CHRE Overrides

CHRE provides nanoapps with a minimal list of overrides to standard library functions that are not supported by CHRE, but can be redirected to a supported function, or when failing silently should be of minimal consequences to the nanoapp. Two possible scenarios where the developers might need to use these overrides are:

• Generated code
• Third-party code/libraries

The overrides makefile is included in the nanoapp build by and enabled by default, but the developers can disable it by setting a flag in the nanoapp Makefile: CHRE_STD_OVERRIDES_ALLOWED = false

It is expected that the nanoapp developers only leverage these overrides while working towards zero overrides usage.
