(In reply to comment #2)
> they appear after 40.flow2 for some reason.

The some reason is that they are prologue/epologue code.

Testcase:

void bar (float *pa, float *pb, float *pc)
{
  int i;
  for (i = 0; i < 256; i++)
{
}
}
main1 (int n)
{
  int i;
  float a[256] __attribute__ ((__aligned__(16))); float b[256] __attribute__
((__aligned__(16))) =
{0,3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54,57}; float c[256]
__attribute__ ((__aligned__(16))) =
{0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19};
  float *pa = a;
  float *pb = b;
  float *pc = c;
  for (i = 0; i < n; i++)
{
  pa[i] = pb[i] * pc[i];
}
  bar (pa,pb,pc);
}

last rtl dump of main (43.ce3) shows:

(insn 340 339 341 0 (parallel [
(set (reg:SI 109 vrsave)
(unspec_volatile:SI [
(reg:SI 0 0)
(reg:SI 109 vrsave)
] 30))
(clobber (reg:V4SI 77 0))
(clobber (reg:V4SI 78 1))
(clobber (reg:V4SI 90 13))
]) -1 (nil)
(expr_list:REG_DEAD (reg:SI 0 0)
(expr_list:REG_UNUSED (reg:V4SI 90 13)
(expr_list:REG_UNUSED (reg:V4SI 78 1)
(expr_list:REG_UNUSED (reg:V4SI 77 0)
(nil))

they appear after 40.flow2 for some reason.
