Member Data Documentation

unsigned EncoderBase.OpndRolesDesc.count

Total number of operands in the operation.

unsigned EncoderBase.OpndRolesDesc.defCount

Number of defs in the operation.

unsigned EncoderBase.OpndRolesDesc.useCount

Number of uses in the operation.

unsigned EncoderBase.OpndRolesDesc.roles

Operand roles, bit-packed.

A bit-packed info about operands' roles. Each operand's role is described by two bits, counted from right-to-left - the less significant bits (0,1) represent operand#0.

The mask is build by ORing OpndRole_Def and OpndRole_Use appropriately and shifting left, i.e. operand#0's role would be

• '(OpndRole_Def|OpndRole_Use)'
• opnd#1's role would be 'OpndRole_Use<<2'
• and operand#2's role would be, say, 'OpndRole_Def<<4'.
