            Why is the XOR swap optimized into a normal swap using the MOV instruction?
            Asked 2022-Mar-08 at 10:00

            While testing things around Compiler Explorer, I tried out the following overflow-free function for calculating average of 2 unsigned 32-bit integer:

            ...

            ANSWER

            Answered 2022-Mar-08 at 10:00

            Clang does the same thing. Probably for compiler-construction and CPU architecture reasons:

            • Disentangling that logic into just a swap may allow better optimization in some cases; definitely something it makes sense for a compiler to do early so it can follow values through the swap.

            • Xor-swap is total garbage for swapping registers, the only advantage being that it doesn't need a temporary. But xchg reg,reg already does that better.

            I'm not surprised that GCC's optimizer recognizes the xor-swap pattern and disentangles it to follow the original values. In general, this makes constant-propagation and value-range optimizations possible through swaps, especially for cases where the swap wasn't conditional on the values of the vars being swapped. This pattern-recognition probably happens soon after transforming the program logic to GIMPLE (SSA) representation, so at that point it will forget that the original source ever used an xor swap, and not think about emitting asm that way.

            Hopefully sometimes that lets it then optimize down to only a single mov, or two movs, depending on register allocation for the surrounding code (e.g. if one of the vars can move to a new register, instead of having to end up back in the original locations). And whether both variables are actually used later, or only one. Or if it can fully disentangle an unconditional swap, maybe no mov instructions.

            But worst case, three mov instructions needing a temporary register is still better, unless it's running out of registers. I'd guess GCC is not smart enough to use xchg reg,reg instead of spilling something else or saving/restoring another tmp reg, so there might be corner cases where this optimization actually hurts.

            (Apparently GCC -Os does have a peephole optimization to use xchg reg,reg instead of 3x mov: PR 92549 was fixed for GCC10. It looks for that quite late, during RTL -> assembly. And yes, it works here: turning your xor-swap into an xchg: https://godbolt.org/z/zs969xh47)

            xor-swap has worse latency and defeats mov-elimination

            with no memory reads, and the same number of instructions, I don't see any bad impacts and feels odd that it be changed. Clearly there is something I did not think through though, but what is it?

            Instruction count is only a rough proxy for one of three things that are relevant for perf analysis: front-end uops, latency, and back-end execution ports. (And machine-code size in bytes: x86 machine-code instructions are variable-length.)

            It's the same size in machine-code bytes, and same number of front-end uops, but the critical-path latency is worse: 3 cycles from input a to output a for xor-swap, and 2 from input b to output a, for example.

            MOV-swap has at worst 1-cycle and 2-cycle latencies from inputs to outputs, or less with mov-elimination. (Which can also avoid using back-end execution ports, especially relevant for CPUs like IvyBridge and Tiger Lake with a front-end wider than the number of integer ALU ports. And Ice Lake, except Intel disabled mov-elimination on it as an erratum workaround; not sure if it's re-enabled for Tiger Lake or not.)

            Also related:

            If you're going to branch, just duplicate the averaging code

            GCC's real missed optimization here (even with -O3) is that tail-duplication results in about the same static code size, just a couple extra bytes since these are mostly 2-byte instructions. The big win is that the a path then becomes the same length as the other, instead of twice as long to first do a swap and then run the same 3 uops for averaging.

            update: GCC will do this for you with -ftracer (https://godbolt.org/z/es7a3bEPv), optimizing away the swap. (That's only enabled manually or as part of -fprofile-use, not at -O3, so it's probably not a good idea to use all the time without PGO, potentially bloating machine code in cold functions / code-paths.)

            As noted, the C++ standard library doesn't currently support constexpr evaluation of cmath functions. However, that doesn't prevent individual implementations from having non-standard code. GCC has a nonconforming extension that allows constexpr evaluation.

            Answered 2021-Dec-30 at 08:54

            If you look closely at the specification of ranges​::​size in [range.prim.size], except when the type of R is the primitive array type, ranges​::​size obtains the size of r by calling the size() member function or passing it into a free function.

            And since the parameter type of transform() function is reference, ranges::size(r) cannot be used as a constant expression in the function body, this means we can only get the size of r through the type of R, not the object of R.

            However, there are not many standard range types that contain size information, such as primitive arrays, std::array, std::span, and some simple range adaptors. So we can define a function to detect whether R is of these types, and extract the size from its type in a corresponding way.

            Old x86-64 CPUs don't support lzcnt, so rustc/llvm won't emit it by default. (They would execute it as bsr but the behavior is not identical.)

            Use -C target-feature=+lzcnt to enable it. Try.

            More generally, you may wish to use -C target-cpu=XXX to enable all the features of a specific CPU model. Use rustc --print target-cpus for a list.

            In particular, -C target-cpu=native will generate code for the CPU that rustc itself is running on, e.g. if you will run the code on the same machine where you are compiling it.
