SDCC currently has support for __typeof, which is an extension to the C standard. In SDCC, __typeof returns an integer constant that depends of the type of the operand. SDCC has had this support since 2001, but __typeof is not used in our library nor is it tested in the regression tests. When support for _Bool and long long got added to SDCC, the __typeof support was not updated to support them. __typeof support is quite a few lines of code in different places.
SDCC now supports _Generic from the ISO C11 standard. _Generic is more generic than __typeof. __typeof probably has few users if any, and most use cases of __typeof should be easy to migrate to _Generic. I suggest to drop support for __typeof. Philipp
