Since new headergen is now the default for building LLVM-libc, the docs
need to be updated to reflect that. While I was editing those docs, I
took a quick pass at updating other out-of-date pages.
Summary:
I forgot that the OpenMP tests still look for this, reverting for now
until I can make a fix.
This reverts commit c1c6ed83e9ac13c511961e5f5791034a63168e7e.
Summary:
Previously, the GPU built the `libc` in a fat binary version that was
used to pass this to the link job in offloading languages like CUDA or
OpenMP. This was mostly required because NVIDIA couldn't consume the
standard static library version. Recent patches have now created the
`clang-nvlink-wrapper` which lets us do that. Now, the C library is just
included implicitly by the toolchain (or passed with -Xoffload-linker
-lc).
This code can be fully removed, which will heavily simplify the build
(and removed some bugs and garbage files I've encoutnered).
Summary:
After the overhaul of the GPU build the documentation pages were a
little stale. This updates them with more in-depth information on
building the GPU runtimes and using them. Specifically using them goes
through the differences between the offloading and direct compilation
modes.
