Multiple extensions may be specified, separated by a @code{+}. The
extensions should be specified in ascending alphabetical order.
+Some extensions may be restricted to particular architectures; this is
+documented in the list of extensions below.

Extension mnemonics may also be removed from those the assembler accepts.
This is done be prepending @code{no} to the option that adds the extension.
Extensions that are removed should be listed after all extensions which have
