Hi, Sebastian,
Thanks for your explanation.
Our goal is to deprecate the GCC extension on structure containing a flexible
array member not at the end of another structure. In order to achieve this
goal, we provided the warning option -Wflex-array-member-not-at-end for the
users to
locate all such cases in their source code and update the source code to
eliminate such cases.
What is the benefit of deprecating this GCC extension? If GCC extensions
are removed, then it would be nice to enable the associated warnings by
default.
The static initialization of structures with flexible array members will still
work as long as the flexible array members are at
the end of the structures.
Removing the support for flexible array members in the middle of
compounds will make the static initialization practically infeasible.
My question: is it possible to update your source code to move the structure
with flexible array member to the end of the
containing structure?
i.e, in your example, in the struct Thread_Configured_control, move the field
“Thread_Control Control” to the end of the structure?
If we move the Thread_Control to the end, how would I add a
configuration defined number of elements at the end?
