A Note on Using the C Compiler Package for the R32C MCU Series V.1.01 Release 00


Please take note of the following problem in using the C Compiler package for the R32C MCU series V.1.01 Release 00:
  • With compile option -Wno_used_static_function(-WNUSF)


1. Description
   The compile option -Wno_used_static_function(-WNUSF) is a warning 
   option, which displays unused static functions.
   However, the C compiler V.1.01 Release 00 dispatches the following 
   warning message for all the static functions regardless of whether 
   you use static functions or not. Therefore, do not use this option.

   Message:
     Code generation for static functions (xxx) can be suppressed by
                           using -ferase_static_function(-fESF) option

   Here, option -ferase_static_function(-fESF) is a virtual one, so do not 
   use this also.

2. Schedule of Fixing the Problem
   We plan to fix this problem in V.1.02 Release 00.
