|
|
<p>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.

<p>Enable Local Register Allocation. This is still experimental for FT32,
|
||
|

so by default the compiler uses standard reload.
