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.
Currently there are an optimal number of policies (64) such that
there are no wasted bits. When another policy is added, the
cmPolicyMap will grow from 40 bytes to 80, and occupy 45. By storing
all in a single bitset, we stay under the cache line size of 64 bytes
until there are 512 policies in a range.
The Convert methods never belonged to the local generator concept, so
split them out now. The cmOutputConverter is cheap to construct and
destroy, so it can be instantiated where needed to perform
conversions. This will allow further decoupling of cmLocalGenerator
from the configure step.
Inherit cmLocalGenerator from cmOutputConverter for the purpose of
source compatibility.
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.

17e13f0a cmMakefile: Simplify CMP0000 handling.
Compute deterministic GUIDs that are unique to the build tree by
hashing the path to the build tree with the GUID logical name.
Avoid storing them in the cache, but honor any found there.
This will allow project GUIDs to be reproduced in a fresh build
tree so long as its path is the same as the original, which may
be useful for incremental builds.
The test for this variable was removed in commit v2.8.8~330^2~7 (complex:
Remove ancient unused ComplexRelativePaths test, 2011-12-23).
Commit v3.1.0-rc1~425^2~2 (backtrace: Convert to local paths in
IssueMessage, 2014-03-12) appears to have accidentally made some backtraces
print relative paths with the variable because conversions which used to be
done at configure time, before the variable had an effect are now potentially
done at generate time.
The documentation of the variable says not to use it, and the docs are wrong in
that the variable actually applies in per-directory scope.
The read of the variable makes it harder to split conversion methods from
cmLocalGenerator where they don't belong. Remove it now.
Use the KWSys Process "MergeOutput" option to give each test child
process the same pipe for both stdout and stderr. This allows natural
merging of stdout and stderr together instead of merging on arbitrary
buffered read boundaries as before.
Currently cmMakefile calls MakeRelative on a copy of the backtrace,
emits the copy to the stream once, then discards the copy. There
is no need to have API for the path conversion.
Teach cmFileCommandCurlDebugCallback to filter the debug data by type
and show only summary information instead of the raw data. This avoids
allocating memory for all data transferred by UPLOAD or DOWNLOAD.
The chunkDebug buffer we use to accumulate the LOG variable content
is populated if and only if a log variable was requested by the call,
but it is much clearer to check that a log variable was requested
explicitly before populating it.
Remove debugging logic left from commit v2.6.0~305 (add DOWNLOAD option
to FILE command, 2008-02-06). The CURLE_OPERATION_TIMEOUTED code path
does nothing that the code immediately after it does not do.

The regex update in commit v3.1.2~4^2 (ctest_build: Update GNU make
error message matching, 2015-01-28) broke matching of the messages it
updated. Remove the escape character before the square brackets added
by that commit.
3b880a07 cmLocalGenerator: Require a valid cmState::Snapshot in the ctor.
e12afe76 cmState: Host some state from the cmGlobalGenerator.
c7b79aa1 cmGlobalGenerator: Require a cmake instance in ctor.
01e1cd5c cmState: Move snapshot creation to the cmake instance.
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.
The StartXML, EndXML, and AddSiteProperties overloads that take a stream
directly are no longer called anywhere. All clients hvae been ported to
cmXMLWriter. Drop the old overloads.
In commit a390de65 (Ninja: Generate separate compile and link rules for
each target, 2015-05-18) we removed the _RSP_FILE suffix from rule names
meant for targets that need to build with a .rsp file because we now use
per-target rules anyway. Remove this suffix from references to the rule
too.

The <LANG>_VISIBILITY_PRESET and VISIBILITY_INLINES_HIDDEN were first
merged in commit v2.8.12~322 (Merge topic 'VISIBILITY_PRESET-property',
2013-06-05) but worked only for shared libraries and executables with
exports. Prior to commit v3.0.0-rc1~581^2 (GenerateExportHeader:
Deprecate add_compiler_export_flags function., 2013-09-02) the
add_compiler_export_flags function was used to add visibility flags to
all targets.
The visibility flags are useful for sources in all target types because
they may be later linked into shared libraries or executables with
exports. Introduce policy CMP0063 to enable them for all target types
while preserving compatibility with existing projects that do not expect
this.
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.
The virtual methods are overrides not overloads, the constructor
is no longer a default variant, the destructor and GetCMakeInstance
comments add no value, only a typo.
The 'ctest --launch' command must be placed before the IWYU launcher on
the compiler command line. Extend the RunCMake.IncludeWhatYouUse test
to cover this case. The Ninja generator already does it correctly.
Drop the VS >= 7 generator's global Configurations member and instead
lookup configurations using cmMakefile::GetConfigurations where needed.
This avoids accumulating all CMAKE_CONFIGURATION_TYPES values ever
encountered by a project() or enable_language() command and allows
the final value to be used in each directory. We don't officially
support per-directory CMAKE_CONFIGURATION_TYPES values but we certainly
should not generate configurations not in the final value in the top
level directory.
This reverts commit f85db2f323.
Discussion by the QtCreator community at
https://bugreports.qt.io/browse/QTCREATORBUG-13695
raises concerns about this particular approach to working with CMake
projects using QtCreator. Also, the functionality and design of the QBS
extra generator was never discussed on the CMake mailing list or with
QtCreator developers. There may be better ways to make the two tools
work together.
In order to avoid committing to long-term support of this generator
prior to such discussion taking place, revert it from CMake for now.
We may restore this or use an alternative design based on results of
such discussion.

The QMacInstallDialog infrastructure no longer works on modern OS X
versions. Drop it and replace the dialog with a simple info box that
explains to the user how to run 'cmake-gui --install' to add symlinks.
Also suggest simply modifying the PATH.
This approach is similar to the Xcode 'xcode-select --install' method
of installing Xcode Command Line Tools.
On OS X add an "--install[=/path/to/bin]" option (defaulting to
/usr/bin) that installs symbolic links into the given directory.
This will help OS X users make the tools available on the command
line even when they sit inside a CMake.app bundle.
Always show the option with its argument separate in summary text.
State in the main documentation that the option and its argument can be
given together too.
In cmMakefile::PushScope, a copy of the closure of keys initialized
in the parent scope is made. In PopScope, essentially the same copy
is inserted back into the parent. That means a lot of duplication
of strings and a lot of string comparisons. None of it is needed,
because the cmDefinitions keys already provide a canonical
representation of what is initialized.
The removal of the separate container also makes the variable handling
code more easy to reason about in general.
Before this patch, configuring llvm uses 200 KiB for the VarInitStack.
Overall peak memory consumption goes from 35.5 MiB to 35.1 MiB.
Presumably the intention here is to attempt to optimize memory by not
storing what is not needed. However, all keys need to be tracked
anyway to implement initialization tracking, and this special case
gets in the way of simplifying the implementation of that.
This doesn't change any observable effects because values set
to 0 are considered not to exist by the cmDefinitions API.
Create a <LANG>_INCLUDE_WHAT_YOU_USE target property (initialized by a
CMAKE_<LANG>_INCLUDE_WHAT_YOU_USE variable) to specify an IWYU command
line to be run along with the compiler.
Add an internal "cmake -E __run_iwyu" mode to wrap the compiler call.
Run a given include-what-you-use command line with the compiler options
and report a warning if it finds anything. Then run the real compiler.

This option was once used by our OS X package installer to create
symlinks at install time. Since switching to the DragNDrop installer
we no longer use this option.
The backtrace will soon not be implemented in terms of a stack of
cmListFileContext objects. Keep the cmListFileContext in the API
for convenience for now.
The PushTLLCommandTrace method is called once per link item for a single
target_link_libraries command. Avoid storing copies of identical
execution contexts and rely on the uniqueness while printing output.
Our <LANG>_COMPILER and <LANG>_<TARGET_TYPE>_LINKER rule generation has
access to a specific cmTarget so the results may depend on it. Instead
generate separate rules for each target using an encoded target name.
In particular, this makes CTEST_USE_LAUNCHERS report proper target
information.
The lexical scope counting added by commit v3.2.0-rc1~332^2~1 (Track
nested loop levels in CMake language with a stack of counters,
2014-11-18) forgot to account for scopes popped by error messages about
unclosed scopes. Teach the error handler to pop the lexical scope it
reports as unclosed. Re-order the lexical scope RAII object to be
inside the variable scope RAII object scope so that the lexical scope
is fully closed before we check assertions about variable scopes.
Extend the RunCMake.Syntax test with a case covering this.
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.
