Tells the compiler to link only device code. This is a deprecated option that may be removed in a future release. This content is specific to DPC++.
Linux: | -fsycl-link-targets=T1,...,Tn |
Windows: | -fsycl-link-targets=T1,...,Tn |
T |
Is a target triple for the device code. You can specify more than one T. |
OFF |
No link is performed. |
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.
To use this option, you must also specify option fsycl.
You should be familiar with ahead-of-time (AOT) compilation when using this option.
None
The following command-line sequence demonstrates a way to use this option:
dpcpp -fsycl-targets=spir64 -c a.cpp -o a.o dpcpp -fsycl-targets=spir64 -c b.cpp -o b.o dpcpp -fsycl-link-targets=spir64 a.o b.o -o linked.spv aoc linked.spv -o linked.aocx dpcpp -fsycl-add-targets=fpga:linked.aocx a.o b.o -o final.out -lOpenCL -lsycl
