It is also not supported by any backend other than the LLVM backend. 2025-07-25T11:21:28+00:00 bjorn3 17426603+bjorn3@users.noreply.github.com 2025-07-25T09:42:18+00:00 urn:sha1:fe2eeabe27ce3d5b871ab903e65b4707ad015764 2025-07-24T12:50:26+00:00 bors bors@rust-lang.org 2025-07-24T12:50:26+00:00 urn:sha1:5d22242a3a84a55be2f648a94eecff58887547f4 Various refactors to the LTO handling code (part 2) Continuing from https://github.com/rust-lang/rust/pull/143388 this removes a bit of dead code and moves the LTO symbol export calculation from individual backends to cg_ssa. 2025-07-21T16:54:24+00:00 许杰友 Jieyou Xu (Joe) 39484203+jieyouxu@users.noreply.github.com 2025-07-21T16:54:24+00:00 urn:sha1:5e3eb2512591df0cef52404f0ea4202f58935a54 gpu offload host code generation r? ghost This will generate most of the host side code to use llvm's offload feature. The first PR will only handle automatic mem-transfers to and from the device. So if a user calls a kernel, we will copy inputs back and forth, but we won't do the actual kernel launch. Before merging, we will use LLVM's Info infrastructure to verify that the memcopies match what openmp offloa generates in C++. `LIBOMPTARGET_INFO=-1 ./my_rust_binary` should print that a memcpy to and later from the device is happening. A follow-up PR will generate the actual device-side kernel which will then do computations on the GPU. A third PR will implement manual host2device and device2host functionality, but the goal is to minimize cases where a user has to overwrite our default handling due to performance issues. I'm trying to get a full MVP out first, so this just recognizes GPU functions based on magic names. The final frontend will obviously move this over to use proper macros, like I'm already doing it for the autodiff work. This work will also be compatible with std::autodiff, so one can differentiate GPU kernels.
