It looks like this was fixed by Michael Matz here:
http://gcc.gnu.org/ml/gcc-patches/2007-08/msg01978.html
This patch was added to gcc-4.3, and the gcc-4.2 branch is closed, so I think
this bug should be closed resol

You can't have if-converted stores at the tree level.
Forms of store motion, like the example of comment #2, ought to get implemented
at the tree level somewhen, though. AFAIU this is currently very hard to do,
but

Yes this is true. The example I posted was a simplest case where it fails.
Below mmight be a typical case where you have to do two stores.
int cmov(int* A ,int B ,int C ,int* D ,int* E ,int F ,int g) {
int k

The other way of getting this is to have the code converted so there is only
one store instead of two:
int cmov(int* A ,int B ,int C ,int* D ,int* E ,int F ,int g) {
int k,f;
for (k = 1; k <= 1000; k++) {

Confirmed, if cvt should have a way to track if a memory write has happened.
