[Bug target/26515] peephole2 causes unrecognized insn, zero_extending non-general register



------- Comment #1 from hp at gcc dot gnu dot org  2009-10-12 04:10 -------
Created an attachment (id=18784)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=18784&action=view)
patch and testcase from PR39765

Patch won't apply cleanly to gcc-4.3; apply s/CRIS_CONST/CONST/.
Also, the test-case doesn't trig on gcc-4.3-branch, just 4.4.
(Main trunk soon.)
