Mixing -fcf-protection and -fcf-protection=none objects are allowed.
Linker just merges -fcf-protection values from all input objects.
Add -fcf-protection=check for the final link with LTO. An error is
issued if LTO object files are compiled with different -fcf-protection
values. Otherwise, -fcf-protection=check is ignored at the compile
time. Without explicit -fcf-protection at link time, -fcf-protection
values from LTO object files are merged at the final link.

This was first submitted many years ago
https://gcc.gnu.org/ml/gcc-patches/2010-10/msg02468.html
The command line option -fcallgraph-info is added and makes the
compiler generate another output file (xxx.ci) for each compilation
unit (or LTO partitoin), which is a valid VCG file (you can launch
your favorite VCG viewer on it unmodified) and contains the "final"
callgraph of the unit. "final" is a bit of a misnomer as this is
actually the callgraph at RTL expansion time, but since most
high-level optimizations are done at the Tree level and RTL doesn't
usually fiddle with calls, it's final in almost all cases. Moreover,
the nodes can be decorated with additional info: -fcallgraph-info=su
adds stack usage info and -fcallgraph-info=da dynamic allocation info.

https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf
A proposal is to introduce a target independent flag
-fcf-protection=[none|branch|return|full] with a semantic to
instrument a code to control validness or integrity of control-flow
transfers using jump and call instructions. The main goal is to detect
and block a possible malware execution through transfer the execution
to unknown target address. Implementation could be either software or
target based. Any target platforms can provide their implementation
for instrumentation under this option.
The compiler should instrument any control-flow transfer points in a
program (ex. call/jmp/ret) as well as any landing pads, which are
targets of control-flow transfers.
A new 'nocf_check' attribute is introduced to provide hand tuning
support. The attribute directs the compiler to skip a call to a
function and a function's landing pad from instrumentation. The
attribute can be used for function and pointer to function types,
otherwise it will be ignored.
Currently all platforms except i386 will report the error and do no
instrumentation. i386 will provide the implementation based on a
specification published by Intel for a new technology called
Control-flow Enforcement Technology (CET).

This adds an -freorder-blocks-algorithm=[simple|stc] flag, with "simple"
as default. For -O2 and up (except -Os) it is switched to "stc" instead.
Targets that never want STC can override this. This changes -freorder-blocks
to be on at -O1 and up (was -O2 and up).
In effect, the changes are for -O1 (which now gets "simple" instead of
nothing), -Os (which now gets "simple" instead of "stc", since STC results
in much bigger code), and for targets that wish to never use STC (not in
this patch though).
