22 # Also newlib or picolibc may be created as add-ons. Thus always stating that LLVM does not have
23 # newlib or picolibc would be wrong. Same with stating that LLVM has newlib or Picolibc.
24 # The best assumption for TOOLCHAIN_HAS_<NEWLIB|PICOLIBC> is to check for the presence of
25 # '_newlib_version.h' / 'picolibc' and have the default value set accordingly.
26 # This provides a best effort mechanism to allow developers to have the newlib C / Picolibc library
28 # Developers can manually indicate library support with '-DTOOLCHAIN_HAS_<NEWLIB|PICOLIBC>=<ON|OFF>'
37 # Support for picolibc is indicated by the presence of 'picolibc.h' in the toolchain path.
