Brad King a85e17e660 Intel: When simulating MSVC, re-use Windows-MSVC (#14476)
Teach CMake(C|CXX|Fortran)CompilerId* to report the MSVC version
simulated by the Intel compiler, if any.  Refactor the Windows-Intel
platform information helper module to load Windows-MSVC instead of
duplicating the information.  Teach Windows-MSVC to understand when
it is loaded as the simulated Fortran compiler (its preprocessor is
simulated).

Brad King 2e13c36211 OS X: Encode -F framework search flag in per-language platform variable
Compilers for languages other than C and C++ on OS X may not understand
the -F framework search flag.  Create a new platform information
variable CMAKE_<LANG>_FRAMEWORK_SEARCH_FLAG to hold the flag, and set it
for C and CXX lanugages in the Platform/Darwin module.

Adrien Destugues 7ebc1cb2ff Haiku: Several fixes to platform module
* Do not define BEOS anymore (this includes workarounds which we don't
  need most of the time in Haiku, so we prefer opt-in IF(HAIKU) in the
  cmake files instead).
* On the other hand, do define UNIX (we are trying to be compliant) and
  HAIKU (there is still a number of things we don't do like the
  average UNIX clone)
* Do not use UnixPaths, as our filesystem hierarchy isn't anything like
  what it expects.
* Do not use -nostart, which the compiler doesn't know about anymore.
  This used to be an Haiku extension to gcc, and is equivalent to
  -shared which is the default gcc option.
* While "dl" functions are provided in libroot, this is always
  implicitly linked so there is no need to tell cmake about it.
* Forcing position-independent code is not needed, so remove it.
* On the other hand, include appropriate linker options for executables
  and shared libraries.
* Support for the two available compilers in Haiku (gcc2 and gcc4) and
  pick the right headers and libraries according to the currently
  selected one.
* With the adoption of the package manager, the directory layout was
  changed. Tell cmake where to look for header files and libraries.
* As we don't define BEOS anymore, enable the workaround we still need
  for HAIKU as well. This is the lack of a libm (it is part of the
  implicitly linked in libroot)

that simply include the upstream equivalents.

Brad King f9eee7f183 Windows: Search '/' prefix only when cross compiling (#10994)
Commit dac78148 (...makes the mingw cross compiler work out of the
box..., 2007-08-02) added to CMAKE_SYSTEM_PROGRAM_PATH and
CMAKE_SYSTEM_LIBRARY_PATH paths like "/bin" and "/lib" with no Windows
drive letter so that cross-compiling to Windows from Linux would search
these paths under CMAKE_FIND_ROOT_PATH.  Later commit 2a782880 (...use
CMAKE_SYSTEM_PREFIX_PATH when possible, 2008-01-16) generalized this
approach by instead adding "/" to CMAKE_SYSTEM_PREFIX_PATH.

Both commits assumed that the paths would never match anything on
Windows hosts without a drive letter.  However, Windows evaluates these
paths relative to the current working drive letter so find_* commands
may report paths like "/lib/..." when paths like "c:/lib/..." exist on
what happens to be current drive.  Such drive-less paths are not
reliable when the working drive changes, so we should not use them.

Fix WindowsPaths.cmake to add '/' to CMAKE_SYSTEM_PREFIX_PATH only when
cross-compiling to Windows from a non-Windows host.  This will avoid
searching and finding local paths without a drive letter on Windows.

Brad King 42ba1b08f3 VS: Separate compiler and linker PDB files (#11899, #14062)
The MS tools create two types of PDB files as explained here:

 http://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.71%29.aspx
 http://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.80%29.aspx
 http://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.90%29.aspx
 http://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.100%29.aspx

One is created by the compiler (/Fd) and the other by the linker (/pdb).
The two options should not specify the same file.  Split them up.

In the VS IDE generators, simply drop ProgramDataBaseFileName to
take the VS default "/Fd$(IntDir)vc$(PlatformToolsetVersion).pdb".

In the Makefile generators, set "/Fd" on the compile line to be
the directory containing object files (with a trailing slash the
compiler will add the "vc$(PlatformToolsetVersion).pdb" filename
automatically).  Drop the /Fd option from the exe link command
line and add "/pdb" instead (already done for dll linking).
Update these rules for both MSVC and Intel tools.

Drop support for PDB_OUTPUT_DIRECTORY and PDB_NAME in STATIC
libraries because the generated .pdb files are only from /Fd
and not real linker-generated .pdb files.  Update documentation to
clarify that the PDB_* properties are only for linker .pdb files.

This regresses the PDBDirectoryAndName test for STATIC libraries.
Since it is not clear at this time what should be done for STATIC
library .pdb files, comment out the relevant portion of the test
and leave a TODO comment.

The flag was added incorrectly by commit 9c3a6eb4 (Need -brtl when creating

"-brtl -bnortllib ...", -brtl implies "-brtllib", and -brtllib should only be

unnecessary to specify -brtl explicitly after -G.

Brad King baa33acbda AIX-GNU: Put implicit link directories in runtime libpath (#13909)
The GNU compiler front-ends on AIX invoke the linker with flags of the
form "-L/path/to/gnu/runtime/lib" to tell ld where to find the language
runtime libraries.  They depend on the default libpath behavior
documented in "man ld" to add the -L paths also to the runtime libpath
so the dynamic loader can find the language runtime libraries.  This
differs from platforms whose linkers have distinct -rpath flags that
non-system compilers can use to tell the dynamic loader where to find
their language runtime libraries.

Since commit 96fd5909 (Implement linking with paths to library files,
2008-01-22) CMake always passes "-Wl,-blibpath:" followed by any
project-defined RPATH plus "/usr/lib:/lib" in order to explicitly set
the runtime libpath and avoid getting all the project -L paths in the
runtime libpath.  The explicit libpath prevents the GNU compiler runtime
library -L paths from being placed in the libpath and then the dynamic
loader fails to find the language runtime libraries.

CMake already detects the implicit link directories for each language
since commit 07ea19ad (Implicit link info for C, CXX, and Fortran,
2009-07-23).  Add the implicit link directories to the explicit runtime
libpath for GNU compilers on AIX to fix this use case.

in generated programs should be 10 meg, 2003-06-12) CMake adds link flags to
select a 10MB stack.  At the time this was for consistency with our behavior on
MS, but that was recently removed by commit 51af1da3 (Remove "/STACK:10000000"
from default linker flags, 2012-11-23).

Change our Embarcadero link flags to select the default stack and heap settings
according to the compiler documentation.  This is more reliable than leaving
the flags out completely as it has been reported that the linker does not
always use its documented defaults.

Brad King cc676c3a08 OS X: Detect implicit linker framework search paths
Previously we hard-coded a list of implicit framework directories but
did not account for CMAKE_OSX_SYSROOT or for changes to the list across
OS X versions.  Instead we should automatically detect the framework
directories for the active toolchain.

The parent commit added the "-Wl,-v" option to ask "ld" to print its
implicit directories.  It displays a block such as:

 Framework search paths:
	/...

Parse this block to extract the list of framework directories.

Detection may fail on toolchains that do not list their framework
directories, such as older OS X linkers.  Always treat the paths

 <sdk>/Library/Frameworks
 <sdk>/System/Library/Frameworks
 <sdk>/Network/Library/Frameworks # Older OS X only
 /System/Library/Frameworks

as implicit.  Note that /System/Library/Frameworks should always be
considered implicit so that frameworks CMake finds there will not
override the SDK copies.

Brad King 2dd67c7ea0 OS X: Detect implicit link directories on modern toolchains
We detect the implicit link directories for the toolchain by adding a
flag to get verbose output from the compiler front-end while linking the
ABI detection binary.  Newer OS X toolchains based on Clang do not add
the implicit link directories with -L options to their internal
invocation of "ld".  Instead they use a linker that comes with the
toolchain and is already configured with the proper directories.

Add the "-Wl,-v" option to ask "ld" to print its implicit directories.
It displays them in a block such as:

 Library search paths:
	/...

Parse this block to extract the implicit link directories.

While at it, remove the checks introduced by commit efaf335b (Skip
implicit link information on Xcode, 2009-07-23) and commit 5195a664
(Skip implicit link info for multiple OS X archs, 2009-09-22).  Discard
the non-system link directories added by Xcode.  Discard all detected
implicit libraries in the multi-architecture case but keep the
directories.  The directories are still useful without the libraries
just to suppress addition of explicit -L options for them.
