46 * G_BREAKPOINT:
47 *
48 * Inserts a breakpoint instruction into the code.
49 *
50 * On architectures which support it, this is implemented as a soft interrupt
51 * and on other architectures it raises a `SIGTRAP` signal.
52 *
53 * `SIGTRAP` is used rather than abort() to allow breakpoints to be skipped past
54 * in a debugger if they are not the desired target of debugging.
