Delay conversion of the path to object files (on the left-hand side
of dependencies) until just before they are written. Also do not
convert the format of paths written to the 'depend.internal' file.
This is consistent with the way the right-hand side of dependencies
are already handled.
From the GCC 4.9 release notes for Fortran:
https://gcc.gnu.org/gcc-4.9/changes.html
"Module files: The version of the module files (.mod) has been
incremented; additionally, module files are now compressed."
Teach cmDependsFortran::ModulesDiffer to look for the gzip magic numbers
at the beginning of the module file. If found, assume the module was
produced by gfortran >= 4.9. The modules do not appear to contain the
date as earlier versions did so we can compare the content directly
and do not actually need to decompress.
Use the clang RemoveCStrCalls tool to automatically migrate the
code. This was only run on linux, so does not have any positive or
negative effect on other platforms.
Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.
The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.
This patch is heavily inspired by Michael Wild.
The interfaces cmDepends::Write and cmDepends::WriteDependencies where
extended to allow multiple dependees (sources) per depender (object).
cmDepends::Write first collect all dependencies into a std::set before
passing it to cmDepends::WriteDependencies.
cmDependsC::WriteDependencies also first collects all explicit and
implicit dependencies into a std::set and only then writes
depend.{internal,make}. The implementation of cmDependsFortran simply
loops over all sources and proceeds as before, whereas the cmDependsJava
implementation is as trivial as before.
This is for preventing exponential growth of depend.{internal,make} in
the next commit which fixes dependency-vector erasure in
cmDepends::CheckDependencies.

Makefile dependencies must be escaped using cmLocalGenerator::Convert
with the cmLocalGenerator::MAKEFILE option. This fixes Fortran module
dependencies with spaces in the path. We test the fix by adding a space
to one of the module paths in the Fortran test.
This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
The previous change to Source/cmDependsFortran.cxx while refactoring
implicit dependency scanning configuration rules completely broke
loading of the include file search path while scanning Fortran
dependencies. This adds the line that should have been added during the
previous change to load the include path correctly.
- See issue #5809
- Keep information about all sources in the target until deps are written
- Create a fortran.internal file after scanning that lists modules provided
- Load fortran.internal files from linked targets to find modules
- Search the include path for external modules
- Create file-level deps on in-project module timestamps or external mods
