-Common register allocation / spilling problem:
-
-        mul lr, r4, lr
-        str lr, [sp, #+52]
-        ldr lr, [r1, #+32]
-        sxth r3, r3
-        ldr r4, [sp, #+52]
-        mla r4, r3, lr, r4
-
-can be:
-
-        mul lr, r4, lr
-        mov r4, lr
-        str lr, [sp, #+52]
-        ldr lr, [r1, #+32]
-        sxth r3, r3
-        mla r4, r3, lr, r4
-
-and then "merge" mul and mov:
-
-        mul r4, r4, lr
-        str lr, [sp, #+52]
-        ldr lr, [r1, #+32]
-        sxth r3, r3
-        mla r4, r3, lr, r4
-
-It also increase the likelyhood the store may become dead.

-bb76 (0x8b03bf0, LLVM BB @0x8b032d0, ID#5):
-    Predecessors according to CFG: 0x8b0c5f0 (#3) 0x8b0a7c0 (#4)
-        %reg1039 = PHI %reg1070, mbb<bb76.outer,0x8b0c5f0>, %reg1037, mbb<bb27,0x8b0a7c0>
-
-Note ADDri is not a two-address instruction. However, its result %reg1037 is an
-operand of the PHI node in bb76 and its operand %reg1039 is the result of the
-PHI node. We should treat it as a two-address code and make sure the ADDri is
-scheduled after any node that reads %reg1039.

-//===---------------------------------------------------------------------===//
-
-Use local info (i.e. register scavenger) to assign it a free register to allow
-reuse:
-        ldr r3, [sp, #+4]
-        add r3, r3, #3
-        ldr r2, [sp, #+8]
-        add r2, r2, #2
-        ldr r1, [sp, #+4]  <==
-        add r1, r1, #1
-        ldr r0, [sp, #+4]
-        add r0, r0, #2

-LLVM aggressively lift CSE out of loop. Sometimes this can be negative side-
-effects:
-
-R1 = X + 4
-R2 = X + 7
-R3 = X + 15
-
-loop:
-load [i + R1]
-...
-load [i + R2]
-...
-load [i + R3]
-
-Suppose there is high register pressure, R1, R2, R3, can be spilled. We need
-to implement proper re-materialization to handle this:
-
-R1 = X + 4
-R2 = X + 7
-R3 = X + 15
-
-loop:
-R1 = X + 4  @ re-materialized
-load [i + R1]
-...
-R2 = X + 7 @ re-materialized
-load [i + R2]
-...
-R3 = X + 15 @ re-materialized
-load [i + R3]
-
-Furthermore, with re-association, we can enable sharing:
-
-R1 = X + 4
-R2 = X + 7
-R3 = X + 15
-
-loop:
-T = i + X
-load [T + 4]
-...
-load [T + 7]
-...
-load [T + 15]
-//===---------------------------------------------------------------------===//
-
-It's not always a good idea to choose rematerialization over spilling. If all
-the load / store instructions would be folded then spilling is cheaper because
-it won't require new live intervals / registers. See 2003-05-31-LongShifts for
-an example.
-
-//===---------------------------------------------------------------------===//
-
-With a copying garbage collector, derived pointers must not be retained across
-collector safe points; the collector could move the objects and invalidate the
-derived pointer. This is bad enough in the first place, but safe points can
-crop up unpredictably. Consider:
-
-        %array = load { i32, [0 x %obj] }** %array_addr
-        %nth_el = getelementptr { i32, [0 x %obj] }* %array, i32 0, i32 %n
-        %old = load %obj** %nth_el
-        %z = div i64 %x, %y
-        store %obj* %new, %obj** %nth_el
-
-If the i64 division is lowered to a libcall, then a safe point will (must)
-appear for the call site. If a collection occurs, %array and %nth_el no longer
-point into the correct object.
-
-The fix for this is to copy address calculations so that dependent pointers
-are never live across safe point boundaries. But the loads cannot be copied
-like this if there was an intervening store, so may be hard to get right.
-
-Only a concurrent mutator can trigger a collection at the libcall safe point.
-So single-threaded programs do not have this requirement, even with a copying
-collector. Still, LLVM optimizations would probably undo a front-end's careful
-work.
-
-//===---------------------------------------------------------------------===//
-
-The ocaml frametable structure supports liveness information. It would be good
-to support it.
-
-//===---------------------------------------------------------------------===//
-
-The FIXME in ComputeCommonTailLength in BranchFolding.cpp needs to be
-revisited. The check is there to work around a misuse of directives in inline
-assembly.
-
-//===---------------------------------------------------------------------===//
-
-It would be good to detect collector/target compatibility instead of silently
-doing the wrong thing.
-
-//===---------------------------------------------------------------------===//
-
-It would be really nice to be able to write patterns in .td files for copies,
-which would eliminate a bunch of explicit predicates on them (e.g. no side 
-effects).  Once this is in place, it would be even better to have tblgen 
-synthesize the various copy insertion/inspection methods in TargetInstrInfo.
-
-//===---------------------------------------------------------------------===//
-
-Stack coloring improvments:
-
-1. Do proper LiveStackAnalysis on all stack objects including those which are
-   not spill slots.
-2. Reorder objects to fill in gaps between objects.
-   e.g. 4, 1, <gap>, 4, 1, 1, 1, <gap>, 4 => 4, 1, 1, 1, 1, 4, 4
-
-//===---------------------------------------------------------------------===//
-
-The scheduler should be able to sort nearby instructions by their address. For
-example, in an expanded memset sequence it's not uncommon to see code like this:
-
-  movl $0, 4(%rdi)
-  movl $0, 8(%rdi)
-  movl $0, 12(%rdi)
-  movl $0, 0(%rdi)
-
-Each of the stores is independent, and the scheduler is currently making an
-arbitrary decision about the order.
-
-//===---------------------------------------------------------------------===//
-
-Another opportunitiy in this code is that the $0 could be moved to a register:
-
-  movl $0, 4(%rdi)
-  movl $0, 8(%rdi)
-  movl $0, 12(%rdi)
-  movl $0, 0(%rdi)
-
-This would save substantial code size, especially for longer sequences like
-this. It would be easy to have a rule telling isel to avoid matching MOV32mi
-if the immediate has more than some fixed number of uses. It's more involved
-to teach the register allocator how to do late folding to recover from
-excessive register pressure.
