1Control default initialization of stack variables in C and C++ code. 2Options other than 3.Li none 4require the Clang compiler or GCC 12.0 or later. 5The default value is 6.Li none . 7Valid values are: 8.Bl -tag -width indent 9.It Li none 10Do not initialize stack variables (standard C/C++ behavior). 11.It Li pattern 12Build the base system or kernel with stack variables initialized to 13.Pq compiler defined 14debugging patterns on function entry. 15.It Li zero 16Build the base system or kernel with stack variables initialized 17to zero on function entry. 18This value is converted to 19.Li none 20for amd64 kernel builds due to incompatability with ifunc memset. 21.El 22
