2011-07-07Make moving of temporaries do the right thing, use it to optimizeMarijn Haverbeke-135/+174
This adds support for dropping cleanups for temporary values when they are moved somewhere else. It then adds wraps most copy operations (return, put in data structure, box, etc) in a way that will fall back to a move when it is safe. This saves a lot of taking/dropping, shaving over a megabyte off the stage2/rustc binary size. In some cases, most notably function returns, we could detect that the returned value is a local variable, and can thus be safely moved even though it is not a temporary. This will require putting some more information in lvals. I did not yet handle function arguments, since the logic for passing them looked too convoluted to touch. I'll probably try that in the near future, since it's bound to be a big win.
2011-07-07Improve handling of move and swap by alias checkerMarijn Haverbeke-10/+24
Closes issue #541. Closes issue #591
2011-07-06Allocate rust_ivec buffers out of the kernel poolRob Arnold-6/+26
The duplication of upcalls is due to the fact that the runtime is shared between stage0/rustc and stage1/rustc. Once snapshots are updated, they should be de-duplicated.
