vn_nary_op_s Struct Reference

#include <tree-ssa-sccvn.h>

Data Fields
unsigned int	value_id
ENUM_BITFIELD(tree_code) opcode unsigned	length: 16
hashval_t	hashcode
tree	result
tree	type
tree	op [1]

---

Detailed Description

N-ary operations in the hashtable consist of length operands, an opcode, and a type. Result is the value number of the operation, and hashcode is stored to avoid having to calculate it repeatedly.
