pub const drwrap_wrap_flags_t_DRWRAP_NO_DYNAMIC_RETADDRS: drwrap_wrap_flags_t = 2;Expand description
If this flag is set, then post-call callbacks are only invoked from return sites that can be identified statically. Static identification happens in two ways: from observing a CALL instruction, and from drwrap_mark_as_post_call(). Dynamically observing return addresses from inside callees incurs overhead due to synchronization costs, with further overhead to replace existing code with instrumented code. When this flag is set, some post-call callbacks may be missed.
