48 * G_BREAKPOINT:
49 *
50 * Inserts a breakpoint instruction into the code.
51 *
52 * On architectures which support it, this is implemented as a soft interrupt
53 * and on other architectures it raises a `SIGTRAP` signal.
54 *
55 * `SIGTRAP` is used rather than abort() to allow breakpoints to be skipped past
56 * in a debugger if they are not the desired target of debugging.
