My question is, why doesn't tree-ssa-dse.c do anything to the following
code?
Because it does not understand V_MUST_DEF, see PR 18880 for a patch and

Sorry if there is an obvious answer for this, but I'm not to familiar with
the tree-ssa phase.
My question is, why doesn't tree-ssa-dse.c do anything to the following
code?
int i,j,k,l;
void p1() {
i = 1; /* Dead store */
j = 2;
i = k; /* Dead store after copy prop */
if (i == 1)
