Hi,
My function is working properly for the below case -
for (i = 1; i < N ; i++)
{
a[i] = 1;
}
for (i = 1; i < N ; i++)
{
j = a[i];
}
But I am required to add additional phi node for j in the following case -
for (i = 1; i < N ; i++)
{
a[i] = 1;
}

The function replace_uses_by() also does the same renaming and it is

Hi,
Consider 2 for loops as given below.
for (i = 1; i < N ; i++)
{
a[i] = 1;
}
for (i = 1; i < N ; i++)
{
j = j + a[i];
}
Their corresponding GIMPLE code looks like.
loop_2 (header = 6, latch = 7, niter = , upper_bound = 999, estimate = 999)
{

Hi,
Consider the 2 for loops given below.
for (i = 0; i < N ; i++)
{
a[i]= 1;
}
for (i = 0; i < N ; i++)
{
j = j+a[i];
}
The headers of these 2 loops are bb_3, bb_6 respectively. They are as follows.
bb_3 (preds = {bb_4 bb_2 }, succs = {bb_4 bb_5 })

Hi,
I have transferred all the statements of one BB( header of one loop)
to another BB. After that I have updated SSA information too.
But I get this error-
definition in block 6 does not dominate use in block 3
for SSA_NAME: i_25 in statement:
# VUSE
D.1189_10 = a[i_25];
loop.c:8: internal com
Hi Zdenek,
Thanks.
Sandeep.

Hi,
The error is rectified. The bug is in the function that calls fuse_loops().
Now I am trying to transfer all the statements, using code -
/* The following function fuses two loops. */
void
fuse_loops (struct loop *loop_a, struct loop *loop_b)
{
debug_loop (loop_a, 10);
debug_loop (loop_b,

Hi Zdenek,
I have written this function
/* The following function fuses two loops. */

Hi,
I am trying to fuse two loops in tree level. For that, I am trying to
transfer statements in the header of one loop to the header of the
other one.
The code " http://rafb.net/p/fha0IG57.html " contains the 2 loops.
After moving a statement from one BB to another BB, do I need to
update any
