2013-06-26rt: Release big stacks immediately after use to avoid holding on to them ↵Brian Anderson-42/+14
through yields This avoids the following pathological scenario that makes threadring OOM: 1) task calls C using fast_ffi, borrowing a big stack from the scheduler. 2) task returns from C and places the big stack on the task-local stack segment list 3) task calls further Rust functions that require growing the stack, and for this reuses the big stack 4) task yields, failing to return the big stack to the scheduler. 5) repeat 500+ times and OOM Conflicts: src/rt/rust_task.cpp
2013-06-23Remove unused TyDesc parameter from the glue functionsPhilipp Brüschweiler-1/+5
To remove the environment pointer, support for function pointers without an environment argument is needed (i.e. a fixed version of #6661).
2013-06-21Remove all #[cfg(stage0)]-protected codeJames Miller-8/+0
New snapshot means this can all go. Also removes places that have comments that say they are workarounds for stage0 errors.

2013-06-11Assert stk rather than checking nullRon Dahlgren-3/+3
Given that a big stack is never requested before allocating an initial stack segment, having a non-null stk member here is an invariant.
2013-06-09Check stk before dereferencingRon Dahlgren-1/+1
This commit fixes #7022 - I've added an additional check to ensure that stk is not null before dereferencing it to get it's next element, assigning NULL if it is itself NULL.

2013-04-21rt: Don't make memory_region depend on rust_envBrian Anderson-1/+1
I am going to use memory_region and boxed_region as the local heap in the new scheduler, for now at least, and I don't have a rust_env available.
