| * Unify instruction namingLars Knoll2017-08-281-333/+333
| | | | | | | | | | | | | | | | Simplify the naming conventions, so that both the instruction struct and enum start with upper case letters. Change-Id: I60c5a95d729e0b68b5a40f7db0e8f90be5938032 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>
| * Change offsets to be integer basedLars Knoll2017-08-281-18/+18
| | | | | | | | | | | | | | | | | | This is big enough for generated bytecode, and gives more uniform sizing in our instructions (everything's an int), that will simplify moving over to a compressed instruction stream.

| * Don't use a return value register for regular functionsErik Verbruggen2017-08-181-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | don't use the return value register for normal functions anymore. It's still needed for eval code and qml bindings that have an implicit return value, as the accumulator gets clobbered too easily in those cases. Also get rid of the exit block we used to generate. Adjust the control flow handlers to correctly unwind. This required adding some jump instructions that left the accumulator untouched (as it now holds the return value) and using those in handlers.

| * Refactor context handlingLars Knoll2017-08-101-9/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the push/pop context instructions to not modify the JS stack anymore, as that can cause conflicts with the VME (and was an ugly hack in any case). Instead, these instructions not return the old context, that is then stored in a temporary. Get rid of Engine::current and Engine::currentContext. The StackFrame structures do now contain the only and authoritive data. This finally gives us a nice setup where we create and destroy frames on the stack when entering/leaving functions.
