Control default initialization of stack variables in C and C++ code. Options other than .Li none require the Clang compiler or GCC 12.0 or later. The default value is .Li none . Valid values are: .Bl -tag -width indent .It Li none Do not initialize stack variables (standard C/C++ behavior). .It Li pattern Build the base system or kernel with stack variables initialized to .Pq compiler defined debugging patterns on function entry. .It Li zero Build the base system or kernel with stack variables initialized to zero on function entry. This value is converted to .Li none for amd64 kernel builds due to incompatability with ifunc memset. .El
