Because the 8bit string encoding in libarchive can be different than
the 8bit string encoding in CMake, change to call the wide version
of libarchive functions. They are different if CMake is configured
to use UTF-8 as the internal encoding.
Create helper functions for some libarchive calls to use wstring
internally on platforms supporting it.
Commit v2.8.11~310^2~1 (Keep track of INCLUDE_DIRECTORIES as a vector of
structs., 2012-11-19) added special case of INCLUDE_DIRECTORIES
for the purpose of origin-tracking of individual entries in the property. It
introduced a bug in that it returned an empty string instead of '0' in the
case that no includes have been set.
Commit v2.8.11~289^2~2 (Handle INTERFACE properties transitively for includes
and defines., 2012-09-23) introduced transitive handling of the property
through the link implementation, together with a whitelist of properties
which would be evaluated transitively. Because of the bug introduced
previously, the 'prop' in TargetPropertyNode is non-null,
meaning that the content (the empty string) would be evaluated as a generator
expression. This was harmless as the follow-up code was only for 'INTERFACE_'
variants of target properties, so the effect was the same.
Commits v2.8.11~280^2~2 (Keep track of properties used to determine linker
libraries., 2012-11-05) and v2.8.11~280^2~1 (Add API to calculate
link-interface-dependent bool properties or error., 2013-01-06) added a way
to track and report errors on properties which both determine and are
determined by the link implementation. This was later used in generator
expression evaluation by commit v2.8.11~252^2~2 (Make INTERFACE determined
properties readable in generator expressions., 2013-01-19). If a property
is unset (null), and the link implementation of the target was not being
evaluated, this commit made it possible to evaluate the property from the
link implementation instead. If the link implementation was being evaluated,
an empty string was returned from the generator expression evaluation, which
might be later reported as an error.
The above logic was written for 'compatible interface' properties, but in
fact it should have also included other properties. Because of the
empty-string-instead-of-null bug, this code block is not entered for the
INCLUDE_DIRECTORIES property. At this point, however, the bug still does
not significantly affect behavior, because the follow-up code is still a
no-op for the INCLUDE_DIRECTORIES property, and an empty string is returned
regardless. Commit v2.8.11~189^2~6 (Use the link information as a source of
compile definitions and includes., 2013-02-12) refactored the logic, but also
without a change in behavior.
Commit v2.8.11~156^2~2 (Expand includes and defines transitively
in 'external' genexes., 2013-02-13) refactored the logic again, this time with
a change of behavior. The INCLUDE_DIRECTORIES property was then mapped to
INTERFACE_INCLUDE_DIRECTORIES during transitive generator expression
evaluation. Because the transitive evaluation involved evaluation of the
link implementation, this introduced a recursive loop and a segfault with
code like:
add_library(empty1 ...)
add_library(empty2 ...)
target_link_libraries(empty1
PRIVATE
$<$<STREQUAL:$<TARGET_PROPERTY:INCLUDE_DIRECTORIES>,/foo/bar>:empty2>
)
As there is no real use-case for reading a target property like that while
evaluating the link implementation, this went unnoticed. The same pattern
was followed for other special-cased reads of transitive target properties
such as COMPILE_DEFINITIONS.
The segfault was fixed in the parent commit, but change the property to
return null when appropriate for other future uses.
Commit v2.8.11~156^2~2 (Expand includes and defines transitively
in 'external' genexes., 2013-02-13) introduced a recursive loop
and a stack overflow during evaluation of a link implementation
which depends on a transitive property, such as
add_library(empty1 ...)
add_library(empty2 ...)
target_link_libraries(empty1
PRIVATE
$<$<STREQUAL:$<TARGET_PROPERTY:INCLUDE_DIRECTORIES>,/foo/bar>:empty2>
)
There is no use-case for code like that currently, but it should not
cause a stack overflow.
Avoid the recursion by reporting an error early if a case like this
is found.
A library or executable target that consists only of a reference to an
object library may have no sources to compile or custom commands to run.
The command in the target is the link (or archive) command. Add missing
order-only dependencies to link commands so that target ordering
dependencies are satisfied for it without depending on an intermediate
compilation rule.
Extend the ObjectLibrary test to cover this case.

Ninja generator ensures that all custom commands being target
dependencies are run before other source compilations. However in case
there are no such dependencies it currently generates empty phony rules
which clutter the build graph.
Teach the Ninja generator to produce such rules only when necessary.
Actually custom command can write wherever it wants to, such as temporary
folder or source folder, possibly violating rules that only build folder should
be affected. Therefore we should consider custom command dependency at any path
as possible side effect adding phony rule.
We avoid adding phony rules for regular source files (since the paraent
commit) so we no longer need the in-build-tree test to avoid them.
Since commit v2.8.12~248^2 (Ninja: Custom Command file depends don't
need to exist before building, 2013-06-07) all explicit dependencies
inside build folder were considered as possible build command
side-effects and phony rules were produced for them in case they don't
exist when starting to build. This is unnecessary since regular compile
inputs need to exist or cmake will fail. Moreover the exception for
sources having GENERATED property that can be missing is already handled
by WriteAssumedSourceDependencies.
This fixes unwanted phony rules for all regular source files when doing
in-source build, causing Ninja not complain when such files gets missing,
i.e. during development. Also this reduces number of rules in ninja.build.
Now only custom command dependencies are considered as possible side-effects.

The ctest launcher code did not respect the number of errors and
warnings limits. Limit the number of launcher report fragments that we
report in the final submission.
Use LinkImplementationPropertyEntries directly instead of asking
GetProperty to construct a string for LINK_LIBRARIES. This gives us
access to the entry backtraces.
If ComputeLinkImplementationLanguages were ever to cause
GetLinkImplementationLibraries to be invoked then a LinkImplMap entry
may appear in the middle of computing it in GetLinkInformation. Instead
create the map entry up front and store in it boolean values indicating
which pieces of the LinkImplementation structure have been populated.
This approach leads to shorter code that is easier to follow too.
Members of the cmTargetInternals structure do not need to be made
'mutable' even to cache data because there is no reason for the
internal methods to be 'const'.
Teach GetTransitivePropertyTargets to use the GetLinkInterfaceLibraries
method with usage_requirements_only==true instead of evaluating the
INTERFACE_LINK_LIBRARIES property directly. This avoids duplicate
evaluations and makes use of the caching done by
GetLinkInterfaceLibraries.
Add a 'usage_requirements_only' parameter to GetLinkInterfaceLibraries
and supporting internal APIs to pass through to ExpandLinkItems so it
knows whether to use SetTransitivePropertiesOnly while evaluating
generator expressions.
Simplify the implementation of GetTransitivePropertyTargets by using
ExpandLinkItems with usage_requirements_only==true to evaluate the
generator expressions in the link interface for us.
Add a 'usage_requirements_only' parameter to ExpandLinkItems so that it

generator expressions. Update existing call sites to pass 'false' since
they are for linking and not usage requirements.
Since commit 6557382d (stringapi: Use strings for program

From the GCC 4.9 release notes for Fortran:
https://gcc.gnu.org/gcc-4.9/changes.html
"Module files: The version of the module files (.mod) has been
incremented; additionally, module files are now compressed."
Teach cmDependsFortran::ModulesDiffer to look for the gzip magic numbers
at the beginning of the module file. If found, assume the module was
produced by gfortran >= 4.9. The modules do not appear to contain the
date as earlier versions did so we can compare the content directly
and do not actually need to decompress.
Since commit 84fdc9921 (stringapi: Pass configuration names as strings,
2014-02-09), it is not safe to use GetDefinition("CMAKE_BUILD_TYPE")
without checking the return value. Use GetSafeDefinition instead so
that a missing definition is treated as an empty string like code paths
did prior to the above commit.

Use GetLinkImplementationLibraries instead of GetDirectLinkLibraries
because it tells us whether there will be any libraries to link after
evaluating generator expressions. Also GetDirectLinkLibraries will be
dropped soon.
Instead of storing just the string names in these structures, lookup any
target associated with each item and store its cmTarget pointer. Use
the cmLinkItem class to hold the name and pointer together. Update
client sites to use the pre-stored lookup result instead of looking up
the target name again.
Create a cmTarget::LookupLinkItems helper method to handle the lookup.
Since lookups are now moving from cmComputeLinkDepends::AddLinkEntries
to cmTarget::LookupLinkItems, move use of CheckCMP0004 to the latter.
This drops use of CheckCMP0004 from entries added for _LIB_DEPENDS
variables by cmComputeLinkDepends::AddVarLinkEntries, but I do not
think that use was intentional originally anyway.
Add a method like GetUtilities but that provides the target names
already looked up and resolved to cmTarget pointers internally. Update
call site in cmComputeTargetDepends::AddTargetDepend to use the
already-found target instead of looking it up again.
Many items named in target_link_libraries calls are targets, but not
all. Create a cmLinkItem type that acts like std::string so it can name
an item but also has a pointer to a cmTarget that is the result of
looking up the item name in the referencing target's scope. This will
be useful to avoid duplicate lookup operations later.
In cmTarget, cmGeneratorTarget, and cmGeneratorExpressionEvaluator, fix
target name lookups to occur in the cmMakefile context of the target
that referenced the name, not the current 'head' target. The context
matters for imported targets because they are directory-scoped instead
of globally unique. We already do this in cmComputeLinkDepends and
cmComputeTargetDepends.
Extend the InterfaceLibrary test with an example covering this behavior.
Move generator expression evaluation for imported library lists out of
GetImportInfo and into a new GetImportLinkInterface helper. This avoids
duplicating the computation and storage of all imported target info just
because some of it is parameterized on the 'head' target.
Many of the 'head' arguments added by commit v2.8.11~289^2~1 (Make
linking APIs aware of 'head' target, 2013-01-04) turned out not to be
needed. The "link implementation" of a target never needs to be
computed with anything but itself as the 'head' target (except for
CMP0022 OLD behavior because then it is the link interface).
Remove the unused 'head' target paths. Add "internal" versions of
cmTarget::GetDirectLinkLibraries and GetLinkImplementationLibraries
to support the CMP0022 OLD behavior without otherwise exposing the
'head' target option of these methods.
Create an ExpandLinkItems method to handle evaluation of generator
expressions in a library list and expansion of the ;-list into a vector.
Replace some duplicate copies of the implementation with calls to the
new helper.

It may happen that CMake include is an explicit dependency for some command,

lead to duplicate phony generate rules which causes ninja warnings.
We need to remove implicit CMake includes in WriteUnknownExplicitDependencies.
This fixes FindCUDA ninja warnings.
For testing purposes CMake creates dummy memory checkers. The dummy checkers
are in the CMake build tree. Before this change when the path contained the
string valgrind, such as CMake-valgrind, all the checkers were thought to
be valgrind, and this caused tests to fail.
Instead printing complete help cmake/ccmake now prints only Usage section and
extra information how to get more help or start your build.
Implementation Details:
Usage help type was renamed to Help, and new Usage was introduces that prints
only command line usage information without any extra details.
Commands add some extra information when no arguments are passed.

Since commit v2.8.12~300^2~1 (CLI: Suppress the unused warning if the
key value pair is cached, 2013-05-16), cmake::SetCacheArgs saves a
cachedValue pointer and may cause the memory to be freed (by setting the
cache entry) before reading it again. Fix this by saving the old value
in a separate string.
Each project listed in a .sln must be marked (or not) as part of the
"default build" for each configuration. For targets created by the
add_custom_target() command we add them to the default build if they
are not excluded in some way or if another target depends on them.
In the top-level .sln, a custom target is excluded if it is not
created with the ALL option to add_custom_target. In subdirectory
.sln files, a target may also be excluded if it is not within the
directory and is brought into the solution only due to a dependency
from another target in the solution.
Fix the "IsPartOfDefaultBuild" and "IsDependedOn" methods to check
every target to be included in the .sln for a dependency on the
custom target. Otherwise transitive dependencies through targets
not in the current subdirectory will not be considered.
Extend the SubProject test with a custom target to cover this case.

currently used to lookup the flag table for each tool into class
methods. This avoids passing the this->LocalGenerator member and

Create a Platform/Android module that includes Platform/Linux since
Android is based on Linux. Provide only the minimal settings needed to
get builds with Android NDK toolchains to work.
Disable use of RPATH since the Android loader ignores it and we cannot

Android supports soname but shared library names must end in ".so" and
we cannot represent the versioned names with associated symlinks on all
host operating systems anyway. However, we do want the SONAME of
library files to be set so that linking to them by path to the library
file produces NEEDED entries with the soname and not the path. Add a
new CMAKE_PLATFORM_NO_VERSIONED_SONAME setting to tell the
cmTarget::GetLibraryNames method that not to use the VERSION or
SOVERSION target properties in the soname.
In commit 84fdc992 (stringapi: Pass configuration names as strings,

Fix them now.
Some compilers do not offer an option to specify the path to the object
file, but rather only to the directory in which to place the object
file. See issue 14876 for some examples. Add a new OBJECT_FILE_DIR
placeholder to specify the directory containing the object file for the
current compilation. This may differ from the main target OBJECT_DIR
when the object corresponds to a source in a subdirectory.
Delay use of CMAKE_GENERATOR_TOOLSET until the CMakeSystem.cmake
file has been configured and loaded during the first project() or
enable_language() command. This gives the toolchain file named by
CMAKE_TOOLCHAIN_FILE a chance to set CMAKE_GENERATOR_TOOLSET. This
point is still early enough to set the generator toolset prior to
the initialization of any languages that might use the toolset.
The cmake::GeneratorToolset member variable remains an indication
of what was specified by the -T option or loaded from the cache.
It does not need to be updated based on the toolchain file setting.
The cmMakefile::TryCompile can still pass cmake::GeneratorToolset
into the inner instance because the try-compiled project will do
platform and language initialization using the CMakeSystem module
configured for the outer project.
Extend the RunCMake.GeneratorToolset test with cases that use a
toolchain file to set CMAKE_GENERATOR_TOOLSET.
Divide the cmGlobalVisualStudio10Generator "PlatformToolset" member into

The VS 7-9 IDEs parse .vcproj file boolean values in lower or upper
case. The .NET XML parsing chokes on anything but "true", "false", "0",

While tracing dependencies of a target, cmTargetTraceDependencies
follows sources by full path to determine if the source is to be
produced by a custom command. Commit 4959f341 (cmSourceFileLocation:
Collapse full path for directory comparisons., 2014-03-27) changed
the storage of target sources to be in the form of a normalized
path instead of an unnormalized path.
The path is followed by looking it up in a mapping via
cmMakefile::GetSourceFileWithOutput to acquire an appropriate
cmSourceFile. The mapping is populated with the OUTPUT components
of add_custom_command invocations, however it is populated with
unnormalized paths. This means that the tracing logic does not
find appropriate cmSourceFiles, and does not generate appropriate
build rules for the generated sources.
Normalize the paths in the OUTPUT components of add_custom_command
to resolve this.
The paths in the DEPENDS component of add_custom_command are also
not normalized, leading to the same problem again. Normalize the
depends paths after generator evaluation and expansion.
Teach set_property and get_property an "INSTALL" property type to be
associated with install-tree file paths. Make the properties available
to CPack for use during packaging. Add a "prop_inst" Sphinx domain
object type for documentation of such properties.
If the coverage.py source file is not found in the source directory, the
build directory is first searched before raising an error.
This is necessary because it is a valid workflow to build a Python
package from source, then install this package to a virtualenv that
lives in the build directory. Tests will run against this deployed
package and therefore the covered source files will be found in a
subdirectory of the build directory, and not anywhere in the source
directory.
Since commit bef93dc5 (Couple of changes: cache variables now have a map
of properties, 2002-09-11) the cmCacheManager::AddCacheDefinition method
accesses its map entry by reference. However, the commit left the
original entry assignment at the end of the method. With Apple Clang
5.1 and libc++ this self-assignment destroys the cache entry property
map.
Drop the self assignment. Also drop the condition around the call to
UnwatchUnusedCli since it was a self-comparison that must always have
been true.
Teach cmake::HandleDeleteCacheVariables to tolerate a missing HELPSTRING
(NULL pointer) when saving cache entries. In the absence of other bugs
this should not be possible, but avoid the crash just in case.
When CMP0053 is in WARN mode, variables get expanded twice, leaking the

40b9cd0f CMP0022: Fix link language propagation in NEW behavior
42bbf130 CMP0022: Fix link language propagation in NEW behavior
The languages used in compiling STATIC libraries need to be propagated
to dependents regardless of the settings of INTERFACE_LINK_LIBRARIES or
CMP0022. They are independent of the libraries in the link interface.
Prior to commit v2.8.12~192^2~2 (Introduce the INTERFACE_LINK_LIBRARIES
property, 2013-06-04) the cmTarget::ComputeLinkInterface code path for
"explicitLibraries" could never be taken for STATIC libraries, so the
logic to propagate languages existed only in the non-explicitLibraries
code path. After that commit, INTERFACE_LINK_LIBRARIES could be set for
STATIC libraries to cause the "explicitLibraries" code path to be taken.
The commit also left the old non-explicitLibraries code path conditional
on CMP0022 not being set to NEW. Thus link language propagation was
left missing from two cases by that commit.
The explicitLibraries code path was fixed to propagate languages by
commit v2.8.12~149^2~1 (cmTarget: Fix iface libraries and languages for
static libraries, 2013-07-26). However, the non-explicitLibraries case
was never taught to propagate languages when CMP0022 is set to NEW. Fix
that now. Factor the logic to propagate link languages out of the link
interface libraries conditions so that it always occurs. Update
Tests/Fortran to set CMP0022 to NEW to test this case (because the test
passes only if link language propagation works).

Fix the MUMPS coverage parser:
* Account for tabs after entry points
* Stop double incrementing lines that have explicit calls to the 0 line
* If a line has been previously marked as non executable, but then
contains a count, increment it an extra one to push it back into
the executable code set.
Add a custom routine and corresponding coverage files in the test case.
This file is smaller and has cmcov/mcov files that have data for only
that routine.
Add source file properties to control Xcode file type attributes:
XCODE_EXPLICIT_FILE_TYPE => explicitFileType
XCODE_LAST_KNOWN_FILE_TYPE => lastKnownFileType
Add a RunCMake.XcodeProject test to verify generated project content.
Choose the attribute name and file type and send them through a single
attribute generation code path. Compute the file extension only when
needed. Leave the file type selection logic indented in a block so it
can be made conditional later.
Output sent through these APIs is logically part of the CMake process
output. Capture it with callbacks and display it in the cmake-gui
output window along with other messages.
Factor a common callback type out of StdoutCallback. Add an equivalent
StderrCallback. While at it, use "size_t" for the data length instead
of "int".
Teach "ctest --build-and-test" to capture the Stderr callback because
output sent through it is part of the logical CMake process output.
Add properties and variables corresponding to CXX equivalents.
Add features for c_function_prototypes (C90), c_restrict (C99),
c_variadic_macros (C99) and c_static_assert (C11). This feature
set can be extended later.
Add a <PREFIX>_RESTRICT symbol define to WriteCompilerDetectionHeader
to conditionally represent the c_restrict feature.
Add ERROR_SHARING_VIOLATION to the set of errors (previously including
only ERROR_ACCESS_DENIED) that cause a rename (MoveFile) on Windows to
retry. The condition was observed when two renames to the same target
file name were happening simultaneously.

Since commit v3.0.0-rc1~305^2 (Ninja: deptype msvc for Intel's compiler
on Windows, 2013-11-25) we used "deps = msvc" for the Intel compiler.
This is correct only on Windows. On Linux we still want "deps = gcc".
Fix the logic to use "deps = msvc" when the compiler id or the "simulate
id" is "MSVC". This will preserve the behavior on Intel for Windows and
fix the behavior on Intel for Linux. In the future this should be
converted to a platform information module variable.
These policies should be checked at the call site that tries to access
the LOCATION or SOURCES property, not the directory scope containing the
target. Thread the caller context through cmTarget::GetProperty to use
for checking the policy setting and emitting a diagnostic with proper
backtrace.

cross-directory cases.

Use the CPack DragNDrop generator instead of the deprecated PackageMaker
tool to package CMake itself. This provides an installation experience
that is more consistent with other products on OS X and allows users to
select the destination directory easily. It also avoids installing
"/private/var/db/receipts/com.Kitware.CMake.*" receipts that must be
removed by "pkgutil --forget com.Kitware.CMake" before another version
of CMake can be installed.
The DragNDrop installer does not support a post-flight script, so drop
our configuration of it. The cmake-gui has an option for installing
symbolic links to enable command-line use. In practice users may simply
add "/Applications/CMake.app/Contents/bin" to their PATH instead.
Introduce a new implementation of ExpandVariablesInString and select
between the old and new implementations based on policy CMP0053.
Instead of cmCommandArgumentParserHelper, use a custom parser with our
own stack. This is much faster and works well for our simple grammar.
The new behavior of CMP0053 should expand @VAR@ syntax only in certain
contexts. All existing EVIS callers use "replaceAt == true" so
hard-code our call to the old implementation. Update the signature to
default to "replaceAt == false" and pass "replaceAt == true" explicitly
in the call sites for configure_file and string(CONFIGURE).
Testing the configure (no generate) step with ParaView shows ~20%
performance improvement.
In terms of complete configure/generate steps, further testing with
ParaView shows a 20% performance improvement over 2.8.12.2 with Unix
Makefiles and minimal with Ninja. Ninja is less because it generate step
is the expensive part (future work will address this) by a long shot and
these changes help the configure step for the most part.

This reduces ninja file output even more for projects with lots of
libraries with entangled transitive dependencies. ParaView goes from the
previous 58M to about 45M.
If creation of the global generator fails, return early with an error

Just like -I flag has its -isystem counterpart which marks an include
directory as a system directory and prevents unwanted warnings, on Apple
systems there is -iframework -- a system directory replacement for -F.
Use this flag to implement include_directories(SYSTEM) for frameworks.
Use the highest standard compile flags available if requested language
version is too new.
This supports use-cases like
set(CMAKE_CXX_STANDARD 14)
# Compiled with -std=c++11 with GNU 4.7, which has no -std=c++14
# or equivalent flag
add_executable(main main.cpp)
This can be used in combination with preprocessor defines which
communicate the availability of certain language features for
optional use.
Commit b8af2011 (cmTarget: Fix listing of source files at
configure-time., 2014-04-13) refactored a GetObjectLibrariesCMP0026
method out of GetLanguages. In flight, a conditional use of a target
if available was changed to an assert-available.
This code is only used to read the LOCATION property at configure
time, when the link information is incomplete, and not all targets
are defined, so the assert is inappropriate, even though it can lead
to incorrect information being generated. CMP0026 warns about the
potentially incorrect information anyway.
Include execinfo.h, cxxabi.h, and dlfcn.h under the same conditions
under which we use the APIs from them. Move their inclusion out of
OS-specific blocks.

ClearMatches was clearing many variables which were never set in the
first place. Instead, store how many matches were made last time and
only clear those. It is moved to the cmMakefile class since it is a
common utility used by multiple commands.
Create a Modules/CMakeSystemSpecificInitialize.cmake module loaded after
CMakeSystem.cmake but before per-language initialization. Use it to
load an optional Platform/<os>-Initialize.cmake module. This will be
useful to do per-platform initialization that does not depend on the
language and use the results when enabling specific languages.
The substr call was causing excess allocations. Swap the cheaper
character check to be before the longer string comparison, now using the
prefix checking function.
This option was removed during conversion to the reStructuredText
documentation. Restore it. Process documentation starting at
Help/index.rst so that all manuals are included in the output.
Fix cmOSXBundleGenerator::CreateCFBundle to place Info.plist under the
same root directory as the rest of the bundle. Without this, Info.plist
was placed into CMAKE_BINARY_DIR, not CMAKE_CURRENT_BINARY_DIR because
the target path was not generated correctly.

3b673586 CMP0052: Make the warning message more informative.
5baa8159 CMP0052: Test that include dirs in install locations cause no warnings.
9e0b3153 CMP0052: Do not warn when include dir is not in source or build tree
When the policy was added by commit 783bce29 (Export: Disallow exported
interface includes in src/build tree, 2014-03-31) it accidentally left a
code path that would warn when the include dir is in the install tree
but *not* in the source or build tree. Fix that.
As explained in cmVisualStudio10TargetGenerator::WriteSource comments,
VS tools append relative paths to the current directory, e.g.
c:\path\to\current\dir\..\..\..\relative\path\to\source.c
and fail if this is over 250 charaters or so. Previously we used a full
path only if no relative path could be constructed with a leading "../"
sequence that does not escape the source or build tree. This means that
long relative paths can be generated when the build tree is inside the
source tree, and can cause build failures due to the above path
concatenation problem.
Teach cmVisualStudio10TargetGenerator::ConvertPath to ask the Convert
method to honor CMAKE_USE_RELATIVE_PATHS. This will cause it to use
full paths by default but still give users the option of getting the
relative paths when possible.

OpenBSD defines Elf64_Dyn::d_tag to be of an unsigned type, which differs from
what most other platforms do and what is the case for 32 bit. To have the tag
as unsigned makes sense, but this causes a compilation warning:
/.../CMake/Source/cmELF.cxx: In member function 'const cmELF::StringEntry* cmELFInternalImpl<Types>::GetDynamicSectionString(int) [with Types = cmELFTypes64]':
/.../CMake/Source/cmELF.cxx:945: instantiated from here
/.../CMake/Source/cmELF.cxx:668: warning: comparison between signed and unsigned integer expressions
Add an explicit typedef to cast the value to for 32 and 64 bit. That type is
unsigned and has the proper length for both platforms so no information is
lost. Explicitely cast both arguments before comparing them to avoid the
warning in all situations.
The matches have already been calculated and can simply be taken from
CMAKE_MATCH_n variables. This avoids multiple compilations of the same or very
similar regular expressions.
Since commit e5da9e51 (cmTarget: Allow any generator expression in
SOURCES property., 2014-03-18), source files are computed by
true evaluation of generator expressions, including TARGET_OBJECTS.
This evaluation requires the presence of cmGeneratorTarget objects
since commit bf98cc25 (Genex: Evaluate TARGET_OBJECTS as a normal
expression., 2014-02-26).
Ensure that we don't attempt to evaluate the TARGET_OBJECTS generator
expression at configure-time, as can happen if CMP0024 or CMP0026
are OLD. Use old-style parsing of the source item to extract
object target names in that case.
Avoid calling GetProperty("SOURCES") to bypass warnings from CMP0051.
Refactor existing logic in GetLanguages which is similar in intent to
the new GetSourceFiles code.
Allow directories in the source tree or build tree only if the
install tree is a subdirectory of the source tree or build tree,
as appropriate.
Re-use the test files in the RunCMake.include_directories test
to run in multiple scenarios. Bump the required CMake version
in the test to 3.0 to ensure that the new policy warnings are
emitted correctly.
The AddSource method accepts one file and tries to avoiding adding
it to the sources-list of the target if it already exists. This
involves creating many cmSourceFileLocation objects for matching
on existing files, which is an expensive operation.
Avoid the searching algorithm by appending the new sources as one
group. Generate-time processing of source files will ensure
uniqueness.
Add a new AddTracedSources for this purpose. The existing
AddSources method must process the input for policy CMP0049, but
as these source filenames come from cmSourceFile::GetFullPath(),
we can forego that extra processing.
Computing the language involves computing the source files, which
is an expensive operation. It requires calling
cmMakefile::GetOrCreateSource many times, which involves creating
and matching on many cmSourceFileLocation objects.
Source files of a target may depend on the head-target and the
config as of commit e6971df6 (cmTarget: Make the source files depend
on the config., 2014-02-13). The results are cached for each context
as of commit c5b26f3b (cmTarget: Cache the cmSourceFiles in
GetSourceFiles., 2014-04-05).
Each target in the build graph causes language computation of all
of its dependents with itself as the head-target. This means that
for 'core' libraries on which everything depends, the source files
are computed once for every transitive target-level-dependee and
the result is not cached because the head-target is different. This
was observed in the VTK buildsystem.
Short circuit the computation for targets which have a source-list
that is independent of the head-target. If the source-list has
already been computed and the generator expression evaluation
reports that it was context-independent, return the only source-list
already cached for the target. Reset the short-circuit logic when
sources are added and when the link libraries are re-computed.
Follow up commit 1de08685 (cmSystemTools: Restore unreachable return to
silence warnings, 2014-04-02) by excluding the unreachable return on the
HP compiler as well as Clang. Both recognize that it is unreachable and
warn.
