  Given the recent change with adding the scheduler pipeline descriptions,
many scan-dump failures emerged. Relax the expected assembler output
conditions on the affected tests to reduce noise.

I'm not entirely sure yet about relaxing the scans like this.
There seem to be uarchs that want to minimize vsetvls under all
circumstances while others don't seem to care all that much.  We could
(not must) assume that the tests that now regress have been written
with this minimization aspect in mind and that we'd want to be sure
that we still manage to emit the minimal number of vsetvls.

Why is the new upper bound acceptable?  What if a vector_load cost
of 12 (or so) causes even more vsetvls?  The 6 in generic_ooo is more
or less arbitrary chosen.

My suggestion before was to create another sched model that has
load costs like before and run the regressing tests with that
model.  That's of course also not really ideal and actually
shoehorned a bit, in particular as no scheduling also increases
the number of vsetvls.

Juzhe: What's your intention with those tests?  I'd suppose you
want the vsetvl number to be minimal here and not higher?  Did you
plan to add a particular scheduling model or are you happy with
the default (all 1) latencies?

Regards

If the scheduling model increases the vsetvls, we shouldn't set it as default scheduling model

I don't think it's that simple.  On some uarchs vsetvls are nearly free 
while on others they can be fairly expensive.  It's not clear (to me) 
yet if one approach or the other is going to be the more common.

That's uarch dependent which is not the stuff I am talking about.
What's I want to say is that this patch breaks those testcases I added for VSETVL PASS testing.
And those testcases are uarch independent.

No, uarch impacts things like latency, which in turn impacts scheduling, 
which in turn impacts vsetvl generation/optimization.

Ya, and I think that's just what's expected for this sort of approach.  
Edwin and I were working through that possibility in the office earlier, 
but we didn't have the code up.  So I figured I'd just go through one in 
more detail to see if what we were talking about was sane.  Grabbing 
some arbitrary function in the changed set:

    void
    test_vbool1_then_vbool64(int8_t * restrict in, int8_t * restrict out) {
        vbool1_t v1 = *(vbool1_t*)in;
        vbool64_t v2 = *(vbool64_t*)in;
    
        *(vbool1_t*)(out + 100) = v1;
        *(vbool64_t*)(out + 200) = v2;
    }

we currently get (from generic-ooo)

    test_vbool1_then_vbool64:
            vsetvli a4,zero,e8,m8,ta,ma
            vlm.v   v2,0(a0)
            vsetvli a5,zero,e8,mf8,ta,ma
            vlm.v   v1,0(a0)
            addi    a3,a1,100
            vsetvli a4,zero,e8,m8,ta,ma
            addi    a1,a1,200
            vsm.v   v2,0(a3)
            vsetvli a5,zero,e8,mf8,ta,ma
            vsm.v   v1,0(a1)
            ret

but we could generate correct code with 2, 3, or 4 vsetvli instructions 
depending on how things are scheduled.  For example, with 
-fno-schedule-insns I happen to get 3

    test_vbool1_then_vbool64:
            vsetvli a5,zero,e8,mf8,ta,ma
            vlm.v   v1,0(a0)
            vsetvli a4,zero,e8,m8,ta,ma
            vlm.v   v2,0(a0)
            addi    a3,a1,100
            addi    a1,a1,200
            vsm.v   v2,0(a3)
            vsetvli a5,zero,e8,mf8,ta,ma
            vsm.v   v1,0(a1)
            ret

because the load/store with the same vcfg end up scheduled back-to-back.  
I don't see any reason why something along the lines of

    test_vbool1_then_vbool64:
            vsetvli a4,zero,e8,m8,ta,ma
            vlm.v   v2,0(a0)
            addi    a3,a1,100
            vsm.v   v2,0(a3)
            vsetvli a5,zero,e8,mf8,ta,ma
            vlm.v   v1,0(a0)
            addi    a1,a1,200
            vsm.v   v1,0(a1)
            ret

wouldn't be correct (though I just reordered the loads/stores and then 
removed the redundant vsetvlis, so I might have some address calculation 
wrong in there).  The validity of removing a vsetvli depends on how the 
dependant instructions get scheduled, which is very much under the 
control of the pipeline model -- it's entirely possible the code with 
more vsetvlis is faster, if vsetvli is cheap and scheduling ends up 
hiding latency better.

So IMO it's completely reasonable to have vsetvli count ranges for a 
test like this.  I haven't looked at the others in any detail, but I 
remember seeing similar things elsewhere last time I was poking around 
these tests.  We should probably double-check all these and write some 
comments, just to make sure we're not missing any bugs, but I'd bet 
there's a bunch of valid testsuite changes.

Like we talked about in the call this morning we should probably make 
the tests more precise, but that's a larger effort.  After working 
through this I'm thinking it's a bit higher priority, though, as in this 
case the bounds are so wide we're not even really testing the pass any 
more.

I suggest specify -fno-schedule-insns to force tests assembler never change for any scheduling model.

We already do that and that's the point - as I mentioned before, no
scheduling is worse than default scheduling here (for some definition
of worse).  The way to reduce the number of vsetvls is to set the
load latency to a low value.

I think -fno-schedule-insns is a perfectly reasonable way to get rid of 
the test failures in the short term.

Using -fno-schedule-insns doesn't really fix the core fragility of the 
tests, though: what the pass does depends very much on the order of 
instructions it sees, so anything that reorders RTL is going to cause 
churn in the tests.  Sure getting rid of scheduling will get rid of a 
big cause for reordering, but any pass could reorder RTL and thus change 
the expected vsetvl counts.

Maybe the right thing to do here is to rewrite these as RTL tests?  That 
way we can very tightly control the input ordering.  It's kind of the 
opposite of Jeff's suggestion to add more debug output to the pass, but 
I think that wouldn't actually solve the issue: we're not having trouble 
matching assembly, the fragility comes from the input side.

That might be a "grass is always greener" thing, though, as I don't 
think I've managed to write a useful RTL test yet...
