+
+    [JumpThreading] Don't restrict cast-traversal to i1
+    
+    Summary:
+    In D17663, JumpThreading learned to look trough simple cast instructions,
+    but only if the source of those cast instructions was a phi/cmp i1
+    (in an effort to limit compile time effects). I think this condition
+    is too restrictive. For switches with limited value range, InstCombine
+    will readily introduce an extra `trunc` instruction to a smaller
+    integer type (e.g. from i8 to i2), leaving us in the somewhat perverse
+    situation that jump-threading would work before running instcombine,
+    but not after. Since instcombine produces this pattern, I think we
+    need to consider it canonical and support it in JumpThreading.
+    In general, for limiting recursion, I think the existing restriction
+    to phi and cmp nodes should be sufficient to avoid looking through
+    unprofitable chains of instructions.

+    [SCEV] Don't expand Wrap predicate using inttoptr in ni addrspaces
+    
+    Summary:
+    In non-integral address spaces, we're not allowed to introduce inttoptr/ptrtoint
+    intrinsics. Instead, we need to expand any pointer arithmetic as geps on the
+    base pointer. Luckily this is a common task for SCEV, so all we have to do here
+    is hook up the corresponding helper function and add test case.
+    
+    Fixes PR38290

+    [VNCoercion] Disallow coercion between different ni addrspaces
+    
+    Summary:
+    I'm not sure if it would be legal by the IR reference to introduce
+    an addrspacecast here, since the IR reference is a bit vague on
+    the exact semantics, but at least for our usage of it (and I
+    suspect for many other's usage) it is not. For us, addrspacecasts
+    between non-integral address spaces carry frontend information that the
+    optimizer cannot deduce afterwards in a generic way (though we
+    have frontend specific passes in our pipline that do propagate
+    these). In any case, I'm sure nobody is using it this way at
+    the moment, since it would have introduced inttoptrs, which
+    are definitely illegal.

+
+    RFC: [SCEV] Add explicit representations of umin/smin
+    
+    Summary:
+    Currently we express umin as `~umax(~x, ~y)`. However, this becomes
+    a problem for operands in non-integral pointer spaces, because `~x`
+    is not something we can compute for `x` non-integral. However, since
+    comparisons are generally still allowed, we are actually able to
+    express `umin(x, y)` directly as long as we don't try to express is
+    as a umax. Support this by adding an explicit umin/smin representation
+    to SCEV. We do this by factoring the existing getUMax/getSMax functions
+    into a new function that does all four. The previous two functions
+    were largely identical, except that the SMax variant used `isKnownPredicate`
+    while the UMax variant used `isKnownViaNonRecursiveReasoning`.
+    
+    Trying to make the UMax variant also use `isKnownPredicate` yields to
+    an infinite recursion, while trying to make the `SMax` variant use
+    `isKnownViaNonRecursiveReasoning` causes
+    `Transforms/IndVarSimplify/backedge-on-min-max.ll` to fail.
+    
+    I would appreciate any insight into which predicate is correct here.

+    [LSR] Don't force bases of foldable formulae to the final type.
+    
+    Summary:
+    Before emitting code for scaled registers, we prevent
+    SCEVExpander from hoisting any scaled addressing mode
+    by emitting all the bases first. However, these bases
+    are being forced to the final type, resulting in some
+    odd code.
+    
+    For example, if the type of the base is an integer and
+    the final type is a pointer, we will emit an inttoptr
+    for the base, a ptrtoint for the scale, and then a
+    'reverse' GEP where the GEP pointer is actually the base
+    integer and the index is the pointer. It's more intuitive
+    to use the pointer as a pointer and the integer as index.

+    [X86] Fix some isel patterns that used aligned vector load instructions with unaligned predicates.
+    
+    These patterns weren't checking the alignment of the load, but were using the aligned instructions. This will cause a GP fault if the data isn't aligned.
+    
+    I believe these were introduced in r312450.

+    [SelectionDAG] Fix UpdateChains handling of TokenFactors
+    
+    Summary:
+    In Instruction Selection UpdateChains replaces all matched Nodes'
+    chain references including interior token factors and deletes them.
+    This may allow nodes which depend on these interior nodes but are not
+    part of the set of matched nodes to be left with a dangling dependence.
