hintonda added a comment.

Here are a few examples from existing tests showing how this option could be used:

  -Xclang -analyzer-max-loop -Xclang 34

becomes:

  -Wc,-analyzer-max-loop,34
  
  -Xclang -analyzer-checker=debug.ConfigDumper -Xclang -analyzer-max-loop -Xclang 34

becomes:

  -Wc,-analyzer-checker,debug.ConfigDumper,-analyzer-max-loop,34
  
  -Xclang -analyzer-config -Xclang path-diagnostics-alternate=true -Xclang -analyzer-output=plist

becomes:

  -Wc,-analyzer-config,path-diagnostics-alternate=true,-analyzer-output=plist
  
  -Xclang -internal-isystem -Xclang /tmp/

becomes:

  -Wc,-internal-isystem,/tmp/
  
  -Xclang -internal-externc-isystem -Xclang /tmp

becomes:

  -Wc,-internal-externc-isystem,/tmp
  
  -Xclang -main-file-name -Xclang foo.c

becomes:

  -Wc,-main-file-name,foo.c
  
  -Xclang -include-pch -Xclang %t.pch

becomes:

  -Wc,-include-pch,%t.pch
  
  -Xclang -fdisable-module-hash -Xclang -detailed-preprocessing-record -Xclang -verify

becomes:

  -Wc,-fdisable-module-hash,-detailed-preprocessing-record,-verify
