Support freezing modules via manifest.py for consistency with the other
ports. In essence this comes down to calling makemanifest.py and adding
the resulting .c file to the build. Note the file with preprocessed qstrs
has been renamed to match what makemanifest.py expects and which is also
the name all other ports use.
No functionality change is intended with this commit, it just consolidates
the separate implementations of GC helper code to the lib/utils/ directory
as a general set of helper functions useful for any port. This reduces
duplication of code, and makes it easier for future ports or embedders to
get the GC implementation correct.
Ports should now link against gchelper_native.c and either gchelper_m0.s or
gchelper_m3.s (currently only Cortex-M is supported but other architectures
can follow), or use the fallback gchelper_generic.c which will work on
x86/x64/ARM.
The gc_helper_get_sp function from gchelper_m3.s is not really GC related
and was only used by cc3200, so it has been moved to that port and renamed
to cortex_m3_get_sp.
Reserve sources.props for listing just the MicroPython core and extmod
files, similar to how py.mk lists port-independent source files. This
allows reusing the source list, for instance for building mpy-cross. The
sources for building the executable itself are listed in the corresponding
project file, similar to how the other ports specify the source files in
their Makefile.
We want the .vcxproj to be just a container with the minimum content for
making it work as a project file for Visual Studio and MSBuild, whereas the
actual build options and actions get placed in separate reusable files.
This was roughly the case already except some compiler options were
overlooked; fix this here: we'll need those common options when adding a
project file for building mpy-cross.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
Instead of having the PlatformToolset property hardcoded to a specific
version just set it to the value of DefaultPlatformToolset: this gets
defined according to the commandline environment in which the build was
started.
Instead of just supporting VS2015 the project can now be built by any
version from VS2013 to VS2017 and normally future versions as well, without
quirks like VS asking whether you want to upgrade the project to the latest
version (as was the case when opening the project in VS2017) or not being
able to build at all (as was the case when opening the project in VS2013).
Also adjust the .gitignore file to ignore any artefacts from VS2017.
- by default look for a user.props in the msvc directory, which is more convenient
than the built-in way of looking for such file in the user's home directory
- make git ignore the file
