--- Comment #10 from Georg-Johann Lay <gjl at gcc dot gnu.org> 2011-05-17 18:57:39 UTC --- Created attachment 24264 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=24264 Proposed patch. Proposed Patch (also compatible with older versions of GCC). The insn needs at most 3 instructions and does not put pressure on d-regs. * config/avr/avr.md ("*extzv"): New insn.
