Stephen Kelly dd043c3f21 Features: Add support for C++14 features.
Record the features implemented by GNU 4.9 and Clang 3.4.
2014-05-22 18:01:23 +02:00
Stephen Kelly e0890d03a4 Features: Extend concept to C language.
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.

Stephen Kelly a36b957fc4 Features: Add cxx_template_template_parameters.
Extend the existing feature infrastructure as needed to support
both C++11 and C++98 features.
2014-04-16 15:16:23 +02:00
Stephen Kelly f97bf4370c Features: Add cxx_auto_type.
Record the availability of this feature for GNU 4.8 on (UNIX AND
NOT APPLE) only.  In the future, availability can be recorded for
earlier GNU, for other platforms and for other compilers. Initially
the affected configurations are as restricted as possible to allow
for easy testing while extending the features vector in only one
dimension.

The error message when using the set_property API directly is not
very good, but follow up commits will provide origin debugging of
the property and a target_compile_features command which will
provide a configure-time backtrace when possible.

Stephen Kelly 8238a6cd5d Add some COMPILE_OPTIONS for specifying C++ dialect.
These are compiler-specific, compiler version specific, extension specific
and standard version specific.

Stephen Kelly 892243fc3b Tests: Require CMake 3.0 for the SystemInformation test.

Brad King cc676c3a08 OS X: Detect implicit linker framework search paths
Previously we hard-coded a list of implicit framework directories but
did not account for CMAKE_OSX_SYSROOT or for changes to the list across
OS X versions.  Instead we should automatically detect the framework
directories for the active toolchain.

The parent commit added the "-Wl,-v" option to ask "ld" to print its
implicit directories.  It displays a block such as:

 Framework search paths:
	/...

Parse this block to extract the list of framework directories.

Detection may fail on toolchains that do not list their framework
directories, such as older OS X linkers.  Always treat the paths

 <sdk>/Library/Frameworks
 <sdk>/System/Library/Frameworks
 <sdk>/Network/Library/Frameworks # Older OS X only
 /System/Library/Frameworks

as implicit.  Note that /System/Library/Frameworks should always be
considered implicit so that frameworks CMake finds there will not
override the SDK copies.

Kitware Robot 9db3116226 Remove CMake-language block-end command arguments
Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block.  This is no longer the preferred style.

Run the following shell code:

for c in else endif endforeach endfunction endmacro endwhile; do
    echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
egrep -z -v 'Tests/CMakeTests/While-Endwhile-' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed

Kitware Robot 77543bde41 Convert CMake-language commands to lower case
Ancient CMake versions required upper-case commands.  Later command
names became case-insensitive.  Now the preferred style is lower-case.

Run the following shell code:

cmake --help-command-list |
grep -v "cmake version" |
while read c; do
    echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed

Kitware Robot 7bbaa4283d Remove trailing whitespace from most CMake and C/C++ code
Our Git commit hooks disallow modification or addition of lines with
trailing whitespace.  Wipe out all remnants of trailing whitespace
everywhere except third-party code.

Run the following shell code:

git ls-files -z -- \
 bootstrap doxygen.config '*.readme' \
 '*.c' '*.cmake' '*.cpp' '*.cxx' \
 '*.el' '*.f' '*.f90' '*.h' '*.in' '*.in.l' '*.java' \
 '*.mm' '*.pike' '*.py' '*.txt' '*.vim' |
egrep -z -v '^(Utilities/cm|Source/(kwsys|CursesDialog/form)/)' |
egrep -z -v '^(Modules/CPack\..*\.in)' |
xargs -0 sed -i 's/ \+$//'

Stephen Kelly 55d7aa4c44 Add platform variable for flags specific to shared libraries
Store in CMAKE_${lang}_COMPILE_OPTIONS_DLL flags from
CMAKE_SHARED_LIBRARY_${lang}_FLAGS that are truly exclusive to shared
libraries.

Stephen Kelly 31d7a0f2e3 Add platform variables for position independent code flags
Store in new platform variables

  CMAKE_${lang}_COMPILE_OPTIONS_PIC
  CMAKE_${lang}_COMPILE_OPTIONS_PIE

flags for position independent code generation.

In almost all cases, this means duplication of the
CMAKE_SHARED_LIBRARY_${lang}_FLAGS for the _PIC case and using the
assumed pie equivalent for the _PIE case.  Note that the GNU compiler
has supported -fPIE since 3.4 and that there is no -fPIC on GNU for
Windows or Cygwin.

There is a possibility that the _PIE variables are not correct.
However, as there is no backwards compatibility to be concerned about
(as the POSITION_INDEPENDENT_CODE property is not used anywhere yet),
the current state suffices.

Brad King fa7141f5ad Add framework to detect compiler version with its id (#12408)
Teach CMakePlatformId.h to construct an "INFO:compiler_version[]" string
literal from macros COMPILER_VERSION_(MAJOR|MINOR|PATCH|TWEAK) to be
defined in CMake(C|CXX)CompilerId.(c|cpp) for each compiler.  Provide
conversion macros DEC() and HEX() to decode decimal or hex digits from
integer values.  Parse the version out of the compiler id binary along
with the other INFO values already present.

Store the result in variable CMAKE_<LANG>_COMPILER_VERSION in the format
"major[.minor[.patch[.tweak]]]".  Save the value persistently in
CMake(C|CXX)Compiler.cmake in the build tree.  Document the variable for
internal use since we do not set it everywhere yet.

Report the compiler version on the compiler id result line e.g.

  The C compiler identification is GNU 4.5.2

Report CMAKE_(C|CXX)_COMPILER_(ID|VERSION) in SystemInformation test.

Brad King 9daa4a6c3f Remove CMAKE_SHARED_MODULE_RUNTIME_${lang}_FLAG
This platform configuration variable is unused.  Modules are built using
the value of CMAKE_SHARED_LIBRARY_RUNTIME_${lang}_FLAG.

Brad King e55bbab88b Teach Xcode generator to set XCODE_VERSION
We set the variable 'XCODE_VERSION' in the CMake language to the Xcode
version string (e.g. "3.1.2").  Platform config files may use it later.

Brad King 0afa7a95f2 ENH: Report CMake logs in SystemInformation test
This teaches the SystemInformation test to report the CMake log files
CMakeOutput.log and CMakeError.log from the CMake build tree and from
the SystemInformation test build tree.  These logs may help diagnose
dashboard problems remotely.

Brad King 07ea19ad1f ENH: Implicit link info for C, CXX, and Fortran
This teaches CMake to detect implicit link information for C, C++, and
Fortran compilers.  We detect the implicit linker search directories and
implicit linker options for UNIX-like environments using verbose output
from compiler front-ends.  We store results in new variables called

  CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES
  CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES

The implicit libraries can contain linker flags as well as library
names.

Brad King 924dd34451 BUG: Fix SystemInformation dump output
When this test was renamed from DumpInformation to SystemInformation the
configured header that points the dump executable to the directory
containing information files was broken.  No information has been dumped
by this test for 2 years!  This fixes it.
