Changes during post-3.3/pre-3.4 development refactored storage of most
configure-time information, including variable bindings and function
scopes. All scopes (even short-lived) were kept persistently for
possible future debugging features, causing huge accumulated memory
usage. This was mostly addressed by commit v3.4.1~4^2 (cmState: Avoid
accumulating snapshot storage for short-lived scopes, 2015-11-24).
Since then we still keep short-lived scopes when they are needed for a
backtrace. This is because since commit v3.4.0-rc1~378^2
(cmListFileBacktrace: Implement in terms of cmState::Snapshot,
2015-05-29) backtraces have been lightweight objects that simply point
into the snapshot tree. While the intention of this approach was to
avoid duplicating the call stack file path strings, the cost turned out
to be holding on to the entire call stack worth of scope snapshots,
which is much worse.
Furthermore, since commit v3.4.0-rc2~1^2 (cmIfCommand: Issue CMP0054
warning with appropriate context, 2015-10-20) all conditions used in
`if()` commands hold a backtrace for use in diagnostic messages. Even
though the backtrace is short-lived it still causes the scope snapshot
to be kept. This means that code like
function(foo)
if(0)
endif()
endfunction()
foreach(i RANGE 1000000)
foo()
endforeach()
accumulates storage for the function call scope snapshots.
Fix this by partially reverting commit v3.4.0-rc1~378^2 and saving the
entire call stack during cmListFileBacktrace construction. This way
we can avoid keeping short-lived scope snapshot storage in all cases.
In commit v2.8.4~32^2~14 (Use cmake::IssueMessage for warnings,
2010-12-07) these warnings became formatted. It is more informative to
give the full call stack with such warnings. Also it is easier to
implement warnings with a full call stack because we do not have to
construct a custom backtrace with only the top.
This method was added by commit v3.4.0-rc1~424^2~6 (cmLocalGenerator:
Add IssueMessage method, 2015-06-13) in order to reduce callers'
dependency on cmMakefile. Currently the implementation of
cmLocalGenerator::IssueMessage is just a copy of the post-configure code
path in cmMakefile::IssueMessage. De-duplicate the implementation by
simply calling the cmMakefile copy for now. This will simplify upcoming
refactoring of backtraces. The dependency on cmMakefile can be removed
by future work once that is done.
Create a <LANG>_CLANG_TIDY target property (initialized by a
CMAKE_<LANG>_CLANG_TIDY variable) to specify a clang-tidy command line
to be run along with the compiler.
In the `try_compile` source file signature we propagate the caller's
value of `CMAKE_<LANG>_FLAGS` into the test project. Extend this to
propagate `CMAKE_<LANG>_FLAGS_<CONFIG>` too instead of always using the
default value in the test project. This will be useful, for example, to
allow the MSVC runtime library to be changed (e.g. `-MDd` => `-MTd`).
7731e44f Ninja: Honor CMAKE_NINJA_FORCE_RESPONSE_FILE for compile rules
f9644a2d cmGlobalNinjaGenerator: Clarify logic for forcing use of response files
24c9106b cmNinjaTargetGenerator: Factor out helper for forced response file check
The change in commit v3.5.0-rc1~198^2 (Ninja: Always re-run custom
commands that have symbolic dependencies, 2015-11-19) broke the
byproducts feature added by commit v3.2.0-rc1~340^2~2 (Add an option for
explicit BYPRODUCTS of custom commands, 2014-11-13) when SYMBOLIC
outputs also appear. This case occurs with AUTORCC-generated custom
targets because the output is SYMBOLIC (to always run) and the generated
file is a byproduct (for restat so dependents do not run unnecessarily).
The two use cases conflict because Ninja does not support per-output
restat. Favor restat whenever byproducts are present because it is
required for byproducts to work correctly. In use cases where we want
an always-run chain we simply will not be able to also use byproducts.
Fix logic introduced by commit v3.5.0-rc1~198^2 (Ninja: Always re-run
custom commands that have symbolic dependencies, 2015-11-19) to not
consider only the last output. We need to know if any output is
SYMBOLIC, so stop checking as soon as one is found.
Since commit v3.5.0-rc1~241^2~1 (cmFortranParser: Parse #line
directives, 2015-11-02) our Fortran dependency scanner parses `#line`
directives to extract the named files. However, some compilers produce
`#line` directives that name directories instead of files. Work around
such cases by verifying that the extracted path names a file and not a
directory.

06b310b5 cmCTestGIT: add an option to initialize submodules on update
56c1ea40 cmCTestGIT: fix git version references
Currently, CTest will not initialize any submodules within the already
checked out source tree. Add an option to do so. The use case for not
doing so is that some submodules may not be necessary for the current
test and keeping network usage down may be important.
Rename methods:
* `cmMakefile::Find{ => LocalNonAlias}Target`
* `cmLocalGenerator::Find{ => LocalNonAlias}GeneratorTarget`
These names clarify that they are for directory-local target names
and do not consider alias targets.
Refactoring in commit v3.5.0-rc1~272^2~11 (cmTarget: Implement ALIAS in
terms of name mapping, 2015-10-25) accidentally introduced logic that
assumes ALIAS targets always reference targets in their own directory.
Fix this and add a test case.
The configure-step fix is that `cmMakefile::FindTarget` should not consider
aliases. The purpose of this method is just to look up targets local to
a directory. Since ALIAS and normal targets share a namespace we know a
locally defined target will never collide with an ALIAS target anyway.
The method has 3 call sites, and this change is safe for all of them:
* `cmInstallCommand::HandleTargetsMode`: Rejects aliases before the call.
* `cmFLTKWrapUICommand::FinalPass`: Should never have considered aliases.
* `cmMakefile::FindTargetToUse`: Falls back to a global lookup anyway.
The generate-step fix is that `cmLocalGenerator::FindGeneratorTarget`
should not consider aliases. This method is the generate-step
equivalent to the above. The method has 2 call sites, and this change
is safe for both of them:
* `cmInstallTargetGenerator::Compute`: Never uses an alias target name.
* `cmLocalGenerator::FindGeneratorTargetToUse`: Falls back to global lookup.

Calls to `IsKeyword("...")` cause runtime construction of std::string.
Avoid possible repeated allocation by pre-allocating keyword strings
during initialization.
In commit v3.4.0-rc2~1^2 (cmIfCommand: Issue CMP0054 warning with
appropriate context, 2015-10-20) we added construction of a
cmListFileContext with conversion of the calling file path. This code
path runs on every condition (e.g. `if()`) and so the path conversion
has a noticeable performance cost. Fortunately the only use of this
context is for insertion into cmMakefile::CMP0054ReportedIds so we do
not need to convert the path. Simply drop the conversion.

Re-lookup a variable value when an associated VariableWatch is executed
in cmMakefile::GetDefinition.
This fixes a problem with 'def' sometimes becoming invalid due to memory
reallocation inside an std::vector. In this case, the problem was that
if the call to VariableAccessed actually executed a callback function,
the internal state of the makefile has changed due to the associated
function scope being pushed. This in turn implies that a new
cmDefinitions instance was pushed in cmMakefile::VarTree. As
cmLinkedTree is based on an std::vector, this push can have triggered
reallocation of its internal memory buffer. However, as the value of
'def', which was computed on method entry, actually points to a property
of one of the cmDefinitions instances in cmMakefile::VarTree,
reallocation can invalidate the value of 'def' so that it cannot simply
be returned at the end of the function. The solution implemented here is
to simply lookup the value of 'def' again.
This commit fixes a bug in the implementation of the test property
TIMEOUT_AFTER_MATCH. The new timeout value was being applied
every time a line was output by the test after the match had been
encountered. Now the new timeout value is only set once.
This commit also improves some output formatting related to this
property.

Some compilers on OS X report errors in the CoreServices framework headers.
Check for support of the header ahead of time and compile the relevant code
only when the header is available.
With the Makefile generator one can use `cd $subdir; make all` to build
all targets associated with a given subdirectory. This is not possible
to do with the Ninja generator since there is only one `build.ninja`
file at the top of the build tree. However, we can approximate it by
allowing one to run `ninja $subdir/all` at the top of the tree to build
the targets in the corresponding subdirectory.
Port logic from cmGlobalUnixMakefileGenerator3::WriteDirectoryRule2 to
cmGlobalNinjaGenerator in order to produce equivalent directory-level
targets.
In commit v3.5.0-rc1~232^2 (CPackDMG: Add support for multilingual SLAs,

to its APIs to convert Script Manager RegionCode values. This is not
necessary. Instead we can use CoreServices.
While at it, replace individual CoreFoundation includes with including
the entire framework, which is the correct way.

in `DeploymentTool` and the `RemoteExecutable` in `DebuggerTool`.
Use a `DEPLOYMENT_REMOTE_DIRECTORY` target property to specify the

Calling `project()` or `enable_language()` from a toolchain file will
infinitely recurse since those commands load the toolchain file.
Diagnose and reject this case with an error message instead of crashing

Since commit v3.4.2~2^2 (VS: Fix VS 2015 .vcxproj file value for
GenerateDebugInformation, 2016-01-08) we generate invalid project
files for the v110 and v120 toolsets. VS complains:

error MSB4030: "Debug" is an invalid value for the "GenerateDebugInformation" parameter of
the "Link" task. The "GenerateDebugInformation" parameter is of type "System.Boolean".
This reveals that our VS flag map selection should be based on the
toolset instead of the version of VS. However, that will be a
non-trivial change so for now fix this particular use case by
hard-coding a correction to the flag map.

When performing some other testing, the globs for Blanket.js and Delphi
code coverage are picking up unintended files. Change the query for the
Delphi coverage to follow the naming convention, and check the second line
of the found JSON files for certain text before parsing them as coverage files.
Although we fail with an error on a hash mismatch, it is not a fatal
error so the script may continue processing. If the download itself had
no error then report in the STATUS variable that the operation was not

With this patch, the builtin macros and include dirs are only
added to the project file if the C/CXX langauges are really enabled.
I.e. before this patch the CXX-stuff was in the project file as soon
as CXX had been enabled at least once for this build tree.
I.e. disabling CXX later on did not remove the CXX macros etc.

Create a `CMAKE_TRY_COMPILE_TARGET_TYPE` option to specify use

This will be useful for cross-compiling toolchains that cannot
