The format of the new-array and its puts must be of the form: + * + * 

+ *   v0 <- new-array T vSize
+ *   ...
+ *   array-put v0 vValue1 vIndex1
+ *   ...
+ *   array-put v0 vValueN vIndexN
+ *
+ * + *

The flow between the array v0 and its puts must be linear with no other uses of v0 besides the + * array-put instructions, thus any no intermediate instruction (... above) must use v0 and also + * cannot have catch handlers that would transfer out control (those could then have uses of v0). + * + *

The allocation of the new-array can itself have catch handlers, in which case, those are to + * remain active on the translated code. Translated code can have two forms. + * + *

The first is using the original array allocation and filling in its data if it can be encoded: + * + * 

+ *   v0 <- new-array T vSize
+ *   filled-array-data v0
+ *   ...
+ *   ...
+ *
+ * + * The data payload is encoded directly in the instruction so no dependencies are needed for filling + * the data array. Thus, the fill is inserted at the point of the allocation. If the allocation has + * catch handlers its block must be split and the handlers put on the fill instruction too. This is + * correct only because there are no exceptional transfers in (...) that could observe the early + * initialization of the data. + * + *

The second is using filled-new-array and has the form: + * + * 

+ * ...
+ * ...
+ * v0 <- filled-new-array T vValue1 ... vValueN
+ *
+ * + * Here the correctness relies on no exceptional transfers in (...) that could observe the missing + * allocation of the array. The late allocation ensures that the values are available at allocation + * time. If the original allocation has catch handlers then the new allocation needs to link those + * too. In general that may require splitting the block twice so that the new allocation is the + * single throwing instruction in its block. + */ +public class ArrayConstructionSimplifier extends CodeRewriterPass { + + private final DexItemFactory dexItemFactory; + + public ArrayConstructionSimplifier(AppView appView) { + super(appView); + this.dexItemFactory = appView.dexItemFactory(); + } + + @Override + String getTimingId() { + return "ArrayConstructionSimplifier"; + } + + @Override + void rewriteCode(ProgramMethod method, IRCode code) { + WorkList worklist = WorkList.newIdentityWorkList(code.blocks); + while (worklist.hasNext()) { + BasicBlock block = worklist.next(); + simplifyArrayConstructionBlock(block, worklist, code, appView.options()); + } + } + + @Override + boolean shouldRewriteCode(ProgramMethod method, IRCode code) { + return appView.options().isGeneratingDex(); + } + + private void simplifyArrayConstructionBlock( + BasicBlock block, WorkList worklist, IRCode code, InternalOptions options) { + RewriteArrayOptions rewriteOptions = options.rewriteArrayOptions(); + InstructionListIterator it = block.listIterator(code); + while (it.hasNext()) { + FilledArrayCandidate candidate = computeFilledArrayCandidate(it.next(), rewriteOptions); + if (candidate == null) { + continue; + } + FilledArrayConversionInfo info = + computeConversionInfo( + candidate, new LinearFlowInstructionListIterator(code, block, it.nextIndex())); + if (info == null) { + continue; + } + + Instruction instructionAfterCandidate = it.peekNext(); + NewArrayEmpty newArrayEmpty = candidate.newArrayEmpty; + DexType arrayType = newArrayEmpty.type; + int size = candidate.size; + Set instructionsToRemove = SetUtils.newIdentityHashSet(size + 1); + if (candidate.useFilledNewArray()) { + assert newArrayEmpty.getLocalInfo() == null; + Instruction lastArrayPut = info.lastArrayPutIterator.peekPrevious(); + Value invokeValue = code.createValue(newArrayEmpty.getOutType(), null); + InvokeNewArray invoke = + new InvokeNewArray(arrayType, invokeValue, Arrays.asList(info.values)); + invoke.setPosition(lastArrayPut.getPosition()); + for (Value value : newArrayEmpty.inValues()) { + value.removeUser(newArrayEmpty); + } + newArrayEmpty.outValue().replaceUsers(invokeValue); + instructionsToRemove.add(newArrayEmpty); + + boolean originalAllocationPointHasHandlers = block.hasCatchHandlers(); + boolean insertionPointHasHandlers = lastArrayPut.getBlock().hasCatchHandlers(); + + if (!insertionPointHasHandlers && !originalAllocationPointHasHandlers) { + info.lastArrayPutIterator.add(invoke); + } else { + BasicBlock insertionBlock = info.lastArrayPutIterator.split(code); + if (originalAllocationPointHasHandlers) { + if (!insertionBlock.isTrivialGoto()) { + BasicBlock blockAfterInsertion = insertionBlock.listIterator(code).split(code); + assert insertionBlock.isTrivialGoto(); + worklist.addIfNotSeen(blockAfterInsertion); + } + insertionBlock.moveCatchHandlers(block); + } else { + worklist.addIfNotSeen(insertionBlock); + } + insertionBlock.listIterator(code).add(invoke); + } + } else { + assert candidate.useFilledArrayData(); + int elementSize = arrayType.elementSizeForPrimitiveArrayType(); + short[] contents = computeArrayFilledData(info.values, size, elementSize); + if (contents == null) { + continue; + } + // fill-array-data requires the new-array-empty instruction to remain, as it does not + // itself create an array. + NewArrayFilledData fillArray = + new NewArrayFilledData(newArrayEmpty.outValue(), elementSize, size, contents); + fillArray.setPosition(newArrayEmpty.getPosition()); + BasicBlock newBlock = + it.addThrowingInstructionToPossiblyThrowingBlock(code, null, fillArray, options); + if (newBlock != null) { + worklist.addIfNotSeen(newBlock); + } + } + + instructionsToRemove.addAll(info.arrayPutsToRemove); + Set visitedBlocks = Sets.newIdentityHashSet(); + for (Instruction instruction : instructionsToRemove) { + BasicBlock ownerBlock = instruction.getBlock(); + // If owner block is null, then the instruction has been removed already.

The format of the new-array and its puts must be of the form: - * - *

-   *   ...
-   *   array-put v0 vValue1 vIndex1
-   *   ...
-   *   array-put v0 vValueN vIndexN
-   *
- * - *

The flow between the array v0 and its puts must be linear with no other uses of v0 besides - * the array-put instructions, thus any no intermediate instruction (... above) must use v0 and - * also cannot have catch handlers that would transfer out control (those could then have uses of - * v0). - * - *

The allocation of the new-array can itself have catch handlers, in which case, those are to - * remain active on the translated code. Translated code can have two forms. - * - *

The first is using the original array allocation and filling in its data if it can be - * encoded: - * - * 

-   *   v0 <- new-array T vSize
-   *   filled-array-data v0
-   *   ...
-   *   ...
-   *
- * - * The data payload is encoded directly in the instruction so no dependencies are needed for - * filling the data array. Thus, the fill is inserted at the point of the allocation. If the - * allocation has catch handlers its block must be split and the handlers put on the fill - * instruction too. This is correct only because there are no exceptional transfers in (...) that - * could observe the early initialization of the data. - * - *

The second is using filled-new-array and has the form: - * - * 

-   * ...
-   * ...
-   * v0 <- filled-new-array T vValue1 ... vValueN
-   *
- * - * Here the correctness relies on no exceptional transfers in (...) that could observe the missing - * allocation of the array. The late allocation ensures that the values are available at - * allocation time. If the original allocation has catch handlers then the new allocation needs to - * link those too. In general that may require splitting the block twice so that the new - * allocation is the single throwing instruction in its block. - */ - public void simplifyArrayConstruction(IRCode code) { - if (options.isGeneratingClassFiles()) { - return; - } - WorkList worklist = WorkList.newIdentityWorkList(code.blocks); - while (worklist.hasNext()) { - BasicBlock block = worklist.next(); - simplifyArrayConstructionBlock(block, worklist, code, options); - } - } - - private void simplifyArrayConstructionBlock( - BasicBlock block, WorkList worklist, IRCode code, InternalOptions options) { - RewriteArrayOptions rewriteOptions = options.rewriteArrayOptions(); - InstructionListIterator it = block.listIterator(code); - while (it.hasNext()) { - FilledArrayCandidate candidate = computeFilledArrayCandidate(it.next(), rewriteOptions); - if (candidate == null) { - continue; - } - FilledArrayConversionInfo info = - computeConversionInfo( - candidate, new LinearFlowInstructionListIterator(code, block, it.nextIndex())); - if (info == null) { - continue; - } - - Instruction instructionAfterCandidate = it.peekNext(); - NewArrayEmpty newArrayEmpty = candidate.newArrayEmpty; - DexType arrayType = newArrayEmpty.type; - int size = candidate.size; - Set instructionsToRemove = SetUtils.newIdentityHashSet(size + 1); - if (candidate.useFilledNewArray()) { - assert newArrayEmpty.getLocalInfo() == null; - Instruction lastArrayPut = info.lastArrayPutIterator.peekPrevious(); - Value invokeValue = code.createValue(newArrayEmpty.getOutType(), null); - InvokeNewArray invoke = - new InvokeNewArray(arrayType, invokeValue, Arrays.asList(info.values)); - invoke.setPosition(lastArrayPut.getPosition()); - for (Value value : newArrayEmpty.inValues()) { - value.removeUser(newArrayEmpty); - } - newArrayEmpty.outValue().replaceUsers(invokeValue); - instructionsToRemove.add(newArrayEmpty); - - boolean originalAllocationPointHasHandlers = block.hasCatchHandlers(); - boolean insertionPointHasHandlers = lastArrayPut.getBlock().hasCatchHandlers(); - - if (!insertionPointHasHandlers && !originalAllocationPointHasHandlers) { - info.lastArrayPutIterator.add(invoke); - } else { - BasicBlock insertionBlock = info.lastArrayPutIterator.split(code); - if (originalAllocationPointHasHandlers) { - if (!insertionBlock.isTrivialGoto()) { - BasicBlock blockAfterInsertion = insertionBlock.listIterator(code).split(code); - assert insertionBlock.isTrivialGoto(); - worklist.addIfNotSeen(blockAfterInsertion); - } - insertionBlock.moveCatchHandlers(block); - } else { - worklist.addIfNotSeen(insertionBlock); - } - insertionBlock.listIterator(code).add(invoke); - } - } else { - assert candidate.useFilledArrayData(); - int elementSize = arrayType.elementSizeForPrimitiveArrayType(); - short[] contents = computeArrayFilledData(info.values, size, elementSize); - if (contents == null) { - continue; - } - // fill-array-data requires the new-array-empty instruction to remain, as it does not - // itself create an array. - NewArrayFilledData fillArray = - new NewArrayFilledData(newArrayEmpty.outValue(), elementSize, size, contents); - fillArray.setPosition(newArrayEmpty.getPosition()); - BasicBlock newBlock = - it.addThrowingInstructionToPossiblyThrowingBlock(code, null, fillArray, options); - if (newBlock != null) { - worklist.addIfNotSeen(newBlock); - } - } - - instructionsToRemove.addAll(info.arrayPutsToRemove); - Set visitedBlocks = Sets.newIdentityHashSet(); - for (Instruction instruction : instructionsToRemove) { - BasicBlock ownerBlock = instruction.getBlock(); - // If owner block is null, then the instruction has been removed already.

These are used to implement getOriginalMethodSignature() and getRenamedMethodSignature(), so that each lens does not need to add an implementation that recurses into the previous lens. This CL finishes this cleanup by introducing the methods getPreviousClassType(), getNextClassType(), getPreviousFieldSignature() and getNextFieldSignature(), and using these to implement getOriginalClassType(), lookupType(), getOriginalFieldSignature() and getRenamedFieldSignature().
