URL: https://github.com/llvm/llvm-project/commit/69a77771a9f5e577083338c3cebd61bbeb417843 DIFF: https://github.com/llvm/llvm-project/commit/69a77771a9f5e577083338c3cebd61bbeb417843.diff LOG: [OpenMP] Make linker wrapper thin-lto default thread count use all Summary: Currently there is no option to configure the number of thin-backend threads to use when performing thin-lto on the device, but we should default to use all the threads rather than just one. In the future we should use the same arguments that gold / lld use and parse it here.
