2013-04-17auto merge of #5726 : brson/rust/struct-return, r=brsonbors-2/+0
r? @nikomatsakis This doesn't completely fix the x86 ABI for structs, but it does fix some cases. On linux, structs appear to be returned correctly now. On windows, structs are only returned by pointer when they are greater than 8 bytes. That scenario works now. In the case where the struct is less than 8 bytes our generated code looks peculiar. When returning a pair of u16, C packs both variables into %eax to return them. Our generated code though expects to find one of the pair in %ax and the other in %dx. Similar for u8. I haven't looked into it yet. There appears to also be struct passing problems on linux, where my `extern-pass-TwoU8s` and `extern-pass-TwoU16s` tests are failing.
2013-04-17rustc: Use an out pointer to return structs in x86 C ABI. #5347Brian Anderson-2/+0
This Adds a bunch of tests for passing and returning structs of various sizes to C. It fixes the struct return rules on unix, and on windows for structs of size > 8 bytes. Struct passing on unix for structs under a certain size appears to still be broken.

2013-04-15core::rt: Narrow down the unsafety of the thread-local schedulerBrian Anderson-47/+47
Only when borrowing the I/O implementation do we need unsafety
2013-04-15core::rt: Restructure context switches to take ownership of the SchedulerBrian Anderson-62/+94
In order to do a context switch you have to give up ownership of the scheduler, effectively passing it to the next execution context. This could help avoid some situations here tasks retain unsafe pointers to schedulers between context switches, across which they may have changed threads. There are still a number of uses of unsafe scheduler pointers.
2013-04-15core::rt: Make Scheduler::unsafe_local return a fabricated region pointerBrian Anderson-247/+228
Instead of taking a closure. It's unsafe either way. Rename it to unsafe_local_borrow.

These would not be threadsafe
2013-04-14core::rt: Clean up the thread-local scheduler codeBrian Anderson-74/+79
Remove the ThreadLocalScheduler type in favor of functions. Move everything into the sched::local module.

2013-04-14core::rt: Schedulers only need a single cleanup_job at a timeBrian Anderson-31/+31
Each context switch has up to one cleanup job and it is always executed immediately after the context switch.

2013-04-14core::rt: Restructure task_from_last_cleanup_job to borrow correctlyBrian Anderson-48/+63
We need a number of mutable references to contexts so name it `get_contexts` and return a tuple of all of them.

2013-03-29Add AbiSet and integrate it into the AST.Niko Matsakis-1/+1
I believe this patch incorporates all expected syntax changes from extern function reform (#3678). You can now write things like: extern "<abi>" fn foo(s: S) -> T { ... } extern "<abi>" mod { ... } extern "<abi>" fn(S) -> T The ABI for foreign functions is taken from this syntax (rather than from an annotation). We support the full ABI specification I described on the mailing list. The correct ABI is chosen based on the target architecture. Calls by pointer to C functions are not yet supported, and the Rust type of crust fns is still *u8.

2013-03-29auto merge of #5570 : alexcrichton/rust/fix-unused-imports, r=sanxiynbors-12/+7
Before it wouldn't warn about unused imports in the list if something in the list was used. These commits fix that case, add a test, and remove all unused imports in lists of imports throughout the compiler.
