Creating a virtual machine: stack, regs alloc & other problems
...nguage specific knowledge.
Hmm.. this sounds interesting. thanks.
So, if I understand correctly, if we need to allocate a VM stack frame, the idea is to create
enough allocas, then store there values which need to be in the VM frame?
But how can it survive optimizing passes?
(I assume that we did stackload before and esp points to VM stack)
Could you please explain more?
