1 Control default initialization of stack variables in C and C++ code.
4 require the Clang compiler or GCC 12.0 or later.
10 Do not initialize stack variables (standard C/C++ behavior).
12 Build the base system or kernel with stack variables initialized to
14 debugging patterns on function entry.
16 Build the base system or kernel with stack variables initialized
17 to zero on function entry.
18 This value is converted to
20 for amd64 kernel builds due to incompatability with ifunc memset.
