Presets:

• Change execve -> "rax==0xdeadbeef or rdi==0xdeadbeef or rdx==0 or rsi==0 or (disasm.has('syscall') and inst_cnt==1)"
• srop -> "rax==15 or (inst_cnt==1 and disasm.has('syscall'))"
• csu -> "disasm.has('pop rbp ; pop r12 ; pop r13 ; pop r14 ; pop r15') or disasm.has('mov rdx, r15 ;
  mov rsi, r14')" (depth needs to be high to detect full csu gadgets)
