Summary: These functions provide special-case implementations internal to the OpenMP device runtime. This can potentially conflict with the symbols pulled in from the actual GPU `libc`. This patch makes these weak, so in the case that the GPU libc functions exist they will be overridden. This should not impact performance in the average case because the old `-mlink-builtin-bitcode` version does internalization, deleting weak, and the new LTO path will resolve to the strong reference and then internalize it.
The LLVM/Offload Subproject
The Offload subproject aims at providing tooling, runtimes, and APIs that allow users to execute code on accelerators or other "co-processors" that may or may not match the architecture of their "host". In the long run, all kinds of targets are in scope of this effort, including but not limited to: CPUs, GPUs, FPGAs, AI/ML accelerators, distributed resources, etc.
The project is just starting and the design is still not ironed out. More content will show up here and on our webpage soon. In the meantime people are encouraged to participate in our meetings (see below) and check our development board as well as the discussions on Discourse.
