Brad King 340d0897fa Revert topic 'compiler-features-solaris'
Revert commit v3.4.0-rc1~10^2~2 (Features: Disable support for Oracle
SolarisStudio on non-Linux, 2015-09-29) and two follow-up commits.
The support of compile features and language standards on Orcale
SolarisStudio needs more investigation so for CMake 3.4 we should
just act as 3.3 did.

Brad King c824b23d15 Features: Fix C++98 flags on Oracle SolarisStudio 12.4 on Linux 2015-09-30 09:48:29 -04:00
Brad King 61bc0f7363 Features: Disable support for Oracle SolarisStudio on non-Linux
On SunOS the -std=c++11 flag must be used for linking as well as
compiling.  Until we implement support for this we cannot support
the CXX_STANDARD property except on Linux (where it was tested).

Stephen Kelly d13758514c Project: Don't require computed default dialect if compiler was forced.
Commit 7235334a (Project: Determine default language dialect for the
compiler., 2015-09-15) introduced a mechanism to determine the default
dialect used for the running compiler.  If conditions in
the <CompilerId>-<Lang>.cmake file are such that compile features for
that version of the compiler should be supported, the _DEFAULT_STANDARD
is set to the computed value.

However, the CMakeForceCompiler module allows users to bypass execution of the
compiler by CMake.  In that case, do not set the _DEFAULT_STANDARD variable at
all, which effectively disables the compile-features where the module is used.

No compile features have ever been recorded where the module is used so no
functionality is lost.

Stephen Kelly 7235334a2f Project: Determine default language dialect for the compiler.
Use the __cplusplus and __STDC_VERSION__ macros to automatically
determine the default dialect for the compiler while determining its
id and version.

Brad King c736de7b28 Factor an <INCLUDES> placeholder out of <FLAGS> in rule variables
Teach the Makefile and Ninja generators to substitute for an <INCLUDES>
placeholder instead of putting -I in <FLAGS>.  Update our values for

  CMAKE_<LANG>_COMPILE_OBJECT,
  CMAKE_<LANG>_CREATE_ASSEMBLY_SOURCE, and
  CMAKE_<LANG>_CREATE_PREPROCESSED_SOURCE

to place <INCLUDES> just before <FLAGS>.

Stephen Kelly 9d767810e1 Features: Populate CMAKE_<LANG>_STANDARD_DEFAULT only for supported compilers.
If no compiler feature information is known for a given compiler
version, do not set a language standard default either.  The two
settings must be recorded consistently.

Stephen Kelly bcb04783f7 Features: Record for SolarisStudio 12.4.
It has similar C++11 capabilities compared to GCC 4.8.

Clinton Stimpson 0ddfc51f6a Add -DNDEBUG to RelWithDebInfo flags where where Release flags had it.
Previously, it was inconsistent in that some platforms/compilers
had this flag for the RelWithDebInfo configuration and some didn't.
This fixes issue #11366.

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

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 1f06c33f8e Drop -rdynamic from Linux build rules
This is a GNU-specific option that should not be specified for all
compilers on Linux.  It tells the GNU compiler to pass -export-dynamic
to the linker to export symbols from executables for use by plugins.
Since we provide the ENABLE_EXPORTS target property to do the same thing
in a cross-platform way, there is no need to pass -rdynamic always.

Since the option is not useful for GNU tools and breaks other tools on
Linux we simply remove it from CMAKE_SHARED_LIBRARY_LINK_<lang>_FLAGS.
This also allows us to stop setting the variable in other Linux compiler
files just to erase the bad flag.

See issue #9985.

Brad King 9ee0f9801a Split SunPro compiler information files
This moves platform-independent SunPro compiler flags into separate
"Compiler/SunPro-<lang>.cmake" modules.  Platform-specific flags are
left untouched.

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.
