Motivation / Problem
GCC11 generates warnings like these:
Description
Use
__attribute__
access none to specify that arguments pointing at buffer end are never dereferenced.Limitations
__has_attribute
cannot be utilized becausenone
is recently added option toaccess
attribute.Pre-release GCC11.0 builds will also generate this warning, but it cannot be included in version check as early GCC11.0 builds didn't know about
none
option. (thus this PR checks for >11.1 release)Checklist for review
Some things are not automated, and forgotten often. This list is a reminder for the reviewers.
