If not set, it signifies a control flow target (basic block offset). + `InputAddr` is omitted for equal offsets in input and output function. In this case, `BRANCHENTRY` bits are encoded separately in a `BranchEntries` bitvector. +Deleted basic blocks are emitted as having `OutputOffset` equal to the size of +the function.

It contains `NumSecEntryPoints` offsets denoting secondary entry points, delta encoded, implicitly starting at zero. |
