2013-11-18rt: Namespace all C functions under rust_Brian Anderson-10/+10
2013-11-06Fixes for compilation to iOS:kud1ing-2/+8
- remove /usr/include from the include path since the iOS SDK provides the correct version - `_NSGetEnviron()` is private and not available on iOS - `.align` without an argument is not allowed with the Apple tools. 2^2 should be the default alignment - ignore error messages for XCode < 5 - pass include path to libuv
2013-10-22Fix unwinding on OS X 10.9.Mark Rowe-3/+21
OS X 10.9's linker has a bug that results in it failing to preserve DWARF unwind information when passed the -no_compact_unwind flag. This flag is passed on OS X because the unwind information for __morestack cannot be represented by the compact unwind format. We can work around this problem by using a more targeted approach to disabling compact unwind information. The OS X linker looks for a particular pattern in the DWARF unwind information and will not attempt to convert the unwind information to the compact format. The pattern in question is the return address register being saved twice to the same location. Fixes #6849.
2013-10-19Use __morestack to detect stack overflowAlex Crichton-1407/+56
This commit resumes management of the stack boundaries and limits when switching between tasks. This additionally leverages the __morestack function to run code on "stack overflow". The current behavior is to abort the process, but this is probably not the best behavior in the long term (for deails, see the comment I wrote up in the stack exhaustion routine).
2013-08-26Support Win64 context switchingklutzy-9/+75
This patch saves and restores win64's nonvolatile registers. This patch also saves stack information of thread environment block (TEB), which is at %gs:0x08 and %gs:0x10.
2013-08-26rt: Add {get,record}_sp_limit on Win64klutzy-0/+8
Uses ArbitraryUserPointer area at gs:0x28.
2013-08-26rt: Remove leading underscore on Win64klutzy-3/+6
Win64 convention does not use underscore.

2013-05-17auto merge of #6249 : crabtw/rust/arm, r=brsonbors-0/+8
It uses the private field of TCB head to store stack limit. I tested on my Raspberry PI. A simple hello world program ran without any problem. However, for a more complex program, it segfaulted as #6231.

2013-04-18auto merge of #5418 : luqmana/rust/stack-float, r=brsonbors-19/+3
Like I commented in #2043, I can't reproduce the weirdness from #1388 on either mac or linux (x84_64) and pushing to try gives all green. That's 128 less bytes to have to keep in the stack for every call to __morestack.

Closes #5643 This also removes the need to pass noexecstack to gcc, but that wasn't actually working anymore.
2013-03-25auto merge of #5424 : luqmana/rust/inline-rt, r=brsonbors-112/+200
As per #2521. Inlining seems to improve performance slightly: Inlined Not Inlined x86: 13.5482 14.4112 x86_64: 17.4712 18.0696 (Average of 5 runs timed with `time`) ```Rust fn foo() -> int { int::from_str(~"28098").unwrap() } fn main() { for 1000000.times { foo(); foo(); foo(); foo(); foo(); } } ``` All run on: Linux 3.2.0-0.bpo.4-amd64 #1 SMP Debian 3.2.35-2~bpo60+1 x86_64 GNU/Linux The MIPS and ARM bits I didn't inline since I'm not as familiar with them and I also can't test them. All green on try.
