Instrument Control Flow For Indirect Branch Tracking
CET (Control-Flow Enforcement Technology) introduces a new mechanism called IBT (Indirect Branch Tracking).
According to IBT, each Indirect branch should land on dedicated ENDBR instruction (End Branch).
The new pass adds ENDBR instructions for every indirect jmp/call (including jumps using jump tables / switches).
