[Bug 1909805] Re: libclc-amdgcn missing files for current AMD APUs

[Oibaf]

Moved from libclc to llvm-toolchain-14, since the former was removed
from kinetic and the latter now provides libclc.

** Also affects: llvm-toolchain-14 (Ubuntu)
   Importance: Undecided
       Status: New

** Changed in: libclc (Ubuntu)
       Status: Confirmed => Invalid

Title:
  libclc-amdgcn missing files for current AMD APUs

Status in libclc package in Ubuntu:
  Invalid
Status in llvm-toolchain-14 package in Ubuntu:
  New

Bug description:
  I'm finding that the libclc support for current AMD APUs is missing,
  at least for Ryzen 4000 series laptop APUs. when running something
  like `hashcat -b --force`, you get the following:

  clBuildProgram(): CL_BUILD_PROGRAM_FAILURE

  fatal error: cannot open file '/usr/lib/clc/gfx909-amdgcn-mesa-
  mesa3d.bc': No such file or directory

  * Device #1: Kernel /usr/share/hashcat/OpenCL/shared.cl build failed.

  Looking at the package, there's up to gfx906*, so if there's upstream
  support for these APUs, it'd be great to get the support packaged in.
  I'm filing this in the hope we can get this sorted out pre-21.04.
