A better ASSERT

Is there an instruction or register that can be used to cause the processor to break into the debugger? I see ASSERT written with while(1) in example code, but I would imagine there's something more direct than having to hit pause just to see if you've failed.

Assuming you are linking with the semihosted variant of the Redlib C library, then assert has been recoded for the next version of redlib ("Redlib_v2", a beta of which is included within the Linux beta of LPCXpresso) such that it will terminate execution of the program, rather than going in to a while(1) loop.

In the meantime, if you want to cause program termination yourself, then you can call the function from within the semihosting layer of Redlib:

void __exit(void);

Note that this interface to the semihosting layer in Redlib_v2 has unfortunately had to change slightly, and __exit() will become __sys_appexit().

There are a few more notes on Redlib_v2 for anyone who is interested:

Yes, I'm interested :)

Is this

included in the next release of Windows-LPCXpresso?

Perfect, thanks.
