struct CFIProgram::Instruction

Declaration

struct CFIProgram::Instruction { /* full declaration omitted */ };

Description

An instruction consists of a DWARF CFI opcode and an optional sequence of operands. If it refers to an expression, then this expression has its own sequence of operations and operands handled separately by DWARFExpression.
