------- Comment #2 from ubizjak at gmail dot com  2008-02-01 08:49 -------
Have a patch for the testsuite. gen-vect-X.c vectorizer testcases should
probably be moved into gcc.dg/vect, at least those that scan for vectorized
loops.

[Bug testsuite/35047] some vectorisation tests fail with --with-arch=core2

[ubizjak at gmail dot com]

------- Comment #6 from ubizjak at gmail dot com  2008-02-04 06:50 -------
The vectorizer failures are due to "target vect_cmdline_needed". We want to
vectorize with generic vectorization (i.e. no SSE), but using --with-arch, SSE
is implied in command line even without -msse2.

gcc.dg/vect/vect-iv-9.c doesn't fail for me. Can you look at the logs, what is
going wrong?

Does darwin need -fomit-frame-pointer for this test?
