Ensure code is placed in its most logical and efficient location to improve maintainability and performance. This includes consolidating duplicate functionality into shared headers or utility files, and moving loop-invariant conditions outside of loops.

When you encounter duplicate functions across multiple files, consider moving them to a shared header as inline functions. For example, instead of having ggml_are_same_layout duplicated in ggml-alloc.c and ggml-backend.cpp, move it to ggml.h as an inline function.

Similarly, extract conditions that don’t change within loops to outside the loop:

// Instead of:
for (size_t i = 0, n = 3; i < n; ++i) {
    if (op->src[i] != NULL && (op->src[i]->type == GGML_TYPE_BF16 || op->type == GGML_TYPE_BF16)) {
        // ...
    }
}

// Extract the loop-invariant condition:
bool op_is_bf16 = (op->type == GGML_TYPE_BF16);
for (size_t i = 0, n = 3; i < n; ++i) {
    if (op->src[i] != NULL && (op->src[i]->type == GGML_TYPE_BF16 || op_is_bf16)) {
        // ...
    }
}

This approach reduces code duplication, improves performance by avoiding redundant checks, and enhances code readability by making the logic structure clearer.
