Please, add tests for checking the SDL linking. You can take example from an existing one. To make the tests target the HIPSPV toolchain you need to replace --offload-arch=XXX
options with single --offload=spirv64
option.
Co-authored-by: Henry Linjamäki <[email protected]>
* Also ordering and add --no-offloadlib support
* Remove --no-gpuoffload options and tests

LGTM!
Unfortunately, I don't have access rights to approve PRs nor land them. Maybe @yxsamliu can help you with that?
