Patch	Description	Author	Forwarded	Bugs	Origin	Last update
build-system.patch	Build and install shared and static libraries The upstream CMake build creates only a static library and has no install rules. Build a versioned shared library alongside the static one, let CMake install both libraries and the public header, and add a CTest test. diff --git a/CMakeLists.txt b/CMakeLists.txt index d24e1ba..dc95513 100644	Andreas Tille <tille@debian.org>	not-needed			2026-10-23
gssw_use_native_simd_on_x86.patch	Use native SIMD intrinsics on x86 instead of forcing SIMDe aliases The header and the library unconditionally defined SIMDE_ENABLE_NATIVE_ALIASES and included simde/x86/sse4.1.h (or sse2.h). GCC 16 now defines those SSE intrinsics natively in its own headers (avx512vlintrin.h/smmintrin.h/ tmmintrin.h), so any translation unit that includes gssw.h and then pulls in a native intrinsic header fails with redefinition errors, breaking reverse dependencies such as vg on unstable. On x86 include the compiler's own <smmintrin.h>/<emmintrin.h> depending on the enabled ISA; keep the SIMDe fallback for architectures without SSE2. The only SSE4.1-only intrinsic used by gssw.c (_mm_max_epu16) is emulated with SSE2 instructions so the shared library keeps its SSE2 amd64 baseline. diff --git a/src/gssw.c b/src/gssw.c index 9981bf6..3bc2704 100644	Andreas Tille <tille@debian.org>	no			2026-11-04
