[LLVMdev] Position-independent stacks
Hi,
I am toying with an idea of having LLVM generate code that has
position-independent stacks. This would be a very useful property for
implementing all sorts of micro-thread libraries (I am thinking something
similar to Python greenlets <http://stackoverflow.com/a/17447308>), because
you'd be able to easily save threadlet state from one OS thread and later
restore it into another.

[LLVMdev] Position-independent stacks
...eration still create machine
code that takes and stores (in a register perhaps) an address of something
on the stack, even if not semantically visible to the programmer? Can
this somehow be detected?
- Can frame pointers be disabled on all architectures? If not, is the
frame pointer chain always walkable?
- Can frame pointers be disabled on a per-function basis? (this is in case
not the whole program's stacks need to be made relocatable).
