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).

Brad King fd38eda9fe Support multiple arguments in CC,CXX,FC values
Teach compiler identification to support values such as

  export CC='gcc -g -O2'

by separating the arguments on spaces.  We already do this for the
values of CFLAGS, CXXFLAGS, and FFLAGS.

Brad King 3c2ecbe74e Add alternate per-vendor compiler id detection
At least one Fortran compiler does not provide a preprocessor symbol to
identify itself.  Instead we try running unknown compilers with version
query flags known for each vendor and look for known output.  Future
commits will add vendor-specific flags/output table entries.

Brad King 3a666595c9 Convert CMake non-find modules to BSD License
This adds copyright/license notification blocks CMake's non-find
modules.  Most of the modules had no notices at all.  Some had notices
referring to the BSD license already.  This commit normalizes existing
notices and adds missing notices.

Alexander Neundorf 8aac17471c BUG: make compiler id detection (almost) work again with sdcc 2.8.0 RC1,
mail sent to Brad for the remaining issue
don't match

which appears in the assembler file generated from the C file by sdcc, but
make sure the first character after the [ is no double quote

Brad King 9211b0d234 ENH: Improvied compiler identification robustness
- Write a single source file into the compiler id directory
  - This avoid requiring the compiler to behave correctly with
    respect to include rules and the current working directory
  - Helps to identify cross-compiling toolchains with unusual
    default behavior

Brad King 4b2218045d ENH: Add support to CMAKE_DETERMINE_COMPILER_ID macro to try building the id source more than once with different extra flags added to the compiler.

Alexander Neundorf 474629568c ENH: check the magic code of the executable file to determine the executable
file format. Tested for ELF on x86 Linux, COFF and Mach-O prepared but
commented out since I don't have such systems available. Please have a look
a CMakeDetermineCompilerId.cmake and enable the test for them too.

Only add the option for using chrpath if the executable format is ELF

Alexander Neundorf 176fe63d15 ENH: UNIX, CYGWIN, WIN32, APPLE, QNXNTO and BEOS are not longer set in
cmMakefile.cxx, but now in the platform files and are now valid for the
target platform, not the host platform.
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 d44bd2551c BUG: use ${LANG}_COMPILER_ARG1 also here, otherwise some compilers won't be
able to compile e.g. the C++ source file (e.g. the ADSP compiler needs -c++
for compiling C++ files)

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.
