void | setEscapedAndAborted (Instruction *I=nullptr) |
Mark the pointer as escaped, and the visit as aborted. | |
This class provides information about the result of a visit.
After walking all the users (recursively) of a pointer, the basic infrastructure records some commonly useful information such as escape analysis and whether the visit completed or aborted early.
