| basic_block | block |
| tree | type |
| tree | result |
Detailed Description
Phi nodes in the hashtable consist of their non-VN_TOP phi arguments, and the basic block the phi is in. Result is the value number of the operation, and hashcode is stored to avoid having to calculate it repeatedly. Phi nodes not in the same block are never considered equivalent.
