Add utility for dumping information from AIN files.
For now this is pretty simplistic. The main use is to dump HLL function
prototypes to help with writing stubs.
Future features:
* dump to JSON format
* full AIN dump which could be rebuilt by a complementary tool, e.g.
to enable editing bytecode for testing purposes.
...and add OutputLog.dll stubs.
The calling convention no longer has HLL functions reaching into the
stack. The previous implementation didn't even work since the return
value could overwrite an argument that needed to be freed.
HLL libraries are compiled into the executable rather than dynamically
loaded as in early versions of System 4. These days AliceSoft does the
same thing.
All array instructions supported by the SDK compiler, anyway. There are
a few instructions that were added in later versions, like A_FIND and
A_REVERSE.
Implement CALLMETHOD, SH_STRUCTREF and PUSHSTRUCTPAGE instructions.
Constructors are a bit tricky since SH_LOCALCREATE has to implicitly
call an arbitrary number of functions before it returns (just changing
the instruction pointer only allows for calling a single function).
To get around this, there is now a vm_call() function which is used to
call a function synchronously, before returning from the current
instruction.
Methods are implemented as functions, except that they get a struct page
as local variable -1.
Destructors are still not implemented.
An assortment of instructions have been implemented so far, mostly basic
stuff such as stack management. The following program can be executed:
int main(void)
{
hello(2);
for (;;) {
system.Peek();
system.Sleep(1);
}
return 0;
}
void hello(int n)
{
int i;
for (i = 0; i < n; i++) {
system.Output("Hello, world! " + string(i));
}
}
