-      form, that is based on (or derived from) the Work and for which the 
-      editorial revisions, annotations, elaborations, or other modifications

-      of this License, Derivative Works shall not include works that remain

-      by such Contributor that are necessarily infringed by their 
-      Contribution(s) alone or by combination of their Contribution(s) 
-      with the Work to which such Contribution(s) was submitted. If You 
-      institute patent litigation against any entity (including a 
-      cross-claim or counterclaim in a lawsuit) alleging that the Work 
-      or a Contribution incorporated within the Work constitutes direct 
-      or contributory patent infringement, then any patent licenses 
-      granted to You under this License for that Work shall terminate 
-      as of the date such litigation is filed. 
- 
-    4. Redistribution. You may reproduce and distribute copies of the 
-      Work or Derivative Works thereof in any medium, with or without 
-      modifications, and in Source or Object form, provided that You

- 
-      (c) You must retain, in the Source form of any Derivative Works 
-          that You distribute, all copyright, patent, trademark, and 
-          attribution notices from the Source form of the Work, 
-          excluding those notices that do not pertain to any part of 
-          the Derivative Works; and 
- 
-      (d) If the Work includes a "NOTICE" text file as part of its 
-          distribution, then any Derivative Works that You distribute must 
-          include a readable copy of the attribution notices contained 
-          within such NOTICE file, excluding those notices that do not 
-          pertain to any part of the Derivative Works, in at least one 
-          of the following places: within a NOTICE text file distributed 
-          as part of the Derivative Works; within the Source form or 
-          documentation, if provided along with the Derivative Works; or, 
-          within a display generated by the Derivative Works, if and 
-          wherever such third-party notices normally appear. The contents 
-          of the NOTICE file are for informational purposes only and 
-          do not modify the License. You may add Your own attribution 
-          notices within Derivative Works that You distribute, alongside 
-          or as an addendum to the NOTICE text from the Work, provided 
-          that such additional attribution notices cannot be construed 
-          as modifying the License. 
- 
-      You may add Your own copyright statement to Your modifications and 
-      may provide additional or different license terms and conditions 
-      for use, reproduction, or distribution of Your modifications, or 
-      for any such Derivative Works as a whole, provided Your use, 
-      reproduction, and distribution of the Work otherwise complies with 
-      the conditions stated in this License. 
- 
-    5. Submission of Contributions. Unless You explicitly state otherwise, 
-      any Contribution intentionally submitted for inclusion in the Work 
-      by You to the Licensor shall be under the terms and conditions of 
-      this License, without any additional terms or conditions. 
-      Notwithstanding the above, nothing herein shall supersede or modify 
-      the terms of any separate license agreement you may have executed 
-      with Licensor regarding such Contributions. 
- 
-    6. Trademarks. This License does not grant permission to use the trade 
-      names, trademarks, service marks, or product names of the Licensor, 
-      except as required for reasonable and customary use in describing the 
-      origin of the Work and reproducing the content of the NOTICE file. 
- 
-    7. Disclaimer of Warranty. Unless required by applicable law or 
-      agreed to in writing, Licensor provides the Work (and each 
-      Contributor provides its Contributions) on an "AS IS" BASIS, 
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or 
-      implied, including, without limitation, any warranties or conditions 
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A 
-      PARTICULAR PURPOSE. You are solely responsible for determining the 
-      appropriateness of using or redistributing the Work and assume any 
-      risks associated with Your exercise of permissions under this License. 
- 
-    8. Limitation of Liability. In no event and under no legal theory, 
-      whether in tort (including negligence), contract, or otherwise, 
-      unless required by applicable law (such as deliberate and grossly 
-      negligent acts) or agreed to in writing, shall any Contributor be 
-      liable to You for damages, including any direct, indirect, special, 
-      incidental, or consequential damages of any character arising as a 
-      result of this License or out of the use or inability to use the 
-      Work (including but not limited to damages for loss of goodwill, 
-      work stoppage, computer failure or malfunction, or any and all 
-      other commercial damages or losses), even if such Contributor 
-      has been advised of the possibility of such damages. 
- 
-    9. Accepting Warranty or Additional Liability. While redistributing 
-      the Work or Derivative Works thereof, You may choose to offer, 
-      and charge a fee for, acceptance of support, warranty, indemnity, 
-      or other liability obligations and/or rights consistent with this 
-      License. However, in accepting such obligations, You may act only 
-      on Your own behalf and on Your sole responsibility, not on behalf 
-      of any other Contributor, and only if You agree to indemnify, 
-      defend, and hold each Contributor harmless for any liability 
-      incurred by, or claims asserted against, such Contributor by reason 
-      of your accepting any such warranty or additional liability.

-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 improvements: 
- 
-1. Do proper LiveStacks analysis 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.

+
+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 improvements:
+
+1. Do proper LiveStacks analysis 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.
