v40

Full Changelog: v39...v40

v39

CAHP Ruby patch release.

• Fixes CAHP relocation emission in bundled llvm-cahp so unresolved PC-relative fixups are recorded instead of being silently encoded as local offsets.
• Restores cahp-ruby startup: the bundled CAHP runtime now relocates jsal main correctly, so Ruby programs enter main and halt.
• Adds CAHP 10-bit PC-relative relocation support for branch fixups in object emission and lld.
• Publishes both default and AVX2 release artifacts with the corrected bundled runtime/toolchain.

v38

Highlights

• Add Alexandrite as a first-class RV32I KVSP CPU target.
• Bundle Alexandrite ROM/RAM blueprint, generated core, and freestanding RV32I runtime.
• Add masked Iyokan RAM writes for byte-lane RAM updates across plain, TFHEpp, and CUFHE paths.
• Build bundled LLVM with RISCV plus CAHP targets.
• Fix CUDA/cuFHEpp release builds with current TFHEpp, including Clang-hosted nvcc and AVX512 CUDA host compilation.
• Keep Ruby and Pearl CAHP flows available, with --cahp-cpu compatibility aliases.

Validation

• Verified toolbox.sh copy validates required Alexandrite, Ruby, Pearl, and runtime artifacts before packing.
• Verified the release package contains Alexandrite, Ruby, and Pearl core artifacts plus RV32I and CAHP LLVM targets.
• Verified both release Iyokan binaries report GPU support enabled at Iyokan revision 9e69a83.
• Verified Alexandrite plain execution for fib 5 returns #cycle=21, f0=true, and x10=5.
• Verified Alexandrite encrypted GPU execution with run --cpu alexandrite -g 1 -c 21 decrypts to #cycle=21, f0=true, and x10=5.

Changes from v35

Iyokan (be517a5 → 2c26bc7)

• Fix GPU RAM bootstrapping: disable USE_KEY_BUNDLE for cuFHEpp compatibility
• Bump cuFHEpp: update GPU-NTT remote to Alisah-Ozcan fork
• Support constant drivers and unknown cell types in YosysJSONReader

llvm-cahp (6344ad8 → 3e58287): rebase to LLVM 21

• Rebase CAHP backend onto LLVM 21.0.0
• Fix CMakeLists.txt: add required LINK_COMPONENTS to CAHPCodeGen and all CAHP subdirectory targets (Disassembler, AsmParser, MCTargetDesc, InstPrinter, TargetInfo)
• Fix PC-relative branch fixups: pass PCRel=true to MCFixup::create for fixup_cahp_pcrel_10 and fixup_cahp_pcrel_11. In LLVM 21, MCAssembler::evaluateFixup only subtracts the instruction PC when isPCRel() is true; without this fix, branch instructions encoded absolute section offsets and caused infinite loops at runtime.

v35

Changes

• Refactor Makefile for parallel builds (make -j now works correctly)
• Add clean target and BUILDDIR variable
• Add cmake configuration caching (skip re-runs)
• Update README: cuFHE → cuFHEpp, drop V100 references, replace AWS p3 with p4d instances
• Fix cmake policy compatibility for llvm-cahp

v34

Update all dependencies to make KVSP runnable on Ubuntu 24.04. VSP is still not dead.

v33

• Fix a bug that cahp-ruby wrongly set 0 to f0

v32

• Fix slower cahp-ruby

v31

• Fix a bug that cahp-ruby wrongly set 0 to f0
  • Thanks to @ankoman (#8)
