From be51689e5e0090bf4d816efb885dd9b31f2d8273 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Tue, 25 Aug 2020 16:14:38 -0700 Subject: [PATCH] Documentation/llvm: Improve formatting of commands, variables, and arguments While reviewing a separate patch, I noticed that the formatting of the commands, variables, and arguments was not in a monospaced font like the rest of the Kbuild documentation (see kbuild/kconfig.rst for an example). This is due to a lack of "::" before indented command blocks and single backticks instead of double backticks for inline formatting. Add those so that the document looks nicer in an HTML format, while not ruining the look in plain text. As a result of this, we can remove the escaped backslashes in the last code block and move them to single backslashes.
