------- Additional Comments From pinskia@physics.uc.edu 2003-06-05 15:35 -------
It is still happens on the mainline (20030604) but it infacts adds an extra load on the one
with the optimization field that is not need. It removes a jump though so the mainline will
be faster than 3.3 because of that.
without the optimization field:
.L18:
addl (%eax), %ecx #, c
addl $4, %eax #, tmp108
movl %eax, 4(%ebx) # tmp108, <variable>._M_current
.L5:
movl 4(%ebx), %eax #, tmp96
cmpl %edx, %eax # <variable>._M_finish, tmp96
jne .L18 #,
with the optimization field
.L18:
movl (%eax), %edx #* <variable>._M_start, <-- extra load
addl $4, %eax #, <variable>._M_start
addl %edx, %ebx #, c
.L5:
cmpl %ecx, %eax # <variable>._M_finish, <variable>._M_start
jne .L18 #,

This looks like an other putting objects on the stack too soon, putting target milestone to
the tree-ssa.

Related to PR 8781, really it is close enough related to PR 8781 that I am going to mark
this on to depend on PR 8781.

Actually this is not related to bug 8781 at all but rather 2399, the problem is now the
struct contain other structs so causing SRA not to happen.

Ought to be handled by SRA now, but dom1 isn't cleaning up the code enough.
