Instead of a complete expansion of nodes for code -- generation, this Alfa expansion targets generation of intermediate code -- for formal verification. -- Expand_Alfa is called directly by Expander.Expand. -- Alfa expansion has three main objectives: -- 1. Perform limited expansion to explicit some Ada rules and constructs -- (translate 'Old and 'Result, replace renamings by renamed, insert -- conversions, expand actuals in calls to introduce temporaries) -- 2. Facilitate treatment for the formal verification back-end (fully -- qualify names, set membership) -- 3. Avoid the introduction of low-level code that is difficult to analyze -- formally, as typically done in the full expansion for high-level -- constructs (tasking, dispatching) with Types; use Types; package Exp_Alfa is procedure Expand_Alfa (N : Node_Id); end Exp_Alfa;
