Stephen Kelly 0e9f4bc00c Introduce target property <LANG>_VISIBILITY_PRESET 
This is initialized by CMAKE_<LANG>_VISIBILITY_PRESET. The target
property is used as the operand to the -fvisibility= compile option
with GNU compilers and clang.

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.

Peter Collingbourne 6b5614f164 Ninja: Substitute <OBJECT> and <CMAKE_C_COMPILER> in depfile flags 
Patch by Amine Khaldi!

Also, start using the -MT flag to set a target name for depfiles.
This works around a bug observed in distcc, as explained in the
comment.  Based on a patch by Alexander Usov.

Peter Collingbourne 7eb8d9036c Provide dependency file flags to generator 
Causes compiler modules (currently only GNU) to set a
CMAKE_DEPFILE_FLAGS_${lang} variable, which communicates to
the generator the flags required to cause the compiler to create
dependency files.

Brad King 33f5a83a5d GNU: Fix CMAKE_INCLUDE_SYSTEM_FLAG_<lang> value (#12258)

Todd Gamblin 2cde67a781 Modules: Fix spelling 'To distributed' -> 'To distribute' 2010-08-09 08:48:31 -04:00
Brad King e28c16b482 Split GNU compiler information files 
This moves GNU compiler flags into new-style modules

  Compiler/GNU-<lang>.cmake
  Platform/<os>-GNU-<lang>.cmake

We use language-independent helper modules

  Compiler/GNU.cmake
  Platform/<os>-GNU.cmake

to define macros consolidating the information.
