This change allows RTTI to be enabled in menuconfig. For full RTTI
support, libstdc++.a in the toolchain should be built without
-fno-rtti, as it is done now.
Generally if libstdc++.a is built with RTTI, applications which do not
use RTTI (and build with -fno-rtti) could still include typeinfo
structures referenced from STL classes’ vtables. This change works
around this, by moving all typeinfo structures from libstdc++.a into
a non-loadable section, placed into a non-existent memory region
starting at address 0. This can be done because when the application
is compiled with -fno-rtti, typeinfo structures are not used at run
time. This way, typeinfo structures do not contribute to the
application binary size.
If the application is build with RTTI support, typeinfo structures are
linked into the application .rodata section as usual.
Note that this commit does not actually enable RTTI support.
The respective Kconfig option is hidden, and will be made visible when
the toolchain is updated.
This commit makes it so that BUILD_COMPONENT holds only the component,
and a new property BUILD_COMPONENT_ALIASES hold the full name of the
component.
This also removes erroneous check for duplicate components, as this can
never happen:
(1) if two components have the same name but different prefixes,
the internal names are still unique between them
(2)if two components happen to have the same name and same prefix, the
latter would override the former
Previous implementation only builds list of components included in the
build during component registration.
Since the build components is known as the requirements expansion is
ongoing, update the list here instead.
Use imported library, which does not create additional rules, but still
allows attaching arbitraty properties instead of custom targets. This
allows the targets to not appear in the target list of IDEs such as
CLion.
Fixes an issue where if idf_build_process is called in a CMake
subdirectory, menuconfig looks for the mconf-idf binary in the wrong
place (in the subdirectory build dir instead of root binary dir).
- Makefile didn't quite work with out-of-tree build unless there was already an in-tree build done.
- CMake needs to delete some of the in-tree build artifacts or they're used instead of the correct
files.
