This code block breaks the docs build (http://lab.llvm.org:8011/builders/llvm-sphinx-docs/builds/11920/steps/docs-llvm-html/logs/stdio), but I cannot see anything immediately wrong with it and cannot reproduce the diagnostic locally. Setting the code highlighting to none instead of nasm to hopefully get the bot stumbling back towards green.
