<br>
We're seeing this failed assertion with this patch:<br>
<br>
opt: ../lib/Analysis/MemorySSA.cpp:1983: void<br>
llvm::MemorySSA::verifyOrdering(llvm::Function &) const: Assertion `AL-<br>
>size() == ActualAccesses.size() && "We don't have the same number of<br>
accesses in the block as on the " "access list"' failed.<br>
<br>
when we do<br>
<br>
opt -S -o - mem.ll -disable-basicaa -loop-rotate<br>
<br>
Just looking quickly in the debugger I see<br>
<br>
(gdb) p AL->size()<br>
$1 = 4<br>
(gdb) p ActualAccesses.size()<br>
$2 = 3<br>
<br>
I originally found this running fuzz tests with random comiler flags<br>
for my out-of-tree target, then I've bugpoint reduced the input and<br>
tried to reproduce it on trunk as well, so the input might be weird,<br>
but hopefully it's possible to make something out of it anyway.<br>
