Default

Description
This option enables the control flow protection mechanism. It tells the
compiler to analyze control flow of valid targets for indirect calls and
inserts a call to a checking routine before each indirect call to verify the
target of the given indirect call.
The
/guard:cf
option must be passed to both the compiler and
linker.
Code compiled using
/guard:cf
can be linked to libraries and object files that are
not compiled using the option.
This option has been added for Microsoft compatibility. It uses the
Microsoft implementation.
This option only applies to host compilation. When
offloading is enabled, it does not impact device-specific compilation.
