* Split ch10Cliff Click2026-09-291-3/+24
| | | | Basic memory introduction in 10a, then precise aliases in 10b.
* Extend smaller-width C results to full widthCliff Click2026-09-281-9/+10
|
* Backport FunPtrCliff Click2026-09-281-16/+4
| | | | | Helps keep functions alive via ptr only (no calls). A few RISC 5 TFP encoding fixes.
* Support extern C ver direct updatesCliff Click2026-09-281-17/+47
| | | | FIx minor RISC encodings.
* Check un-init not-null constructor fieldsCliff Click2026-09-281-11/+34
| | | | | | | | 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.
* minor fixesCliff Click2026-09-271-6/+1
| | | | | Fix CI build Backport ch 23 fix to ch 22.
* Remove -disablePeepholeCliff Click2026-09-271-16/+3
|
* bug fix widenCliff Click2026-09-261-5/+2
| | | | Failed lattice law tests mixing constants and have wide type ints; or mixing wide ints and constant arrays.
* Extend and backport SubNode peephole (#254)Hsiang-Ying Fu2026-09-251-0/+1
| | | | | | | | | | | | | | | * 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>
* Keyboard shortcutsCliff Click2026-09-231-0/+1
| | | | | Fast forward/reverse, pick-a-frame. Shorter type names.
* int fallbacks for int opsCliff Click2026-09-221-0/+1
| | | | all chapters, a little sharper for int ops
* Final reg-alloc across chapters cleanupCliff Click2026-09-201-945/+179

* Split self-conflict phis once at a loop headCliff Click2026-09-201-3/+56
| | | | if this works, saves a copy-per-loop. If it fails, next round split as normal
* Popular use grouping for RegAllocCliff Click2026-09-201-4/+87
| | | | Fix arm BL encodings; ADD/SUB with reversed sign.
* Forward-port allocator bug fixes and test support through ch25Cliff Click2026-09-201-7/+207
| | | | Improved spilling
* Add back copy coaleascing in ch21Cliff Click2026-09-201-6/+81
| | | | Minor arm encoding fix.
* Ch 20 Reg AllocCliff Click2026-09-201-1/+137
| | | | | | | Includes all bug fixes from later chapters, so its at least correct. Skips a lot of improvement heuristics, these get added in later chapters. Includes spill-stats, to more easily track improvements. Includes targeted tests.

|
* Unify GCM across chaptersCliff Click2026-09-201-2/+70
| | | | | | Remove the _anti field. Remove the isPinned() call. Add a copyEmpty call.
