cxx: implement static initialization guards
2017-01-04 11:25:55 -05:00
# Mark __cxa_guard_dummy as undefined so that implementation of static guards
# is taken from cxx_guards.o instead of libstdc++.a
build system: Use component.mk for all components, refactor bootloader build For config-only components, component.mk should now contain "COMPONENT_CONFIG_ONLY := 1" Also refactored some of the generation of linker paths, library list. This required cleaning up the way the bootloader project works, it's now mostly independent from the parent.

# If exceptions are disabled, ensure our fatal exception
# hooks are preferentially linked over libstdc++ which
# has full exception support
[C++]: wrapper functions around unwind code * Replaced all C++ exception related functions with wrappers if -fno-exception is used. This prevents linking of the corresponding code in libgcc. The code size will decrease by around 7-9 KB when building with -fno-exception. * added no except test app Closes https://github.com/espressif/esp-idf/pull/5380 Closes https://github.com/espressif/esp-idf/issues/5363 Closes https://github.com/espressif/esp-idf/issues/5224 Closes IDFGH-3153 Closes IDF-2577
