Summary: There is currently effort to change over the default AMDGPU code object version llvm#65410. However, this unfortunately causes problems in the LLVM LibC test suite that leads to a hang while executing. This is most likely a bug to do with indirect call optimization, as it can be avoided without optimizations or with manually preventing inlining in the AMDGPU startup code. This patch sets the AMDGPU code object version to be four explicitly on the LibC test suite. This should unblock the efforts to move the default to 5 without breaking the test suite. This isn't a great solution, but there is currently some time pressure to get COV5 landed and this seems to be the easiest solution.

Summary: There is currently effort to change over the default AMDGPU code object version llvm#65410. However, this unfortunately causes problems in the LLVM LibC test suite that leads to a hang while executing. This is most likely a bug to do with indirect call optimization, as it can be avoided without optimizations or with manually preventing inlining in the AMDGPU startup code. This patch sets the AMDGPU code object version to be four explicitly on the LibC test suite. This should unblock the efforts to move the default to 5 without breaking the test suite. This isn't a great solution, but there is currently some time pressure to get COV5 landed and this seems to be the easiest solution.
