Subject: Don't forget to add the declaration of our temporary variable for assigns.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ae805922b7e3cdaf3aee26c3b799fe3608669bba;p=mesa.git

Don't forget to add the declaration of our temporary variable for assigns.

Otherwise, dead code elimination gets confused since it relies on
seeing decls.
