Brad King a5e892ca1f Document compiler version macro formats used for detection
The MSVC, HP, XL, SunPro, Watcom, Borland, and Intel compilers specify
their version number in components encoded in a single integer value.
Document the components that we use to compute version numbers.

Brad King 3dd9fa9d6a Detect SunPro compiler version with its id
Decode hex digits from __SUNPRO_C and __SUNPRO_CC to compute the version
number components.  Note that the constant encodes decimal digits as hex
digits (never larger than 9).  We represent them as decimal after
extraction.  See documentation at

  http://predef.sourceforge.net/precomp.html

Although the documented version number format is

  0xVRP where V = Version, R = Revision, P = Patch

it holds only though SunPro C/C++ version 5.9.  Later versions have
a two-digit revision (minor) number so their format is 0xVRRP.

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 db05da35d2 Recognize SCO UnixWare C/C++ compilers (#11700)
These compilers define __SCO_VERSION__ as VvvYYYYMML:

     V = major version

  YYYY = release year
    MM = release month

Brad King dbc79bd8c8 Fix constness in compiler id detection
Since commit 70c2dc8a (Make compiler id detection more robust,
2008-03-10) we store compiler identification strings in test binaries
using the form

  char* info = "info";

Use the const-correct

  char const* info = "info";

form instead.  This allows the C++ compiler identification to work with
"-Werror -Wall" or equivalent flags if the compiler would warn about
const-to-non-const conversion.

Wojciech Migda f1392dc90b Recognize the Texas Instruments DSP compiler (#11645)
The TI DSP compiler predefines "__TI_COMPILER_VERSION__".  Use this to
identify the C and C++ compilers.  For assembler language the C compiler
executable is used:

  $ cl6x -h
  TMS320C6x C/C++ Compiler v6.1.11
  Tools Copyright (c) 1996-2009 Texas Instruments Incorporated

Use this command-line option and output to recognize the assembler.

Brad King 53e76c8f12 Teach CMake about Cray C, C++, and Fortran compilers
The Cray Fortran compiler needs "-em" to enable module output and also
"-J." to place the .mod files in the current working directory (instead
of next to the .o file).

Brad King 571dc74891 Recognize Clang C and C++ compilers (see #10693)
Map to the platform and compiler information for GNU because the
compilers are command-line compatible for common operations.  Later we
can add Clang-specific features as necessary.  We honor the preferred
capitalization is "Clang", not the common mis-spelling "CLang".

Brad King 115ecc5750 Teach compiler id about VisualAge -> XL rebranding
IBM rebranded its VisualAge compiler to XL starting at version 8.0.  We
use the compiler id "XL" for newer versions and "VisualAge" for older
versions.  We now also recognize the "z/OS" compiler, which is distinct
from XL.

Brad King 69e366f49b ENH: Check _SGI_COMPILER_VERSION for compiler id
Some SGI compilers define _SGI_COMPILER_VERSION in addition to the old
_COMPILER_VERSION preprocessor symbol.  It is more distinctive, so we
should check it in case the old one is ever removed.

Brad King b8fc8b324d ENH: Improve robustness of compiler INFO strings
Compiler INFO strings built at preprocessing time encode information
that must appear as a string literal in the resulting binary.  We must
make sure the strings appear in the final binary no matter what compiler
and flags are used.  The previous implementation worked in most places
but failed with the GNU linker's --gc-sections option which managed to
discard the string.  Instead we make the program return value depend on
an element of the string indexed by a runtime program parameter, which
absolutely requires the string to be present.

Brad King 70c2dc8a64 ENH: Make compiler id detection more robust
- Split INFO strings in source into multiple pieces
    to make sure assembly or other listings produced
    by the compiler are never matched by the regex
  - Store INFO strings via pointer instead of array
    to convince some compilers to store the string
    literally in the binary
  - This should help make it work for sdcc 2.8.0 RC1

Brad King 9211b0d234 ENH: Improvied compiler identification robustness
- Write a single source file into the compiler id directory

  - Helps to identify cross-compiling toolchains with unusual
    default behavior
