2002-02-25 Jochen Hoenicke <jochen@gnu.org>
* jode/bytecode/ClassInfo.java.in (read): Don't check for a
maximum version anymore. Sun changes it with every release without
changing the bytecode format.

2001-08-12 Jochen Hoenicke <jochen@gnu.org>
* net/sf/jode/bytecode/TypeSignature.java:
(getArgumentSize): Renamed to ...

(skipType): Made private.
* net/sf/jode/jvm/CodeVerifier.java:
(initInfo): Use TypeSignature.getParameterTypes instead of skipType.
* net/sf/jode/jvm/SyntheticAnalyzer.java:
(checkGetClass): Be more lenient with the types, they are already
checked by the CodeVerifier. This is to support jdk-1.4.
* net/sf/jode/expr/InvokeOperator.java
(dumpExpression): Fixed the check for null outerExpr.
* net/sf/jode/flow/FlowBlock.java:
(checkConsistent): Allow lastModified in a finally block.

handlers again. This time checked with javac 1.3, javac 1.1 and
jikes.
(checkTryCatchOrder): New method that was previously part of
analyze.
(analyze): Use checkTryCatchOrder. Don't merge try and catch flow
blocks anymore, leave it to the analyzeXXX methods.
(mergeTryCatch): New method.
(analyzeCatchBlock): Get catchFlow as parameter. Call
mergeTryCatch.
(transformSubroutine): Handle POP-only subroutines.
(removeJSR): Don't do special case for catchBlock any more. This
is because catchFlow isn't yet merged when this method is called.
(checkAndRemoveJSR): Likewise.
(checkAndRemoveMonitorExit): Likewise. Merge subroutine only if
we are the only predecessor.
(analyzeSynchronized): Get catchFlow as parameter. Call
mergeTryCatch.
(mergeFinallyBlocks): New method, calls mergeTryCatch and does the
common part of mergeFinally and mergeSpecialFinally.
(analyzeFinally): Simplified, after checking and removing JSR, it
does immediately analyze and transform subroutine to get the
finallyBlock. Then it throws away the catchFlow and calls
mergeFinallyBlocks.
(analyzeSpecialFinally): Simplified, after checking it only handles
the jumps in the try part and then call mergeFinallyBlocks.
2001-08-08 Jochen Hoenicke <jochen@gnu.org>

2001-07-15 Jochen Hoenicke <jochen@gnu.org>
Applied patches from 2001-05-26 of Jode 1.1 tree:
* configure.in: Set version to 1.1.
* jode/swingui/Main.java (main): Also use bootclasspath if no
classpath given.
* jode/decompiler/MethodAnalyzer.java (skipWriting): Don't skip
empty constructor that have a throws clause.
* configure.in: Determine whether jdk1.1 resp. jdk1.2. Call jcpp
in config.status.
* jode/expr/Expression.java (makeInitializer): Now takes the
type of the initialization. Changed all callers.
* jode/expr/ConstantArrayOperator.java (makeInitializer): Check
that type is our array type, otherwise we can't omit new Array[].
* jode/decompiler/LocalInfo.java (markFinal): Don't check that
only one write is present. If two writes are in an then and an
else branch of an if, the local can still be final.
* jode/type/ArrayType.java (getSubType): Handle array of integer
types correctly: byte[] is something completely different than
int[].
(getSuperType): Likewise.
* jode/expr/FieldOperator.java (getFieldInfo): New function.
(needsCast): A cast is also needed if the field is private or
package scope and the current type can't access the field.
* jode/expr/InvokeOperator.java (getMethodInfo): New function.
(needsCast): A cast is also needed if the method is private or
package scope and the current type can't access the method.
* jode/expr/ArrayStoreOperator.java (dumpExpression): Check if a
cast of the array expression is needed.
* jode/expr/TransformConstructors.java
(transformFieldInitializers): Don't allow moving method invocations
that throw a checked exception.
* jode/bytecode/MethodInfo.java (readAttribute): Read Exceptions
attribute even when not all attributes should be read. They are
needed by TransformConstructors, see above.
* jode/decompiler/TabbedPrintWriter.java (saveOps): Don't allow
line breaks in not completed expressions since implicit parentheses
would destroy the syntax. No need to put line break option on stack.
(restoreOps): Adapted Stack format.
* jode/decompiler/ClassAnalyzer.java (dumpDeclaration): Moved
Code from dumpSource here. Don't put a line break after closing
brace.
(dumpSource): call dumpDeclaration and add a line break.
(dumpBlock): Moved dropInfo(ATTRIBS) here.
* jode/decompiler/ClassAnalyzer.java (STRICTFP): New Constant.
(isStrictFP): New function.
(initialize): Set strictfp modifier if a constructor has it set.
(dumpSource): Handle strictfp modifier.
* jode/decompiler/MethodAnalyzer.java (STRICTFP): New Constant.
(isStrictFP): New function.
(dumpSource): Handle strictfp modifier.
* jode/jvm/SyntheticAnalyzer.java (checkAccess): Check for a
special putfield access, where the set value is returned. Allow
the modifier of field/method to be protected and the class to be
a superclass.
(checkStaticAccess): Likewise.
(ACCESSDUPPUTFIELD): New Constant.
(ACCESSDUPPUTSTATIC): New Constant.
* jode/expr/InvokeOperator.java (simplifyAccess): Handle new
synthetics.
* jode/flow/SpecialBlock.java (removePop): Remove pop also for
non void store instructions.
* jode/decompiler/MethodAnalyzer.java (skipWriting): Also skip
the new synthetics.
* jode/decompiler/Main.java (main): Call System.exit() after
everything was compiled.
* jode/flow/TransformExceptionHandlers.java (removeJSR):
Renamed back from removeBadJSR (see patch from 2001-02-04). The
checkAndRemove* functions mustn't change the successors while they
iterate over them. Instead of removing good jsr they mark them as
good and removeJSR will finally remove them.
(checkAndRemoveJSR): See above.
(checkAndRemoveMonitorExit): See above.
* jode/flow/JsrBlock.java (good): New variable, see above.
(setGood): New method.
(isGood): New method.
2001-07-15 Jochen Hoenicke <jochen@gnu.org>
Applied patch from 2001-05-08 of Jode 1.1 tree:
* jode/jvm/CodeVerifier.java (doVerify): Don't check for
uninitialized objects in local or stack slots on backwards jump or
exception blocks. Sun's jdk also doesn't check it, and I never
understood why it is necessary. But see JVM Spec 4.9.4.
2001-07-15 Jochen Hoenicke <jochen@gnu.org>
Applied patch from 2001-05-02 of Jode 1.1 tree:
* jode/obfuscator/modules/ConstantAnalyzer.java (handleOpcode):
Added divide by zero checks for opc_irem and opc_lrem.
2001-07-15 Jochen Hoenicke <jochen@gnu.org>
Applied patches from 2001-02-27 of Jode 1.1 tree:
* acinclude.m4 (JODE_CHECK_CLASS): Changed "test -e" to "-f" since
-e is not supported on all architectures (Solaris) and -f is more
correct anyway.
Reported by Erik Modén.
* jode/swingui/Main.java (AreaWriter): Convert all kinds of
line breaks (CR+LF, CR, LF) to a LF character, which a JTextArea
understands.
2001-07-15 Jochen Hoenicke <jochen@gnu.org>
Applied patch from 2001-02-04 of Jode 1.1 tree:
* jode/expr/IfThenElseOperator.java (simplify): Allow in the class$
simplification the then and else part to be swapped.
* jode/type/ClassType.java (keywords): Added the package
and import keywords.
* jode/flow/TransformExceptionHandlers.java:
(getPredecessor): New function.
(getMonitorExitSlot): New function.
(skipFinExitChain): New function.
(removeJSR): Replaced by ...
(removeBadJSR): ... this.
(checkAndRemoveJSR): Use the new functions. Much simpler and
handles nested synchronized blocks. It now traces the whole JSR
and monitorexit chain before a jump to the first entry via
skipFinExitChain, then checks and remove the first JSR
resp. monitorexit. JSR jumps are simply ignored now.
(checkAndRemoveMonitorExit): likewise.
* jode/flow/StructuredBlock.java (prependBlock): New function.
* jode/flow/CatchBlock.java (makeDeclaration): Generate name
of dummyLocal, since nobody else will generate it.
* jode/bytecode/BasicBlockReader.java (readCode): Remove bogus
exceptionHandlers, whose catchers just throw the exception again.
This kind of entries are inserted by an obfuscator and would break
JODE.
* jode/util/UnifyHash.java (iterateHashCode): Call cleanUp,
to clean unneeded references.
* jode/flow/TransformConstructors.java (transformOneField):
Changed to private. Take field number as parameter. Check that
expression doesn't contain a FieldOperator for a later field of
the same class or a PutFieldOperator. Changed all callers.
2001-07-15 Jochen Hoenicke <jochen@gnu.org>
Applied patch from 2001-02-01 of Jode 1.1 tree:
* jode/jvm/CodeVerifier.java (Type.mergeType): If array elem
types can't be merged, return tObject as common super type.
* jode/type/ArrayType.java (getGeneralizedType): If array elem
type can't be intersected, return tObject as common super type.
2001-07-15 Jochen Hoenicke <jochen@gnu.org>
Applied patch from Jode 1.1 tree:
* jode/expr/Expression.java (updateParentTypes): Call setType,
instead of merging the types. Other childs want to know about the
type change as well.
* jode/decompiler/LocalInfo.java (combineWith): Reorganized a bit,
but no changes.
* jode/expr/InvokeOperator.java (dumpExpression): Always print
the ThisOperator if a field is from a parent class of an outer
class is used. And always qualify the this operator if not
innermost.
2001-07-14 Jochen Hoenicke <jochen@gnu.org>
Applied patches from the Jode 1.1 tree:
* jode/decompiler/TabbedPrintWriter.java: Better gnu style handling:
(openBraceClass) (closeBraceClass)
(openBraceNoIndent) (closeBraceNoIndent): new functions.
(closeBraceNoSpace): Removed.
* jode/decompiler/TabbedPrintWriter.java (GNU_SPACING): new constant.
(printOptionalSpace): Print space for GNU_SPACING.
* jode/decompiler/Options.java (setOptions): changed gnu style
to include GNU_SPACING.
* jode/decompiler/ClassAnalyzer.java (dumpSource): Use
open/closeBraceClass.
* jode/decompiler/MethodAnalyzer.java (dumpSource): Use
open/closeBraceNoIndent. Call printOptionalSpace.
* jode/decompiler/InvokeOperator.java (dumpExpression):
Call printOptionalSpace, use open/closeBraceClass for inner
classes.
* jode/decompiler/UnaryOperator.java (dumpExpression): Call
printOptionalSpace.
Added pascal style from Rolf Howarth <rolf@squarebox.co.uk>
* jode/decompiler/Decompiler.java (setOption): detect pascal option.
* jode/decompiler/TabbedPrintWriter.java (BRACE_FLUSH_LEFT):
new constant.
(openBrace, openBraceContinue, closeBrace, closeBraceNoSpace,
closeBraceContinue): handle flush left.
* jode/type/NullType.java (intersection): Removed, since the
version in ReferenceType is more correct. Before
tNull.isOfType(tRange(X,tNull)) returned false, which lead to
incorrect behaviour in InvokeOperator.needsCast.
* jode/decompiler/FieldAnalyzer.java (dumpSource): Removed the
"= null" hack for final fields; it was not correct, since the
field could be initialized in a constructor.
* jode/decompiler/TabbedPrintWriter.java (BreakPoint.endOp):
Simplified the code, copy options always from child.
* jode/expr/InvokeOperator.java (isGetClass): Allow the method to
be declared inside an outer class: We simply check if we can get
the method analyzer.
(simplify): handle unifyParam.
* jode/expr/PopOperator.java (getBreakPenalty): return penalty of
inner expression. (dumpExpression): Call dumpExpression of
subexpression immediately without priority.
