NettetLink Time Optimization (LTO) lets the compiler do more optimizations, as it can inline across separate compilation units, and even with system libraries. LTO is enabled by compiling objects files with -flto. The effect of this flag is to emit LTO object files (technically this means emitting bitcode). NettetTo link successfully, additional ifx compiler options are required as in this example: dpcpp -c device.cpp ifx -qopenmp -fsycl host.f90 device.o -lstdc++ -lsycl This works for ifx 2024.1.0 and earlier. In a future release, -qopenmp will not be required. Known Limitations

NettetLink-time optimization(LTO) is a type of program optimization performed by a compiler to a program at link time. Link time optimization is relevant in programming languages that compile programs on a file-by-file basis, and then link those files together (such as Cand Fortran), rather than all at once (such as Java's just-in-time compilation(JIT)).
