The following works in avr-gcc 5.4.0, but is not legal C++, because ptr's are not legal constexpr's:
|
||||
constexpr auto *foo = ptr;
|
||||
|
||||
Workaround is to store the address of the ptr in a uintptr_t and reinterpret_cast it at call site.
|
||||
The _SFR_ADDR macro in sfr_defs.h would give the address, but it does that by taking the address of the dereferenced
|
||||
pointer and casts it to uint16_t, which is still not a legal constexpr.
|
||||
The workaround therefore is to disable the pointer-cast-and-dereference macro _MMIO_BYTE temporarily.
