Summary:
All of these are functionally the same code, just compiled for separate
architectures. We currently do not expose a way to execute these on
separate architectures as the host plugin works using `dlopen` into the
same process, and therefore cannot possibly be an incompatible
architecture. (This could work with a remote plugin, but this is not
supported yet).
This patch simply renames all of these to the same thing so we no longer
need to check around for its varying definitions.
Summary:
This call was removed a few months ago to allow the runtime to actually
init / deinit in a correct order. However that patch forgot to remove a
few leftover uses.
Summary:
The move from `openmp` to `offload` did not preserve the per-target
runtime directory installation. This is important because this
per-target directory is always included first and is likely the de-facto
way to handle these going forward. Without this installation, old
installations of the library will be linked against first.
In a nutshell, this moves our libomptarget code to populate the offload
subproject.
With this commit, users need to enable the new LLVM/Offload subproject
as a runtime in their cmake configuration.
No further changes are expected for downstream code.
Tests and other components still depend on OpenMP and have also not been
renamed. The results below are for a build in which OpenMP and Offload
are enabled runtimes. In addition to the pure `git mv`, we needed to
adjust some CMake files. Nothing is intended to change semantics.
```
ninja check-offload
```
Works with the X86 and AMDGPU offload tests
```
ninja check-openmp
```
Still works but doesn't build offload tests anymore.
```
ls install/lib
```
Shows all expected libraries, incl.
- `libomptarget.devicertl.a`
- `libomptarget-nvptx-sm_90.bc`
- `libomptarget.rtl.amdgpu.so` -> `libomptarget.rtl.amdgpu.so.18git`
- `libomptarget.so` -> `libomptarget.so.18git`
