test: add comprehensive copy_ir and SSA snapshot tests - #2937
Merged
Conversation
Add 42 tests covering: - All 26 IR operation types in copy_ir() - SSA variable conversion (local, state, temporary, reference, tuple) - Phi node generation for control flow (if/else, loops, nested) - Critical edge cases (LibraryCall subclass preservation, None lvalues) - Snapshot tests for SSA output stability These tests provide a safety net for future refactoring of the SSA conversion code.
