Worth mentioning that these test failures are not new. We've been suppressing them since at least LLVM 13.

Good find, thanks. Yeah, because clspv intentionally doesn't compile all OpenCL functions they're necessarily going to have unresolved external calls. Again, this is intentional on their part. This might resolve itself when the CLC work is complete, but otherwise we might just have to work around those targets in the test targets. Note we already do this for NVPTX:

  # nvptx-- targets don't include workitem builtins
  if( NOT ARG_TRIPLE MATCHES ".*ptx.*--$" )
    add_test( NAME external-calls-${obj_suffix}
      COMMAND ./check_external_calls.sh ${CMAKE_CURRENT_BINARY_DIR}/${obj_suffix} ${LLVM_TOOLS_BINARY_DIR}
      WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} )
  endif()

[libclc] Disable external-calls testing for clspv targets
3b172c6 
These targets don't include all OpenCL builtins, so there will always be
external calls in the final bytecode module.

Fixes llvm#127316.
