Windows: | -fsycl-link-targets=T1,...,Tn

## Arguments

T | Is a target triple for the device code. You can specify more than one T.

## 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.

To use this option, you must also specify option fsycl.

### Note

## Alternate Options

None

## Example

The following command-line sequence demonstrates a way to use this option:

    dpcpp -fsycl-targets=spir64-unknown-linux-sycldevice -c a.cpp -o a.o
    dpcpp -fsycl-targets=spir64-unknown-linux-sycldevice -c b.cpp -o b.o
    dpcpp -fsycl-link-targets=spir64-unknown-linux-sycldevice 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
