3.18.15 FT32 Options

These options are defined specifically for the FT32 port.

-msim

Specifies that the program will be run on the simulator. This causes an alternate runtime startup and library to be linked. You must not use this option when generating programs that will run on real hardware; you must provide your own runtime library for whatever I/O functions are needed.

-mlra

Enable Local Register Allocation. This is still experimental for FT32, so by default the compiler uses standard reload.

-mnodiv

Do not use div and mod instructions.

-mft32b

Enable use of the extended instructions of the FT32B processor.

-mcompress

Compress all code using the Ft32B code compression scheme.

-mnopm

Do not generate code that reads program memory.
