------- Comment #14 from rguenth at gcc dot gnu dot org  2010-09-18 18:25 
You have way more non-SSA variables - possibly due to callee-copy of args

I suppose some optimizations end up being disabled for some reason by that,
but likely nobody will be interested to fixup missed optimizations for
this target :/

So - if you are interested (heh ...) I'd start comparing dumps to i?86 dumps
and see where they start to diverge badly.  Also try and see why you end up

  complex double cd.1;
  complex long double cld.0;

not in SSA form:

  REALPART_EXPR <cld.0> = cld$real_19;
  IMAGPART_EXPR <cld.0> = cld$imag_20;
  REALPART_EXPR <cd.1> = cd$real_10;
  IMAGPART_EXPR <cd.1> = cd$imag_11;
  REALPART_EXPR <cd.1> =  Inf;

on i?86 I never even start having partial definitions of these on the lhs ...
(but I also do not have the callee-copy, so you might check if SRA makes
those partial defs from them by trying with -fno-tree-sra).

If you're not interested I suggest to XFAIL the testcase for the failing
