Fired up a vmmaker image as built by your script, updated to oscog-eem1071.
Ran VMMaker generateConfiguration
- attempted Squeak Stack VM (for Pi)
- attempted Squeak Spur Stack VM
- seemed to generate ok.
So maybe it produces a working spur vm but it doesn’t seem to want to make a non-spur one!
The problem with the plain stack vm appears to be to do with
CCodeGenerator>sizeOfIntegralCType: which complained about #void. In translating NewObjectMemory>fwdTableInit: the ‘sendNode args first’ is ‘self baseHeaderSize’ and the result of -
argType := self typeFor: sendNode args first self baseHeaderSize in: aTMethod.
is #void. That doesn’t seem quite right though since ObjectMemory>baseHeaderSIze is returning something - though I can’t help noticing that a method
"To support SmartSyntaxPluginCodeGenerator"
.. somehow looks a touch *odd*. Can’t quite put my finger on it…
If I do the obvious and ugly hack of making #baseHeaderSize just return 4, then the codegen completes. I wonder if it will make a working vm?
