<div><span style="font-family: Slack-Lato, Slack-Fractions, appleLogo, sans-serif; font-size: 15px; color: rgb(29, 28, 29);">We use ISC BIND for our IBM AIX, we build open source bind with AIX xlc compiler to make it work on AIX.</span></div>
<div class="elementToProof"><span style="font-family: Slack-Lato, Slack-Fractions, appleLogo, sans-serif; font-size: 15px; color: rgb(29, 28, 29);">AIX xlc compiler supports gcc __sync builtin functions. Currently bind-9.16 is used on AIX, now we are planning
to move bind from bind 9.16 to 9.18 but we see in 9.18, the support for clang atomic builtins and for gcc __sync builtins are removed .</span></div>
