--- Comment #19 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Fixed for GCC 15

Barry's example in comment 8 now gives:

copy_b(A*, A*, A*):
        subq    %rdi, %rsi
        movq    %rdx, %rax
        movq    %rsi, %rdx
        testq   %rsi, %rsi
        jle     .L1
        movq    %rdi, %rsi
        movq    %rax, %rdi
        jmp     memcpy
.L1:
        ret


copy_b(B*, B*, B*):
        subq    %rdi, %rsi
        movq    %rdx, %rax
        movq    %rsi, %rdx
        testq   %rsi, %rsi
        jle     .L4
        movq    %rdi, %rsi
        movq    %rax, %rdi
        jmp     memcpy
.L4:
        ret
