47 * GCS specific errors (those reported with EC 0x2d) will be reported as
56 in LR match those in the GCS, the LR will be ignored. This is not supported

82 status of the specified GCS mode bits will be rejected.

106 * It should be noted that since enabling GCS will result in GCS becoming
109 usage will be that GCS is enabled very early in execution of a program.
116 * When GCS is enabled for a thread a new Guarded Control Stack will be
121 new Guarded Control Stack will be allocated for the new thread with
125 the top 8 bytes of the stack will be initialised to 0 and GCSPR_EL0 will
126 be set to point to the address of this 0 value, this can be used to
129 * Additional Guarded Control Stacks can be allocated using the
134 SHADOW_STACK_SET_TOKEN is specified a cap will be placed on the stack,
135 if SHADOW_STACK_SET_MARKER is not specified the cap will be the top 8
136 bytes of the stack and if it is specified then the cap will be the next
141 multiple of 8 bytes larger than 8 bytes and must be 8 bytes aligned.
143 * An address can be specified to map_shadow_stack(), if one is provided then
144 it must be aligned to a page boundary.
147 that thread will be freed. Note carefully that if the stack has been
148 switched this may not be the stack currently in use by the thread.

165 GCS cap token will be written to the GCS, this is an architectural GCS cap
172 return handler will be pushed onto the GCS, allowing return from the signal

198 signal return will be rejected.
207 * The GCS mode, including enable and disable, may be configured via ptrace.
208 If GCS is enabled via ptrace no new GCS will be allocated for the thread.
216 * NT_ARM_GCS notes will be added to each coredump for each thread of the
