Bug ID: 125190
Summary: Stale documentation of __stack_chk_guard
Product: gcc
Version: 16.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libgcc
Assignee: unassigned at gcc dot gnu.org

Target Milestone: ---
Documentation of __stack_chk_guard
@deftypefn {Target Hook} tree TARGET_STACK_PROTECT_GUARD (void)
This hook returns a @code{DECL} node for the external variable to use
for the stack protection guard. This variable is initialized by the
runtime to some random value and is used to initialize the guard value
that is placed at the top of the local stack frame. The type of this
variable must be @code{ptr_type_node}.
The default version of this hook creates a variable called
@samp{__stack_chk_guard}, which is normally defined in @file{libgcc2.c}.
