xollvm — v0.10.0

Built against stock LLVM release/22.x.

Highlights

This release lands MBA extension v3 — memory-free, solver-resistant Mixed Boolean-Arithmetic strengthening for the mba pass, plus preset bundles and a SiMBA resilience harness.

What's new

MBA pass (mba)

  • Memory-free input-derived runtime-zero inflation — zeros are lifted from function inputs, no volatile memory scratch (defeats store-forwarding folds).
  • SLE pool: nonlinear-lifted runtime zeros drawn from a 260-entry system-of-linear-equations pool (MBASlePool.inc), resistant to InstCombine canonicalization.
  • Preset bundles: light / medium / high / max for one-knob strength selection.

Docs

  • docs/USER.md documents the memory-free input-zero and SLE options.
  • README now points to the xollvm.github.io docs site.

Tooling / tests

  • SiMBA attack + MBA resilience bench cases in utils/deobf_bench/ (attacks/simba.py, new mba_ops program templates).
  • MBA correctness, fold-check, and SLE generate/verify utilities (utils/mba_fold_check.py, utils/mba_sle_gen.py, utils/mba_sle_verify.py).

Chore

  • Dropped prototype demo/perf scratch; .gitignore globs guard future scratch.

Merged PRs

  • #18chore/drop-demo-scratch: drop prototype scratch, ignore future scratch
