AMDGPU: Default to hidden visibility Object linking isn't supported, so it's not useful to emit default visibility. Default visibility requires relocations we don't yet support for functions compiled in another translation unit. WebAssembly already does this, although they insert these arguments in a different place for some reason. llvm-svn: 341033

AMDGPU: Teach toolchain to link rocm device libs Currently the library is separately linked, but this isn't correct to implement fast math flags correctly. Each module should get the version of the library appropriate for its combination of fast math and related flags, with the attributes propagated into its functions and internalized. HIP already maintains the list of libraries, but this is not used for OpenCL. Unfortunately, HIP uses a separate --hip-device-lib argument, despite both languages using the same bitcode library. Eventually these two searches need to be merged. An additional problem is there are 3 different locations the libraries are installed, depending on which build is used. This also needs to be consolidated (or at least the search logic needs to deal with this unnecessary complexity).

Add -fapply-global-visibility-to-externs for -cc1 Introduce an option to request global visibility settings be applied to declarations without a definition or an explicit visibility, rather than the existing behavior of giving these default visibility. When the visibility of all or most extern definitions are known this allows for the same optimisations -fvisibility permits without updating source code to annotate all declarations.
