#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.
