Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Extend Version.h with macros for LLVM 16-20 support: - IF_LLVM_GTE_160 through IF_LLVM_GTE_200 with all variants Create Compat.h with compatibility wrappers for API changes: - GetSignificantBits(): handles getMinSignedBits() → getSignificantBits() (LLVM 17+) - GetZeroAPInt(): handles getNullValue() → getZero() (LLVM 17+) - MakeAttributeInfo(): handles AttributeCommonInfo constructor changes (LLVM 17+) - GetFieldBitWidth(): handles getBitWidthValue() signature change (LLVM 20+) - Enum constants: CharacterKind, StringKind, TagKind, etc. (LLVM 20+) - Optional: handles llvm::Optional → std::optional (LLVM 20+) This enables supporting LLVM versions 16, 17, 18, 19, and 20 with a single codebase. 🤖 Generated with

Add cmake/ccache.cmake: - Copied from remill for optional ccache support Update CMakePresets.json: - Remove vcpkg-specific presets - Simplify to basic debug/release configurations - Use Ninja

.github/workflows/ci.yml - .github/workflows/diff_tests.yml - .github/workflows/anghabench-after-build.yml Add new unified build matrix workflow: - .github/workflows/build.yml New CI configuration: - Tests LLVM versions 16, 17, 18, 19, 20 on both Linux and macOS - Uses system LLVM packages (apt.llvm.org on Linux, Homebrew on macOS) - Builds dependencies via superbuild with USE_EXTERNAL_LLVM=ON - Runs complete test suite with ctest - Uploads artifacts for LLVM 20 builds This replaces all previous CI infrastructure with a single, consistent workflow that leverages the new superbuild system. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .github/workflows/anghabench-after-build.yml | 141 ---------- .github/workflows/build.yml | 121 +++++++++ .github/workflows/ci.yml | 261 ------------------- .github/workflows/diff_tests.yml | 112 -------- 4 files changed, 121 insertions(+), 514 deletions(-) delete mode 100644 .github/workflows/anghabench-after-build.yml create mode 100644 .github/workflows/build.yml delete mode 100644 .github/workflows/ci.yml delete mode 100644 .github/workflows/diff_tests.yml diff --git a/.github/workflows/anghabench-after-build.yml b/.github/workflows/anghabench-after-build.yml deleted file mode 100644 index f2a564a2..00000000 --- a/.github/workflows/anghabench-after-build.yml +++ /dev/null @@ -1,141 +0,0 @@ -name: Run AnghaBench CI After Build -

The new RELLIC_FORCE_STATIC_LLVM option patches Clang CMake targets to use static LLVM libraries instead of the dylib. This works by: 1. Getting the list of static LLVM libraries via llvm-config --link-static 2.

This handles C++20 [[no_unique_address]] members, which can share storage with other members at the same offset. libc++ uses this extensively with __compressed_pair_padding fields. Previously, StructGenerator would CHECK-fail when encountering these overlapping fields because it assumed monotonically increasing offsets. The fix detects overlap (curr_offset > elem.offset) and skips the field, since [[no_unique_address]] fields don't contribute unique storage and aren't needed for physical struct layout reconstruction.
