-说明:
-======
-
-本项目是从ObjectWeb ASM v3.1(http://asm.objectweb.org/license.html)中移植,并做了如下修改:
-
-* 修改package
- org.objectweb.asm -> com.alibaba.citrus.asm
- org/objectweb/asm -> com/alibaba/citrus/asm
-
-* 修改单元测试:
- 1. 只保留了conform测试。
- 2. 增加AsmTestParams辅助类。
- 3. 修改AbstractTest类,使之:
- # 使用AsmTestParams而不是System properties。
- # 改进suite的名称,加上“-part”
- # 将stream改成URL,避免内存溢出
- # 添加exclude参数,排除多余的文件
- # 关闭zip流
- # 设置一个suite中test的最大数量
- 4. 修改了ASMifierUnitTest、CheckClassAdapterUnitTest、TraceClassAdapterUnitTest中传给main函数的参数。
- 5. 修改了ASMifierTest、GASMifierTest中的参数:clazz=java.lang
- 6. 修改了ClassWriterComputeFramesTest、LocalVariablesSorterTest2、SimpleVerifierTest中的参数:parts=2
- 7. 修改所有对AbstractTest.is的引用,改成openStream()调用。
- 8. 修改了SerialVersionUIDAdderUnitTest中的UID,以便通过测试。
- 9. ClassNodeTest中,设置InsnList.check = false,以便通过测试。
-
-* 将StringBuffer改成StringBuilder
-
-* Cleanup
-
-* 测试要点:内存需求非常大,最好分配1G-2G的空间:-Xms1536M -Xmx1536M -XX:MaxPermSize=512M

-final class Frame {
-
- /*
- * Frames are computed in a two steps process: during the visit of each instruction, the state of the frame at the
- * end of current basic block is updated by simulating the action of the instruction on the previous state of this
- * so called "output frame". In visitMaxs, a fix point algorithm is used to compute the "input frame" of each basic
- * block, i.e. the stack map frame at the begining of the basic block, starting from the input frame of the first
- * basic block (which is computed from the method descriptor), and by using the previously computed output frames to
- * compute the input state of the other blocks. All output and input frames are stored as arrays of integers.
- * Reference and array types are represented by an index into a type table (which is not the same as the constant
- * pool of the class, in order to avoid adding unnecessary constants in the pool - not all computed frames will end
- * up being stored in the stack map table). This allows very fast type comparisons. Output stack map frames are
- * computed relatively to the input frame of the basic block, which is not yet known when output frames are
- * computed. It is therefore necessary to be able to represent abstract types such as "the type at position x in the
- * input frame locals" or "the type at position x from the top of the input frame stack" or even "the type at
- * position x in the input frame, with y more (or less) array dimensions". This explains the rather complicated type
- * format used in output frames. This format is the following: DIM KIND VALUE (4, 4 and 24 bits). DIM is a signed
- * number of array dimensions (from -8 to 7). KIND is either BASE, LOCAL or STACK. BASE is used for types that are
- * not relative to the input frame. LOCAL is used for types that are relative to the input local variable types.
- * STACK is used for types that are relative to the input stack types. VALUE depends on KIND. For LOCAL types, it is
- * an index in the input local variable types. For STACK types, it is a position relatively to the top of input
- * frame stack. For BASE types, it is either one of the constants defined in FrameVisitor, or for OBJECT and
- * UNINITIALIZED types, a tag and an index in the type table. Output frames can contain types of any kind and with a
- * positive or negative dimension (and even unassigned types, represented by 0 - which does not correspond to any
- * valid type value). Input frames can only contain BASE types of positive or null dimension. In all cases the type
- * table contains only internal type names (array type descriptors are forbidden - dimensions must be represented
- * through the DIM field). The LONG and DOUBLE types are always represented by using two slots (LONG + TOP or DOUBLE +

-/**
- * A {@link ClassAdapter} that adds a serial version unique identifier to a
- * class if missing. Here is typical usage of this class:
- *
- *
- * ClassWriter cw = new ClassWriter(...);
- * ClassVisitor sv = new SerialVersionUIDAdder(cw);
- * ClassVisitor ca = new MyClassAdapter(sv);
- * new ClassReader(orginalClass).accept(ca, false);
- *
- * The serialVersionUID is computed using the signature of a stream of bytes
- * that reflect the class definition. The National Institute of Standards and
- * Technology (NIST) Secure Hash Algorithm (SHA-1) is used to compute a
- * signature for the stream. The first two 32-bit quantities are used to form a
- * 64-bit hash. A java.lang.DataOutputStream is used to convert primitive data
- * types to a sequence of bytes. The values input to the stream are defined by
- * the Java Virtual Machine (VM) specification for classes.
- * The sequence of items in the stream is as follows:
- * 1. The class name written using UTF encoding.
- * 2. The class modifiers written as a 32-bit integer.
- * 3. The name of each interface sorted by name written using UTF encoding.
- * 4. For each field of the class sorted by field name (except private static
- * and private transient fields):
- * 1. The name of the field in UTF encoding.
- * 2. The modifiers of the field written as a 32-bit integer.
- * 3. The descriptor of the field in UTF encoding
- * 5. If a class initializer exists, write out the following:
- * 1. The name of the method, <clinit>, in UTF encoding.
- * 2. The modifier of the method, java.lang.reflect.Modifier.STATIC,
- * written as a 32-bit integer.
- * 3. The descriptor of the method, ()V, in UTF encoding.
- * 6. For each non-private constructor sorted by method name and signature:
- * 1. The name of the method, <init>, in UTF encoding.
- * 2. The modifiers of the method written as a 32-bit integer.
- * 3. The descriptor of the method in UTF encoding.
- * 7. For each non-private method sorted by method name and signature:
- * 1. The name of the method in UTF encoding.
- * 2. The modifiers of the method written as a 32-bit integer.
- * 3. The descriptor of the method in UTF encoding.
- * 8. The SHA-1 algorithm is executed on the stream of bytes produced by
- * DataOutputStream and produces five 32-bit values sha[0..4].
- * 9. The hash value is assembled from the first and second 32-bit values of
- * the SHA-1 message digest. If the result of the message digest, the five
- * 32-bit words H0 H1 H2 H3 H4, is in an array of five int values named
- * sha, the hash value would be computed as follows:
- * long hash = ((sha[0] >>> 24) & 0xFF) |
- * ((sha[0] >>> 16) & 0xFF) << 8 |
- * ((sha[0] >>> 8) & 0xFF) << 16 |
- * ((sha[0] >>> 0) & 0xFF) << 24 |
- * ((sha[1] >>> 24) & 0xFF) << 32 |
- * ((sha[1] >>> 16) & 0xFF) << 40 |
- * ((sha[1] >>> 8) & 0xFF) << 48 |
- * ((sha[1] >>> 0) & 0xFF) << 56;

-/**
- * A {@link ClassAdapter} that checks that its methods are properly used. More
- * precisely this class adapter checks each method call individually, based
- * only on its arguments, but does not check the sequence
- * of method calls. For example, the invalid sequence
- * visitField(ACC_PUBLIC, "i", "I", null)visitField(ACC_PUBLIC,
- * "i", "D", null) will not be detected by this class adapter.
- *
- * CheckClassAdapter can be also used to verify bytecode
- * transformations in order to make sure transformed bytecode is sane. For
- * example:
- *
- *
- * InputStream is = ...; // get bytes for the source class
- * ClassReader cr = new ClassReader(is);
- * ClassWriter cw = new ClassWriter(cr, ClassWriter.COMPUTE_MAXS);
- * ClassVisitor cv = new <b>MyClassAdapter</b>(new CheckClassAdapter(cw));
- * cr.accept(cv, 0);
- *
- * StringWriter sw = new StringWriter();
- * PrintWriter pw = new PrintWriter(sw);
- * CheckClassAdapter.verify(new ClassReader(cw.toByteArray()), false, pw);
- * assertTrue(sw.toString(), sw.toString().length()==0);
- *
- *
- * Above code runs transformed bytecode trough the
- * CheckClassAdapter. It won't be exactly the same verification as
- * JVM does, but it run data flow analysis for the code of each method and
- * checks that expectations are met for each method instruction.
- *
- * If method bytecode has errors, assertion text will show the erroneous
- * instruction number and dump of the failed method with information about
- * locals and stack slot for each instruction. For example (format is -
- * insnNumber locals : stack):
- *
- *
- *
- * In the above output you can see that variable 1 loaded by
- * ILOAD 1 instruction at position 00071 is not
- * initialized. You can also see that at the beginning of the method (code
- * inserted by the transformation) variable 2 is initialized.
- *
- * Note that when used like that, CheckClassAdapter.verify() can
- * trigger additional class loading, because it is using
- * SimpleVerifier.
