/*
|
||||
* Closure implementation for Native Client.
|
||||
* Native Client imposes some interesting restrictions.
|
||||
*
|
||||
* First, we can only add new code to the code segment
|
||||
* through a special system call, and we have to pick the
|
||||
* maximum amount of code we're going to add that way
|
||||
* at link time (8l reserves 512 kB for us).
|
||||
*
|
||||
* Second, once we've added the code we can't ever
|
||||
* change it or delete it. If we want to garbage collect
|
||||
* the memory and then reuse it for another closure,
|
||||
* we have to do so without editing the code.
|
||||
*
|
||||
* To address both of these, we fill the code segment pieces
|
||||
* with very stylized closures. Each has the form given below
|
||||
* in the comments on the closasm array, with ** replaced by
|
||||
* a pointer to a single word of memory. The garbage collector
|
||||
* treats a pointer to such a closure as equivalent to the value
|
||||
* held in **. This tiled run of closures is called the closure array.
|
||||
*
|
||||
* The ptr points at a ClosureData structure, defined below,
|
||||
* which gives the function, arguments, and size for the
|
||||
* closuretramp function. The ClosureData structure has
|
||||
* in it a pointer to a ClosureFreeList structure holding the index
|
||||
* of the closure in the closure array (but not a pointer to it).
|
||||
* That structure has a finalizer: when the garbage collector
|
||||
* notices that the ClosureFreeList structure is not referenced
|
||||
* anymore, that means the closure is not referenced, so it
|
||||
* can be reused. To do that, the ClosureFreeList entry is put
|
||||
* onto an actual free list.
