Avoid Pop/Push instruction and fixed register assignments about mosa-project HOT 7 CLOSED

I don't see ways to create a virtual register operand without accessing a BaseMethodCompiler instance. Perhaps I should expose it to BaseCallingConvention?

from mosa-project.

Cant you use Operand.CreateVirtualRegister(MosaType type, int index)?

from mosa-project.

It requires an index argument, which is maintained by VirtualRegisters instance in the BaseMethodCompiler instance. I'm not sure if there is a consequence of providing invalid index.

Yeah that does seem to be a problem, why isn't the virtual register allocater statically accessible?
Would that be a possible solution?

from mosa-project.

Virtual register can be created by calling from any class that derives from BaseMethodCompilerStage.

Operand v1 = AllocateVirtualRegister(typeSystem.BuiltIn.U4);

or from any class that derives from BaseMethodCompiler:

VirtualRegisters.Allocate(typeSystem.BuiltIn.U4);

Do not call Operand.CreateVirtualRegister method directly.

Yes I'm aware of it. However, the place that need the virtual register is within BaseCallingConvention/BaseArchitecture which is neither derived from BaseMethodCompilerStage nor BaseMethodCompiler, so I was thinking about adding a parameter to obtain the compiler instance in the place. What do you think about it?

from mosa-project.

Yes, go ahead and pass the compiler instance as a parameter.
