Hi,
In kaffe VM http://www.lamedoc.com/kaffe/classMethod_8h_source.html i
find this code :
typedef struct _jmethodID {
Utf8Const* name;
parsed_signature_t* parsed_sig;
accessFlags accflags;
long idx; /* Index into class->vtable */
u2 stacksz;
u2 localsz;
....}
and in dalvik vm i find this one :
struct Method {
/* the class we are a part of */
ClassObject* clazz;
/* access flags; low 16 bits are defined by spec (could be u2?) */
u4 accessFlags;
/*
* For concrete virtual methods, this is the offset of the method
* in "vtable".
*
* For abstract methods in an interface class, this is the offset
* of the method in "iftable[n]->methodIndexArray".
*/
u2 methodIndex;
/*
* Method bounds; not needed for an abstract method.
*
* For a native method, we compute the size of the argument list,
and
* set "insSize" and "registerSize" equal to it.
*/
u2 registersSize; /* ins + locals */
u2 outsSize;
u2 insSize;
/* method name, e.g. "<init>" or "eatLunch" */
const char* name;
/*
* Method prototype descriptor string (return and argument types).
*
* TODO: This currently must specify the DexFile as well as the
proto_ids
* index, because generated Proxy classes don't have a DexFile.
We can
* remove the DexFile* and reduce the size of this struct if we
generate
* a DEX for proxies.
*/
DexProto prototype;
/* short-form method descriptor string */
const char* shorty;
/*
* The remaining items are not used for abstract or native
methods.
* (JNI is currently hijacking "insns" as a function pointer, set
* after the first call. For internal-native this stays null.)
*/
/* the actual code */
const u2* insns; /* instructions, in memory-
mapped .dex */
/* cached JNI argument and return-type hints */
int jniArgInfo;
/*
* Native method ptr; could be actual function or a JNI bridge.
We
* don't currently discriminate between DalvikBridgeFunc and
* DalvikNativeFunc; the former takes an argument superset (i.e.
two
* extra args) which will be ignored. If necessary we can use
* insns==NULL to detect JNI bridge vs. internal native.
*/
DalvikBridgeFunc nativeFunc;
/*
* Register map data, if available. This will point into the DEX
file
* if the data was computed during pre-verification, or into the
* linear alloc area if not.
*/
const RegisterMap* registerMap;
/* set if method was called during method profiling */
bool inProfile;};
And I want to know what's the equivalent of "stacksz" in dalvik vm?
thank you.
