Small progress.
The stack interpreter and cog VMs share the LargeIntegers plugin, but stack: (16r8000000000000000 * 16) printStringHex."--> '80000000000000000' " cog: (16r8000000000000000 * 16) printStringHex." --> '0' "
I was able to build a SpurVMMaker.image using the stack-interpreter VM and would like to invoke: StackToRegisterMappingCogit genAndDis: Integer class>>#xReadFrom:base:
But have had zero success in building the required GdbARMv8Plugin [Linux/aarch64].
Can some kind soul who actually knows how to deal with the fragile and complex C environment help me out?
Thanks much, -KenD
