Re: [Gems-users] Magic Instructions

[Dan Gibson <degibson@xxxxxxxx>]

Simics supports a variety of user-customizable magic services that all 
use magic instructions. You can find out more about them using via the 
magic instruction hap (Simics Reference Manual).
There is one built-in magic instruction, the magic break. For SPARC 
architectures, this corresponds to magic number 0x40000. Since your code 
below uses Magic #1, I'm not surprised that your code isn't stopping.
magic-instruction.h also defines the MAGIC_BREAKPOINT macro -- its much 
easier to use MAGIC_BREAKPOINT instead:
#define MAGIC_BREAKPOINT MAGIC(0x40000)
