------- Comment #2 from rguenth at gcc dot gnu dot org 2008-04-18 14:22 -------
Shorter testcase:
struct Loc { int x[2]; };
int foo (int i, int b)
{
struct Loc IND;
if (b)
{
IND.x[0] = i;
IND.x[1] = 0;
}
else
{
IND.x[0] = i;
IND.x[1] = 1;
}
return IND.x[0];
}
this breaks during PHI translation where the oracle is not properly used.

Huhm. This is just because PRE and SCCVN are disconnected and use their own
IL.
Maybe finally time to fix this...

While not really useful, i dare to state that SCC(N)-VN unfortunately misses a
lot of what it is ment to serve (IMHO), generally:
1) PR11832
testcase from http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11832#c0
Needs adjustment (looked into it -- AFAICR -- befor 4.3 was branched; didn't
retry after you recently touching SCCVN, i admit)
2) PR5738
The testcase from http://gcc.gnu.org/bugzilla/show_bug.cgi?id=5738#c0
is completely undiagnosed (and _severely_ mishandled -- IMHO) by current SCCVN.
This one is particularly mean since you may run into dominator related pitfalls
very, very fast, from what i've seen (before you touched tree-ssa-pre,
admitteldy).
A couple of sensible and nice improvements are mentioned in ¹) above.

These are both testcases for missed code-motion which neither PRE nor
FRE performs. While SCCVN can figure out that two stmts compute the
same value it still needs a pass that makes use of it ;)

------- Comment #8 from rguenth at gcc dot gnu dot org 2008-08-17 10:20 -------
Hm, I have a patch that makes PRE phi-translation use the oracle, but still
the testcase is not optimized because for
struct Loc { int x[1]; };
int foo (int i, int b)
{
struct Loc IND;
if (b)
IND.x[0] = i;
else
IND.x[0] = i;
return IND.x[0];
}
PRE doesn't do anything either (instead this case looks like something
FRE can handle with the patch I have for PR23094).
But the patch handles
struct Loc { int x[2]; };
int foo (int i, int j, int b)
{
struct Loc IND;
if (b)
{
IND.x[0] = i;
IND.x[1] = 1;
}
else
{
IND.x[0] = j;
IND.x[1] = 0;
}
return IND.x[0];
}
I suspect that the original testcase was handled by DOM, which also lacks
support from the alias-oracle. Hmm, checking with 4.3 it doesn't do anything
for the testcase - not even the PRE opportunity for IND.x[2]. So
eventually this was something done by LIM, as the testcase was placed
inside a loop? ...

In theory elminate should handle these case, but even though phi-translation
reveals that the value of the load is available in bb 5 we do not update
avail-out if we do not end up doing an insertion.

And I have a patch to fix regular insertion. Which means PRE now produces
foo (int i, int j, int k, int b)
{
int prephitmp.12;
int pretmp.11;

if (b_1(D) != 0)
goto <bb 3>;
else
goto <bb 4>;
<bb 3>:
IND.x[0] = i_2(D);
IND.x[1] = j_3(D);
D.1916_5 = k_4(D) + -1;
IND.x[2] = D.1916_5;
goto <bb 5>;
<bb 4>:
IND.x[0] = i_2(D);
IND.x[1] = j_3(D);
IND.x[2] = k_4(D);
<bb 5>:
# prephitmp.12_20 = PHI <D.1916_5(3), k_4(D)(4)>
D.1919_6 = i_2(D);
D.1920_7 = j_3(D);
D.1922_9 = prephitmp.12_20;
D.1921_8 = D.1920_7 + D.1919_6;
D.1918_10 = D.1921_8 + D.1922_9;
return D.1918_10;
}
for the original testcase.
