Brad King 109a7a245a Ninja: Detect MSVC /showIncludes prefix with compiler flags (#15596)
Move detection over to the compiler id logic where we have already
constructed the list of compiler flags from ARG1 and CMAKE_<LANG>_FLAGS.
Pass the flags when we execute "cl" with "/showIncludes".  Also pass "/c"
because we only need to compile, not link.  Check the compiler process
exit code before trusting its output.

Brad King c73fbda66b CMakeDetermineCompilerId: Drop unused code path
The execute_process command always exists so we never need to fall back on
exec_program.

Stephen Kelly 7235334a2f Project: Determine default language dialect for the compiler.

Brad King 99d160385e CMakeDetermineCompilerId: Use per-language regex to match Xcode compiler tool

Brad King 8306108fd6 CMakeDetermineCompilerId: Simplify src reference in IDE projects
When constructing the "id_src" value for substitution into VS or Xcode
compiler id projects, the input "src" variable already contains the file
name with no path so we do not need get_filename_component.  We know
this because CMAKE_DETERMINE_COMPILER_ID_WRITE already references
"${src}" with this assumption.

Brad King 0d204c1c1d CMakeDetermineCompilerId: Try matching compiler output to detect id
Some compilers can only be distinguished by their compilation output
rather than preprocessor symbols or special flags.  Add infrastructure
to determine the compiler id by matching output.

Brad King 5f0dad75a9 CMakeDetermineCompilerId: Refactor id build/check loop logic
Callers of CMAKE_DETERMINE_COMPILER_ID initialize the
CMAKE_${lang}_COMPILER_ID to unset so we can check it at the end of each
loop iteration instead of the beginning.  This approach allows us to
break out of the loop as soon as we succeed.  It will also allow checks
to be added in more places within the loop later.

Brad King c65a060e1b CMakeDetermineCompilerId: Optionally try some flags before no flags
Teach CMAKE_DETERMINE_COMPILER_ID to optionally try detecting the
compiler id using some given flags before trying to detect it with no
special flags.  This will be useful for Fortran detection to distinguish
some compilers that use the preprocessors of others but have no macro of
their own by getting verbose output.

Gunnar Roth 886dcaa7c5 MSVC: Distinguish among ARM architectures more precisely (#14552)

Brad King e6ebc814df Fortran: Add infrastructure to detect compiler version (#15372)
Fortran does not offer syntax to compose a string literal at
preprocessing time from numeric compuations.  Instead encode each digit
of each component as a separate INFO string and compose them in CMake
code after extraction.  Support MAJOR, MINOR, PATCH, and TWEAK
components with up to 8 digits each.

In commit v3.1.0-rc1~113^2 (Use a more reliable regex for extracting

more strict and no longer matches just "INFO:qnxnto".  Use

Brad King 7b7209f635 Xcode: Do not require code signing for compiler id (#15214)
The approach in commit v3.1.0-rc1~1^2 (Xcode: Fix compiler id detection
when code signing is required, 2014-10-22) still requires a code signing
key when targeting a real device.  Instead set CODE_SIGNING_REQUIRED to
"NO" to tell Xcode not to sign at all.  Drop the corresponding setting
of the code signing identity.

Brad King 7f89552a8f Xcode: Fix compiler path detection for iOS tools on Xcode <= 5.0 (#15237)
Since commit v3.1.0-rc1~1^2~1 (Xcode: Fix compiler id detection for iOS
tools, 2014-10-22) our compiler id detection project sets the product
type to 'com.apple.product-type.bundle.unit-test'.  This causes the Ld
command line on which we match the path to the compiler to have a
'CompilerIdC.xctest/' component.  The commit updated our regex to match
this, but placed it before the extra './' component that Xcode 5.0 and
below produce.  Xcode <= 5.0 prints '/./CompilerIdC.xctest/', so switch
the order of the two components in the regex to match it.

Brad King b91020f659 Xcode: Fix compiler id detection when code signing is required
The iOS product type 'com.apple.package-type.bundle.unit-test' requires
code signing on Xcode 6.  Other iOS target types do too.  Until CMake
learns to add the CODE_SIGN_IDENTITY build attribute itself, toolchain
files can set CMAKE_XCODE_ATTRIBUTE_CODE_SIGN_IDENTITY to tell the Xcode
generator to add the attribute.  Teach CMakeDetermineCompilerId to
recognize this variable and add the CODE_SIGN_IDENTITY build attribute
to the compiler id project.

Brad King c48f6e1229 Xcode: Fix compiler id detection for iOS tools (#15214)
Since commit 0cce556b (Xcode: Use sysroot and deployment target to
identify compiler, 2014-04-29) our compiler id detection project uses
the target platform SDK in case Xcode selects a different compiler based
on it.  Now the compiler id project actually compiles with the target
compiler and SDK when cross-compiling.

The iOS tools do not support the 'com.apple.product-type.tool' product
type we use in our compiler id detection project.  When targeting
iPhone, use product type 'com.apple.product-type.bundle.unit-test'
instead.

Ben Boeckel 29c3edb87a Avoid if() quoted auto-dereference

equivalent.

Use CMAKE_OSX_SYSROOT and CMAKE_OSX_DEPLOYMENT_TARGET to set the Xcode

because some versions of Xcode select a different compiler based on
these settings.  We need to make sure the compiler identified during
language initialization matches what will be used for the actual build.

Stephen Kelly e00db59d6c QNX: Introduce QCC compiler id for that QNX platform compiler.
Introduce policy CMP0047 to control resetting the id for
compatibility.

De-duplicate content in the QNX platform file by including the GNU
one. QNX is a form of GNU platform.

Do not clear CMAKE_SHARED_LIBRARY_${lang}_FLAGS variables.  They
are populated again later by the Compiler/GNU.cmake file anyway.

Modify the CMAKE_CXX_COMPILE_OBJECT variable only when the QCC
compiler id is in use, and the language is CXX.  Use the QNX
recommended flag for QCC instead of the gcc compatible -x flag.

Populate new module files to handle system includes and depfiles
when using the QCC compiler.

Remove code which unsets the system include and depfiles related
variables.  When a GNU driver is used instead of the QCC one, the
appropriate flags will be used.  These variables were previously
cleared for lowest-common-denominator compatibility with both
drivers.
