I use VMMaker class>>activeVMMakerClassFor: to create the VMMaker, and hence the code generator, using 'Cross' as the platform name, which yields a CrossPlatformVMMaker. Look at the methods in VMMaker class's configurations protocol. IMO, this is the right way to generate sources. e.g.

generateSqueakCogVM

^VMMaker

generate: CoInterpreter

and: StackToRegisterMappingCogit

with: #( MULTIPLEBYTECODESETS false

NewspeakVM false)

to: (FileDirectory default pathFromURI: 'oscogvm/src')

platformDir: (FileDirectory default pathFromURI: 'oscogvm/platforms')

including:#( ADPCMCodecPlugin AsynchFilePlugin BalloonEnginePlugin B3DAcceleratorPlugin

BMPReadWriterPlugin BitBltSimulation BochsIA32Plugin GdbARMPlugin CroquetPlugin DSAPlugin

Hi all!!

I was looking at the VMMaker sources and noticed that by default when generating my vm, the interpreter and cogit files are generated with different CodeGenerators:

CrossPlatformVMMaker>>createCodeGenerator
"Set up a CCodeGenerator for this VMMaker - A cross platform tree leaves it up to the makefiles to decide whether to use the global struct or not."

^CCodeGeneratorGlobalStructure new initialize;
globalStructDefined: true;
structDefDefine: 'USE_GLOBAL_STRUCT';
logger: logger;
yourself

VMMaker>>createCogitCodeGenerator
^CCodeGenerator new initialize
logger: logger;

yourself

Why should they use different code generators? Shouldn't they by default use the same?
