--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> 2013-04-02 13:25:12 UTC --- Works for me. Are you sure -lvpx doesn't contain LTO bytecode? Can you reproduce it with -r -nostdlib? Please provide the output of appending -v to the link line - also look for the inputs to the WPA stage (the lto1 command with -fwpa, there is a response file at the end, save it with -save-temps and inspect it - there are all objects with LTO bytecode listed).
