[Vm-dev] GCC version > 4.4

[Norbert Hartl]

I tried to compile the vm with a newer gcc than 4.4. It didn't work with 4.9 and I tested 4.8 and 4.7 which do not work either. The last one I was successful was 4.4. Trying to compile it gives an error about conflicting types. Looking into brought to the signature of procedures in cogit.c. Here we have something like

static sqInt abstractRegisterForConcreteRegister(AbstractInstruction * self_in_abstractRegisterForConcreteRegister, sqInt reg) NoDbgRegParms;

and the definition is

static sqInt
abstractRegisterForConcreteRegister(AbstractInstruction * self_in_abstractRegisterForConcreteRegister, sqInt reg)
{

It seems that the NoDbgRegParms is changing the game. So I assume the signatures have to be exactly the same. Putting NoDbgRegParms after the parentheses in the definition does not work. So I changed both to have it in front like

NoDbgRegParms static sqInt abstractRegisterForConcreteRegister(AbstractInstruction * self_in_abstractRegisterForConcreteRegister, sqInt reg);

and

NoDbgRegParms static sqInt
abstractRegisterForConcreteRegister(AbstractInstruction * self_in_abstractRegisterForConcreteRegister, sqInt reg)
{

and this compiles for me. So two questions:

- am I write with my assumption and is the change a valid solution for the problem
- if yes will you change it or should I give it a try. It will take some time for me to figure out where that is exactly in the VMMaker code and I assume that it is a no-brainer for someone developing actively with VMMaker
