24 * RAII assertion guard that ensures VM state (specifically, all of RDS,
25 * including vmfp, vmsp, and vmpc) is not modified while it is in
26 * scope. VMProtect::Pause may be used if the protection should be temporarily
27 * disabled within a scope.
29 * The only rule for nesting is that no VMProtect structs may be constructed
30 * inside a scope containing a VMProtect::Pause struct. The scope containing
31 * the VMProtect::Pause struct may contain 0 or more VMProtect structs,
32 * although only the outermost VMProtect struct will do any real work.
