* Check un-init not-null constructor fieldsCliff Click2026-09-281-1/+5
| | | | | | | | Propagate BOT inputs; Arith, Load. CallEnd inlining, the FUnPtr dies early. Load asserts when loading against uninit not-null field. Keep not-nill state for storage class. Clean up Node.peep as constant.

* Extend and backport SubNode peephole (#254)Hsiang-Ying Fu2026-09-252-0/+35
| | | | | | | | | | | | | | | * Extend and backport SubNode peephole * Add tests * Restrict subtraction zero peepholes to integer operands Require resolved integer mode in chapter 25 so zero subtraction preserves floating-point signed zero. Keep nonnumeric operands in the graph for subtraction diagnostics. Add signed-zero coverage from chapter 12 and null-subtraction diagnostics from chapter 22. Confirmed the regressions fail on the original PR. Full Make suites pass in chapters 4-25 (5462 tests), including fresh chapter 25 sys.o compilation. --------- Co-authored-by: Cliff Click <cliffc@acm.org>
