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.
The InitializeAutogenTarget creates new targets and adds them to the
Targets container on the makefile. In this method, we have a reference
to that container and we are iterating over it. That happens to work
with hash_map, but it fails with undefined behavior when using the
std::unordered_map from libstdc++-4.9 (and likely others).

...
If the CMakeLists.txt file does not exist, there must be a parent.
The case for the top-level of the project is already handled in
cmake::DoPreConfigureChecks.
The Borland generator re-implements every method the NMake generator
does, so there is no reason to inherit this way. Instead inherit
directly from cmGlobalUnixMakefileGenerator3 like all the other
makefile generators do.
KWSys upstream added an attribute to export .gitattributes so that
importing snapshots into the sources of other projects would bring along
the attributes. However, we don't want to export them from CMake.
Drop .gitattributes entries not relevant to CMake.
Teach the legacy two-argument signature to use CMAKE_CONFIG_TYPE
from the environment only if it is non-empty. This makes behavior
consistent with the main signature.
The find_package command, on Windows, has always searched build trees
recently visited by cmake-gui (or CMakeSetup at one time). This was
done when the command was created with the intention of simplifying
workflows involving building multiple dependent projects. However,
this behavior depends on recent developer interaction and therefore
can create different find results based on transient system states.
It can lead to surprising results and user confusion.
Since this behavior was first added CMake has gained many more search
options, better error messages when a package is not found, and a
package registry. The latter in particular allows projects to make
their build trees available for dependent projects to find without
user intervention. Therefore the originally intended workflow can
be achieved in other, more stable ways.
After the above evoluion of find_package we have now decided that
the magic search-where-cmake-gui-was behavior does more harm than
good. Drop it. We do not need a policy for this behavior change
because it only affects interactive use.
The GNU 4.8 standard library's cstdio header is not aware that C++14
honors C11's removal of "gets" from stdio.h and results in an error:
/.../include/c++/4.8/cstdio:120:11: error: no member named 'gets' in the global namespace
Detect this problematic case and default to using C++11 instead of
C++14 for building CMake itself.

957c2aac RC: Simplify selection of resource compiler based on C/C++ toolchain
Use the KWSys Process "MergeOutput" option to give the child process
the same pipe (or file) for both stdout and stderr. This allows
natural merging of stdout and stderr together instead of merging
on arbitrary buffered read boundaries as before.
Since commit v2.8.11~213^2 (Ninja: Avoid LNK1170 linker error, 2013-02-01)
we generate linker response files with "$in_newline" to support a large
number of object files with the MS link.exe tool. However, the GNU linker
on Windows does not understand the newline endings that Ninja puts in the
response files. Switch back to "$in" for that case.
Check for CMAKE_COMPILER_IS_MINGW only after enabling a language when it
might actually be set. Previously this worked by accident because the
check for working compiler or a second language enabled would cause the
code path to be taken.
Store UsingMinGW as an instance member of cmGlobalNinjaGenerator so that
it is reset on each reconfigure. Otherwise cmake-gui cannot switch
between build trees for MinGW or non-MinGW tools.
Revert the refactoring by commit v2.8.11~105^2~1 (Ninja: use MinGW
generator code in EnableLanguage, 2013-03-09) and move the MinGW-
specific logic back to the "MinGW Makefiles" generator. Instead teach
the platform information modules for GNU and MSVC on Windows to set the
preferred RC compiler just before enabling the RC language. This way
we choose the RC compiler based on the C/C++ toolchain that is actually
enabled.

Since commit 80909041 (cmMakefile: Disable copy constructor, 2015-04-18)
the only call to cmMakefile::Initialize is in one constructor. Inline
it and drop the separate method.
In commit 86f3cd0f (cmMakefile: Require the localGenerator in the
constructor, 2015-04-27) we added use of GetDefinition to the
Initialize method. Set SuppressWatches before calling this method
since GetDefinition checks it.
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.
For some reason, using recursion here is faster to configure ParaView
than using a loop. Probably some compiler optimization is inhibited
by using a loop.

When given the command line
tool a\ b c
mingw32-make incorrectly passes "a b" and "c" to the tool. When given
the command line
tool a\ b "c"
mingw32-make correctly passes "a\", "b", and "c" to the tool.
Since commit v3.1.0-rc1~861^2 (MSVC: Add properties to configure
compiler PDB files, 2014-02-24) we pass the compiler pdb option to
MS-style compiler tools as "/Fd<dir>\" but mingw32-make may consume
the backslash as escaping a following space as described above.
Workaround this problem by changing the backslash to a forward
slash as had been used prior to the above commit.

This reverts commit 242c3966 (add_custom_command: Diagnose
MAIN_DEPENDENCY limitation, 2015-03-09) and the follow up commit
b372a99a (UseSWIG: Do not use MAIN_DEPENDENCY on custom commands,
2015-03-26).
I misdiagnosed the underlying issue that prompted creation of policy CMP0057.
The actual issue surfaces when a single custom command's MAIN_DEPENDENCY
is listed in more than one target; this issue will have to be addressed
independently.
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.
Reported-by: Matt McCormick <matt.mccormick@kitware.com>
The purpose of the stack is to allow access only to the top of it. Access
to items which are not at the top is needed, so cmDefinitions objects
get a Parent pointer.
The existence of the Parent pointer is a workaround for the inappropriate
use of stack in the first place. Remove it now.
Construct the final list directly in a named return value. Use
a single set to track bindings already found.

Check that a non-optional file exists before attempting to include
it. This makes more sense than relying on an error case deeper
within cmListFileCache.
Use more reliable logic to detect if a path ends in ".framework". The
old logic added by commit v2.4.0~791 (add better support for framework
linking, 2005-12-26) did not account for paths not ending in it at all.
With a 9-character path the logic and "npos == -1" happens to make the
old check pass.
This is needed for 'mode_t', and on mingw-w64 in particular. We added
use of 'mode_t' in commit v3.2.0-rc1~421^2 (file(GENERATE): Use
