==================== Summary ====================
Name: VMMaker.oscog-eem.1565
Author: eem
Time: 7 December 2015, 5:25:51.389 pm
UUID: 98c5bc39-e721-42ba-9bac-5b1dbfc0963b
Ancestors: VMMaker.oscog-EstebanLorenzano.1564
x64 Cogit:
Half-fix StackToRegisterMappingCogit>>genDoubleArithmetic:preOpCheck: so as not to produce a bogus value when faced with a smallFloat arg. With this fix the simulator generates output in an emergency evaluator complaining of a primitive failure (which wouldn't fail wityh conversion of smallFloat args). (Still have to define it for SimpleStackBasedCogit).
Implement the default do-nothing maybeGenConvertIfSmallFloatIn:into:andJumpTo: which will soon provide the relevant conversion.
Rename genLoadHeader:intoNewInstance:using: to genStoreHeader:intoNewInstance:using:, which is what it does.
Eliminate the unnecessary nop when MoveCqR uses MoveCwR to generate a long constant.
