Brad King 39ebfc79e6 Ninja: Add explicit preprocessing step for Fortran
All Fortran sources need to be preprocessed before any source may be
compiled so that module dependencies can be (later) extracted.  Factor
out an explicit preprocessing step preceding compilation.  Use Ninja
depfile dependencies on the preprocessing step and then compile the
already-preprocessed source with a separate build statement that depends
explicitly only on the preprocessor output.  Later we will insert
dynamic discovery of module dependencies between these steps.

Brad King a66004bee0 Honor CMAKE_<LANG>_FLAGS[_<CONFIG>]_INIT set in toolchain files
Document these variables.

Change our convention for setting these variables from:

    set(CMAKE_C_FLAGS_INIT "...")

to

    string(APPEND CMAKE_C_FLAGS_INIT " ...")

so that any value previously set by a toolchain file will be used.

Automate the conversion with:

    sed -i 's/set *(\(CMAKE_\(C\|CXX\|Fortran\|RC\|ASM\|${[^}]\+}\)_FLAGS\(_[^_]\+\)\?_INIT \+"\)/string(APPEND \1 /' \
      Modules/Compiler/*.cmake Modules/Platform/*.cmake

and follow up with some manual fixes (e.g. to cases that already
meant to append).  Also revert the automated changes to contexts
that are not protected from running multiple times.

Brad King c736de7b28 Factor an <INCLUDES> placeholder out of <FLAGS> in rule variables
Teach the Makefile and Ninja generators to substitute for an <INCLUDES>
placeholder instead of putting -I in <FLAGS>.  Update our values for

  CMAKE_<LANG>_COMPILE_OBJECT,
  CMAKE_<LANG>_CREATE_ASSEMBLY_SOURCE, and
  CMAKE_<LANG>_CREATE_PREPROCESSED_SOURCE

to place <INCLUDES> just before <FLAGS>.

Steven Vancoillie 3556fb1b81 SunPro: Add position independent code flag for Fortran compiler 2015-03-20 13:05:05 -04:00
Brad King be1109d811 Oracle/Sun: Fix Fortran preprocessor rule generation
The SunPro Fortran compiler uses "-F" instead of "-E" to request
preprocessing.  The output does not go to stdout so use "-o" to
specify the output file.

This fixes the guess originally made by commit b6b37e30 (Makefile: Add
assembly and preprocessed targets for Fortran, 2014-11-05).

Clinton Stimpson 0ddfc51f6a Add -DNDEBUG to RelWithDebInfo flags where where Release flags had it.
Previously, it was inconsistent in that some platforms/compilers
had this flag for the RelWithDebInfo configuration and some didn't.
This fixes issue #11366.

Kitware Robot 77543bde41 Convert CMake-language commands to lower case
Ancient CMake versions required upper-case commands.  Later command
names became case-insensitive.  Now the preferred style is lower-case.

Run the following shell code:

cmake --help-command-list |
grep -v "cmake version" |
while read c; do
    echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed

Brad King 5c0c635a09 Fortran: Add support for free- and fixed-form flags
Define a "Fortran_FORMAT" target and source file property.  Initialize
the target property from a "CMAKE_Fortran_FORMAT" variable.  Interpret
values "FIXED" and "FREE" to indicate the source file format.  Append
corresponding flags to the compiler command line.

Brad King 1f06c33f8e Drop -rdynamic from Linux build rules
This is a GNU-specific option that should not be specified for all
compilers on Linux.  It tells the GNU compiler to pass -export-dynamic
to the linker to export symbols from executables for use by plugins.
Since we provide the ENABLE_EXPORTS target property to do the same thing
in a cross-platform way, there is no need to pass -rdynamic always.

Since the option is not useful for GNU tools and breaks other tools on
Linux we simply remove it from CMAKE_SHARED_LIBRARY_LINK_<lang>_FLAGS.
This also allows us to stop setting the variable in other Linux compiler
files just to erase the bad flag.

See issue #9985.

Brad King 9ee0f9801a Split SunPro compiler information files
This moves platform-independent SunPro compiler flags into separate
"Compiler/SunPro-<lang>.cmake" modules.  Platform-specific flags are
left untouched.

Brad King 07ea19ad1f ENH: Implicit link info for C, CXX, and Fortran
This teaches CMake to detect implicit link information for C, C++, and
Fortran compilers.  We detect the implicit linker search directories and
implicit linker options for UNIX-like environments using verbose output
from compiler front-ends.  We store results in new variables called

  CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES
  CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES

The implicit libraries can contain linker flags as well as library
names.
