakefile they
represent the state for.

Stephen Kelly 01e1cd5c1f cmState: Move snapshot creation to the cmake instance.
Don't create a snapshot in Initialize(), but leave the creation
responsibility to the cmake instance instead.  Previously, the
cmState would Initialize() in its constructor, and the cmake instance
would re-Initialize() during Configure().  The end result was the
same and there would be one snapshot present.  However, cmLocalGenerator
also created a snapshot on construction, and that one was used, leaving
the first snapshot unused, and potential for off-by-one errors.

Fix that by making the cmLocalGenerator use the existing snapshot
if it is top-level.  Add a CurrentSnapshot to the cmake instance and
populated it while configuring a directory.  This will eventually
replace the 'current local generator' concept.  Fix the GetParent
implementation to be able to return the first snapshot.

Stephen Kelly 991f5e4968 cmState::Snapshot: Store components for current directories.
Remove this responsibility from cmLocalGenerator.

Stephen Kelly 57bdc1a2f7 cmState: Compute and store directory components.
There is no need to duplicate these in all cmLocalGenerators.

Rename the symbols according to current conventions.

Add explicit calls to Set{Source,Binary}Directory with empty strings
in order to trigger the population of the components containers with
the current working directory in cmLocalGenerator.  Having
directories set to empty is a special case in CMake, which is relied
on for the `if(CMAKE_BINARY_DIR)` condition at the end of
CMakeDetermineSystem.cmake.

Stephen Kelly 48a9e91b02 cmState: Add an accessor for Parent snapshot and a validity check. 2015-05-14 20:36:28 +02:00
Stephen Kelly 83dc483e4e cmState: Truncate snapshot data in Initialize.
When Configure is executed multiple times with the same cmake
instance (either using CTest --two-config or a interactive gui), the
location and structural data was preserved though it would not be used
again.  Fix that by clearing the data in a method called early in
the configure step.

Brad King 27343e3b68 cmGlobalGenerator: Finish storing enabled languages in cmState
In commit 74de9a73 (cmGlobalGenerator: Delegate storage of enabled
languages to cmState, 2015-04-11) the original LanguageEnabled
member of cmGlobalGenerator was left behind by mistake.  One use
of it in EnableLanguagesFromGenerator (for try_compile) was left,
but the member is not populated anymore.  Drop the member and
teach EnableLanguagesFromGenerator to copy the list of enabled
languages from one cmState to the other.

Stephen Kelly 3a041c5949 Introduce cmState::Snapshot.

This class will be extended in follow up commits to snapshot
all values in the cmState.

Stephen Kelly a6b1ad1309 Introduce cmState class.
At this point, it is an interface to the cache.  It will be extended
to be a universal interface for access to and manipulation of
configuration-time data (defintions, properties on targets,
directories, source files etc).

This will allow porting all command implementations away
from the cmMakefile and cmTarget classes, and result in something
more-purely related to configuration-time processing of cmake
commands.  That should serve at least the following goals:

 * Split the CMake implementation more definitively into three
   stages: Configuration, computation and generation, and be able to
   implement each optimally for memory access patterns etc.
 * Make better IDE integration possible by making more configuration
   data available.
 * Make it possiblte to use a smaller library than CMakeLib.a in
   cpack and ctest, resulting in smaller executables.
 * Make it possible to run the configure step multiple times in
   the same CMake run (#14539).

Manage its lifetime in the cmake class, and add a convenience accessor
to cmMakefile.
