Chapter 6: Using the Emulator
Using Software Breakpoints
The run-time library provided with the 68360 C Cross Compiler uses software
breakpoints to interrupt program execution when exceptions (for example, divide
by zero) are encountered. If software breakpoints are disabled, exception
processing may result in "access to guarded memory" errors and/or other
unpredictable behavior. To prevent this, a special global symbol,
XEnv_68k_except, is included in the library.
When the XEnv_68k_except symbol is present, the 68360 emulator writes a value
to this location. The value tells the run-time library to use the BGND instruction to
perform a software break.
Examples
To enable software breakpoints using the breakpoints display pop-up menu:
