In https://github.com/ggml-org/llama.cpp/pull/13892, all arch-specific implementations were split out into a nested tree structure under ggml-cpu/arch. This conflicts with standard CGO layout where all arch-specific source files are expected to live in the same directory as the parent go module and use suffixes based on GOOS and GOARCH. As such, there were really two options for getting this to work: 1. Add a patch on top of the GGML sync to rearrange the files to match the GO layout convention 2. Use CGO directives to conditionally include the nested source files in the compilation units This commit does (2) in order to minimize the set of changes needed on top of the upstream file layout. To get this to work, there are two key things needed: 1. In cpu.go, #cgo directives are added to explicitly set __${GOARCH}__ in the preprocessor directives 2. In arch-impls.c|cpp, use an #ifdef | #elif defined | #endif chain to explicitly include the .c|.cpp files for the given architecture from the nested directory Branch: GraniteFour Signed-off-by: Gabe Goodhart <ghart@us.ibm.com> |
