[Bug middle-end/36099] [4.4 Regression] early loop unrolling pass prevents vectorization, SLP doesn't do its job

[rguenth at gcc dot gnu dot org]

------- Comment #2 from rguenth at gcc dot gnu dot org  2008-05-02 12:46 -------
The vectorizer doesn't know to vectorize __builtin_cexpi or
{REAL,IMAG}PART_EXPR
either.

IMHO rather than somehow tweaking the early unroller the vectorizer should
know how to deal with complex types.
