RFC: inbounds on getelementptr indices for global splitting
....org/D22295 regarding an earlier implementation of
global splitting, which was based on metadata. I'm posting this new
proposal as an RFC as the increased intrusiveness in the IR warrants
greater visibility.
Example
i8** getelementptr inbounds ({[4 x i8*], [4 x i8*]}, {[4 x i8*], [4 x
i8*]}* @_ZTVfoo, i32 0, inbounds i32 1, i32 2)
This is a reference to the address point of the second element of _ZTVfoo,
a virtual table group with two virtual tables, such that any pointer
extending beyond the bounds of the second virtual table is a poison value.
Alternatives
We could consider attaching metad...
