Brad King 51ab85c398 CMakeDetermineCompilerId: Add notion of "simulated" id/version
Some compilers try to simulate other compilers as a drop-in replacement
supporting all the same command-line options and predefined preprocessor
macros.  In such cases it will be useful to have CMake load the compiler
information files for the simulated compiler instead of duplicating the
information.  Teach CMakeDetermineCompilerId to extract the simulated
compiler id and version when the compiler id detection provides it.

Patrick Gansterer 8bb3b3d344 VS: Use version-specific subsystem for WinCE compiler id (#14440)
The subsystem must be set to WINDWOSCE for some SDKs to link an
executable. Set it to 9 for VS2005 and to 8 for VS2008, since the
value differs between the different Visual Studio versions.

Patrick Gansterer b02f09d434 VS: Replace ArchitectureId with PlatformName
Since we do not need the information about the target architecture
we can use the PlatformName only to specify the this information.
This also removes setting of the MSVC_*_ARCHITECTURE_ID variable
which is not required, because this variable gets set by the
compiler detection code in CMAKE_DETERMINE_COMPILER_ID_CHECK().

Patrick Gansterer 60e568cf79 VS10: Do not set the TargetMachine when detecting the compiler
The Microsoft linker is intelligent enough to detect the target
machine type depending on the input files. This allows us to
get the target architecture from the compiler instead of
maintaining the mapping to the platform name.

Patrick Gansterer dfbfe6f166 VS6: Hardcode id_machine_6 for compiler detection
id_machine6 is never set to an other value than x86. So it is

Patrick Gansterer 40c36c9f7b VS: Make DetermineCompilerId working with WinCE too

Patrick Gansterer 14861f88d2 VS: Remove TargetMachine for linker when checking compiler id
If the TargetMachine isn't defined the linker will choose

Brad King 7ee3cee919 VS11: Add VS 2012 Express support (#13348)
Use the registry entries that vsvars32.bat uses to detect the location of
MSBuild.exe in the framework directory.  Invoke MSBuild with the option

 /p:VisualStudioVersion=$version

so it knows from which VS version to load the system build rules.  Teach
cmGlobalVisualStudio11Generator to set its ExpressEdition member using the
registry.

Brad King 7195aca54f Make platform information files specific to the CMake version
At the top of a build tree we configure inside the CMakeFiles directory
files such as "CMakeSystem.cmake" and "CMake<lang>Compiler.cmake" to
save information detected about the system and compilers in use.  The
method of detection and the exact results store varies across CMake
versions as things improve.  This leads to problems when loading files
configured by a different version of CMake.  Previously we ignored such
existing files only if the major.minor part of the CMake version
component changed, and depended on the CMakeCache.txt to tell us the
last version of CMake that wrote the files.  This led to problems if the
user deletes the CMakeCache.txt or we add required information to the
files in a patch-level release of CMake (still a "feature point" release
by modern CMake versioning convention).

Ensure that we always have version-consistent platform information files
by storing them in a subdirectory named with the CMake version.  Every
version of CMake will do its own system and compiler identification
checks even when a build tree has already been configured by another
version of CMake.  Stored results will not clobber those from other
versions of CMake which may be run again on the same tree in the future.
Loaded results will match what the system and language modules expect.

Rename the undocumented variable CMAKE_PLATFORM_ROOT_BIN to
CMAKE_PLATFORM_INFO_DIR to clarify its purpose.  The new variable points
at the version-specific directory while the old variable did not.

Brad King 66cb3356f5 VS: Detect the compiler id and tool location

Brad King 965a69dcaa Xcode: Detect the compiler id and tool location
Configure a hand-generated Xcode project to build the compiler id source
file since we cannot run the compiler command-line tool directly.  Add a

setting.  Run xcodebuild to compile the identification binary.  Parse
the full path to the compiler tool from the xcodebuild output.

Brad King 9a9e1ee98d CMakeDetermineCompilerId: Prepare to detect IDE compiler id
Teach CMAKE_DETERMINE_COMPILER_ID to check for variable
CMAKE_${lang}_COMPILER_ID_TOOL after CMAKE_DETERMINE_COMPILER_ID_BUILD
to use as CMAKE_${lang}_COMPILER since it will not be known until after
the IDE runs.

In CMAKE_DETERMINE_COMPILER_ID_BUILD prepare a cascading "if" so we can
use a generator-specific method to compile the identification source
file.  Leave "if(0)" as a placeholder for now and put the direct
compiler invocation in "else()".  After running the compiler to build
the compiler identification source we file(GLOB) the list of output
files as candidates for extracting the compiler information.  An IDE may
create directories, so exclude exclude directories from this list.

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.

for c in else endif endforeach endfunction endmacro endwhile; do
    echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed &&

Kitware Robot 77543bde41 Convert CMake-language commands to lower case

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.

Alex Neundorf e6c9bc267b Add timeout to execute_process() in CMAKE_DETERMINE_COMPILER_ID().
In CMAKE_DETERMINE_COMPILER_ID_VENDOR() the compiler is called with various
arguments. In some cases, this can make the compiler hang and wait
forever for input (e.g. "as -v"). That's why add an timeout
so it terminates finally. 10 seconds should be more than enough,
this is the time it takes to startup the compiler, which is
usually quite fast.

Alex Neundorf b333779e34 Detect a COMPILER_ID also for ASM.
For assembler, the "compiler ID" cannot be detected by "compiling" a
source file, since there is not source file all assemblers understand.
Instead the function CMAKE_DETERMINE_COMPILER_ID_VENDOR() is used to
run the assembler and check its output.
For this the CMAKE_DETERMINE_COMPILER_ID_VENDOR() function had to be
extended so that it creates the run directory if it doesn't exist yet.

In CMakeASMInformation.cmake now also CMAKE_ASM_COMPILER_ID is used
(but there are no such files yet, will come with the support for the
IAR toolchain).

New variables CMAKE_HOST_WIN32, CMAKE_HOST_UNIX, CMAKE_HOST_APPLE and
CMAKE_HOST_CYGWIN have been added in cmMakefile.cxx (...and have now to be
used in all cmake files which are executed before
CMakeSystemSpecificInformation.cmake is loaded). For compatibility the old
set is set to the new one in CMakeDetermineSystem.cmake and reset before the
system platform files are loaded, so custom language or compiler modules
which use these should still work.

Alexander Neundorf 55f11b348b ENH: add option to FILE(STRINGS NO_HEX_CONVERSION) to disable automatic
conversion of hex and srec files to binary.
Without this automatic conversion, everywhere where a compiled file is parsed for strings the
a file(HEX2BIN somefile binfile) command has to be added otherwise it will
not work for these compilers. I tried this with DetermineCompiler and
CheckTypeSize and nobody will do this except the users who work with such
compilers. For them it will break if they don't add this conversion command
in all these places.
If FILE(STRINGS) is used with a text file, it
will in most cases still work as expected, since it will only convert hex
and srec files. If a user actually wants to get text out of hex files, he
knows what he's doing and will see the hint in the documentation.

Anyway, it should work without having to create a temporary file, will work
on this later.
