So after *really* struggling I profiled Holger's code.
I put results in attachment with version 3427 and version 3684 of the VM.
Holger said the code is not open-source, so if you want more information about the code ask him (or I guess I can answer if it's for a specific method).
The code execution is well spread around the methods. It's difficult to conclude.
It seems (I say, it seems) that the execution spend more time in recent versions in PICs.
It could be that the machine code produced there is different because of:
- the abstraction with 32/64 bits
- the abstraction over literals for ARM
- the design changes, if I understood correctly now PIC are created from a prototype.
Now it could be something else.
I have no time to investigate further right now. Maybe we should try to generate PICs in 3427 and 3684 and check if the machine code is different. Which VMMaker version is 3427 ?
