* More test case vs RA cleanupCliff Click7 days6-8/+13
| | | | | Missing a few risc/arm encodings. Make private many tests, so they don't escape and the escaped fcn inflate x86 spill numbers
* Towrds getting RA spill counts comparableCliff Click8 days14-4/+133
| | | | Ignore JIGs. Get test suites more conical, so reg alloc spill counts are comparable
* flt->int conversionCliff Click8 days13-4/+119
|
* RoundF32 actually roundsCliff Click8 days1-0/+1
|
* Make RA deterministicCliff Click8 days1-4/+12
|
* Small peep to drop simple store-updates out of loopsCliff Click10 days9-14/+69
|
* Require matching types to use algebraic identiesCliff Click10 days9-9/+9
| | | | Fixes some bugs `flit x; return x ^ 0;` should give an error instead of returning the plain `x`
* Slides for 2026 REBASEreadmeCliff Click11 days1-3/+4
|
* Chapter renumber, and split ch 17Cliff Click12 days49-1199/+1343
| | | | | | Renumber chapters 10a, 10b, 11, 12, 13, 14 -> 10, 11, 13, 12, [11,14]. Split ch 17 into a 17a and 17b; shuffle around im/mutable syntax to be consistent, and present it more slowly. THe new immutable syntax is pushed through all later chapters
* Fix bug loop tree depth on inf loopsCliff Click13 days9-13/+125
|
* Restore missing anti-dependence walkCliff Click14 days2-10/+33
|
* Move much of the ISA support to shared codeCliff Click14 days134-2482/+386
| | | | The ISA shared handlers here are required for a proper compiler, but contain only trivial bit-massaging operations.
* Move debug printing into shared spaceCliff Click14 days55-990/+363
| | | | Same as the graph viewer, moves a lot of code out of all Nodes
* Merge pull request #258: same constant phi merge testCliff Click2026-09-301-0/+15
|\ | | | | | | Preserve the regression across the Chapter 10 split by including it in both chapter10a and chapter10b. Validated Chapter05Test in all 22 affected snapshots (374 tests).
| * Add same constant phi merge testfuhsnn2026-09-291-0/+15

* | Finish forward-port mem ops thru ch25Cliff Click2026-09-3032-537/+1295
| |
* | Forward port mem stuff to ch21Cliff Click2026-09-306-9/+47
|/ | | | Also a minor reg-alloc improvement for BrainFuck, ported up to ch25
* Extend smaller-width C results to full widthCliff Click2026-09-2811-13/+242
|
* Backport FunPtrCliff Click2026-09-2810-13/+120
| | | | | Helps keep functions alive via ptr only (no calls). A few RISC 5 TFP encoding fixes.
* Support extern C ver direct updatesCliff Click2026-09-283-4/+36
| | | | FIx minor RISC encodings.
* Check un-init not-null constructor fieldsCliff Click2026-09-284-9/+13
| | | | | | | | 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.
* Remove -disablePeepholeCliff Click2026-09-278-92/+6
|
* bug fix widenCliff Click2026-09-263-13/+9
| | | | 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 Fu2026-09-254-4/+59
| | | | | | | | | | | | | | | * 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>
