`__addosi4`, `__addodi4`, `__addoti4`, `__subosi4`, `__subodi4`, and `__suboti4` were all functions which we invented for no apparent reason. Neither LLVM, nor GCC, nor the Zig compiler use these functions. It appears the functions were created in a kind of misunderstanding of an old language proposal; see https://github.com/ziglang/zig/pull/10824. There is no benefit to these functions existing; if a Zig compiler backend needs this operation, it is trivial to implement, and *far* simpler than calling a compiler-rt routine. Therefore, this commit deletes them. A small amount of that code was used by other parts of compiler-rt; the logic is trivial so has just been inlined where needed. I also chose to quickly implement `__addvdi3` (a standard function) because it is trivial and we already implement the `sub` parallel. |
