binop-xor3.c.165t.optimized
This test previously passed, now it fails.
A patch in the revision range (last_known_working:first_known_failing)
198890:198899
exposed or caused this regression. Since then it fails as follows:
Running /tmp/hpautotest-gcc0/gcc/gcc/testsuite/gcc.dg/dg.exp ...
FAIL: gcc.dg/binop-xor3.c scan-tree-dump-times optimized "\\^" 1
The files binop-xor3.s and binop-xor3.c.165t.optimized are attached.
Author of the most suspect patch (having touched the actual test-case and
related code) in revision range CC:ed.
Apparently, cris-elf is just one of many targets for which this test now fails;
I guess half of them regressed but x86_64 and i686 (and ia64, sh4, spu), as
seen on gcc-testresults@ since then: s390-ibm-linux-gnu
