[Bug 1878760] Re: gcc-10 is selecting amdgcn target by default

[chinoune]

Binaries built for different gpu architectures are not compatible.
So installing gcc-10-offload-amdgcn will just make gcc build binaries for amdgcn target which can't run on nvptx target.

Title:
  gcc-10 is selecting amdgcn target by default

Status in gcc-10 package in Ubuntu:
  Confirmed

Bug description:
  While trying to offload some programs to my laptop nvidia gpu, compilation failed because gcc-10 is selecting amdgcn target by default even my laptop has not any amd graphics.
  A workaround is to use "-foffload=nvptx-none=other-flags".

  Ubuntu 20.04 x86_64
