# shift-base sanitizer is disabled due to the following pattern found in register header files:
# #define SOME_FIELD 0xFFFF
# #define SOME_FIELD_M ((SOME_FIELD_V)<<(SOME_FIELD_S))
# #define SOME_FIELD_V 0xFFFF
# #define SOME_FIELD_S 16
# here SOME_FIELD_V doesn't have an unsigned (U) prefix, so the compiler flags
# SOME_FIELD_M expansion (0xFFFF << 16) as generating integer overflow.

# Only enable UBSAN for a few components related to the panic test,
# due to RAM size limitations.
