#include <tree-ssa-sccvn.h>

Data Fields

unsigned int value_id
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
