示例1: installLocationFilterForLine
// Setup the last location filter on the VM context for all offsets covered by
// the current source line. This will short-circuit the work done in
// phpDebuggerOpcodeHook() and ensure we don't interrupt on this source line.
// We exclude continuation opcodes which transfer control out of the function,
// which allows cmds to get a chance to alter their behavior when those opcodes
// are encountered.
void CmdFlowControl::installLocationFilterForLine(InterruptSite *site) {
// We may be stopped at a place with no source info.
if (!site || !site->valid()) return;
