            Bug ID: 25602
           Summary: Unclear documentation about .altmacro
           Product: binutils
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gas
          Assignee: unassigned at sourceware dot org
          Reporter: sergey.belyashov at gmail dot com
  Target Milestone: ---

1. .altmacro documentation has no any examples. But usage of %expr is unclear
(it is hard to understand, that it works for macro arguments).
2. There is no information about ampersand symbol, which can be used as
delimiter in the macro (present in the .macro documentation). But how to do
bitwise AND inside macro (backslash and exclamation does not work as
escapes)?!? Go..le does not know it.
