Default
- OFF
- No link is performed.
Description
This option tells the compiler to link only device code. It is used in a
link step.
It tells the compiler to link device code for the given target triples, and
output multiple linked device code images. It does not produce fat binary.
You should be familiar with ahead-of-time (AOT)
compilation when using this option.
When using the icx/icpx compiler driver for this option, you must also
specify option
-fsycl
.
When using the dpcpp compiler driver, option
-fsycl
is implied by default.
When SYCL offloading is enabled, this option only
applies to device-specific compilation.
