[xmlvm-users] Synchronized Keyword

[Markus H. <ma...@ti...>]

Hi,

I have a problem with the synchronized keyword. The generated ObjC- 
code does not compile. First error is a simple spelling error: http://github.com/tisoft/xmlvm/commit/2d75e56167dd41eee2705dd110895308ac256a80

But fixing that doesn't help since the generated code is still wrong.

Just try to convert a simple class like:

public class X{
	public void test(){
		synchronized(this){
		}
	}
}

This creates some uncompilable stuff in ObjC:

- (void) test
{
     XMLVMElem _stack[2];
     XMLVMElem _locals[3];

     int _sp = 0;
     XMLVMElem _op1, _op2, _op3;
     NSAutoreleasePool* _pool = [[NSAutoreleasePool alloc] init];
     _locals[0].o = self;
     label1:;
     _stack[_sp++].o = _locals[0].o;
     _op1 = _stack[_sp - 1];
     _stack[_sp++] = _op1;
     _op1.o = _stack[--_sp].o;
     _locals[1].o = _op1.o;
     _op1.o = _stack[--_sp].o;
   	@synchronized(_op1.o) {
     @try {
     _stack[_sp++].o = _locals[1].o;
     }
     } @catch (java_lang_Exception* _ex) {
         _stack[_sp++].o = _ex;
         goto label3;
     }
     goto label0;
     @try {
     label3:;
     _op1.o = _stack[--_sp].o;
     _locals[2].o = _op1.o;
     _stack[_sp++].o = _locals[1].o;
     }
     } @catch (java_lang_Exception* _ex) {
         _stack[_sp++].o = _ex;
         goto label3;
     }
     _stack[_sp++].o = _locals[2].o;
     _op1.o = _stack[--_sp].o;
     @throw _op1.o;
     label0:;
     [_pool release];
     return;
}

I'm not able to fix it myself, since I don't understand the converting  
stuff yet, so it would be great if someone of you could look into this.

Greetings,
Markus
