These options are defined specifically for the CR16 ports.
-mmac
Enable the use of multiply-accumulate instructions. Disabled by default.
-mcr16cplus-mcr16c
Generate code for CR16C or CR16C+ architecture. CR16C+ architecture is default.
-msim
Links the library libsim.a which is in compatible with simulator. Applicable to ELF compiler only.
-mint32
Choose integer type as 32-bit wide.
-mbit-ops
Generates sbit/cbit instructions for bit manipulations.
-mdata-model=model
Choose a data model. The choices for model are ‘near’,
‘far’ or ‘medium’. ‘medium’ is default.
However, ‘far’ is not valid with -mcr16c, as the
CR16C architecture does not support the far data model.
