[LLVMdev] Proposal: stack/context switching within a thread
I created a wiki at http://code.google.com/p/llvm-stack-switch/
Right now I just copied and formatted the document as-is... I'll go
back over it with your comments in mind soon. One more question,
which you can answer here or there:
> Point 4 is a bit confusing. Normally, it's fine for a thread to share

[LLVMdev] [RFC] Parallelization metadata and intrinsics in LLVM (for OpenMP, etc.)
...n the frontend (please read this in conjunction with [1]):
Parallel regions can be lowered as a parallel_map with
@llvm.num_threads as the limit.
```
#pragma PARALLEL
block
```
desugars to
```
@llvm.parallel_map(num_threads, block_closure, shared_closure)
...
void block_closure(i32 tid, i8* shared_vars) {
block
}
```
Reductions are handled by a parallel_map followed by a regular
reduction loop (exactly as in Hal's proposal).
Serial blocks reduce to a block conditional on the index inside the
function being parallelly mapped.
We lower critical and ordered regions into calls to `sync_region...
