Here's an example:

MSP432 EMT on Energia 18 fails, even for the blinky example.

MSP432 EMT on Energia 19 succeeds to compile the SwitriggerLibrary example.

Suggested solution

Add to the TI-RTOS closure a list of available and implemented elements, e.g.

#define EMT_HAS_SWI 
#define EMT_HAS_TASKS
#define EMT_HAS_EVENT
#define EMT_HAS_SEMAPHORE
#define EMT_HAS_MAILBOX
#define EMT_HAS_TIMER
#define EMT_HAS_CLOCK

Two options: 

#define EMT_HAS_SWI 1 // 1 = SWI implemented, 0 = SWI not implemented

...to be tested with #if (EMT_HAS_SWI == 1) ... #endif

#define EMT_HAS_SWI // define = SWI implemented, comment 0 = SWI not implemented
// #define EMT_HAS_SWI // comment = SWI not implemented

...to be tested with #if defined(EMT_HAS_SWI) ... #endif

Moved to https://github.com/energia/emt/issues/3, as all EMT-supported boards are concerned.
