            Bug ID: 85619
           Summary: Inconsistent descriptions for new warning options in
                    GCC 8.1.0
           Product: gcc
           Version: 8.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: julien at trigofacile dot com
  Target Milestone: ---

In GCC 8.1.0 documentation
(https://gcc.gnu.org/onlinedocs/gcc-8.1.0/gcc/Warning-Options.html):

1/ -Wif-not-aligned is said to be included by default in documentation, but
Release Changes mention its inclusion in -Wall.  So, is it really the case? 
(Also note a typo "This is is enabled by default." in documentation.)

2/ -Wstringop-truncation and -Wpacked-not-aligned are said to be included in
-Wall in Release Changes but documentation does not mention them in -Wall.
