d86a32bbb2 fix mips stack alignment 2013-05-21 11:58:30 +08:00

d68c0279ea auto merge of #6249 : crabtw/rust/arm, r=brson 
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.

2a86485277 auto merge of #5418 : luqmana/rust/stack-float, r=brson 
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.

26fc76acb6 rt/arch/arm: fix syntax used for noexec stack 2013-04-01 00:31:22 -04:00
Daniel Micay
c0be7df5de mark the assembly object stacks as non-executable 
Closes #5643

This also removes the need to pass noexecstack to gcc, but that wasn't
actually working anymore.

6d4499ce4d auto merge of #5424 : luqmana/rust/inline-rt, r=brson 
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.
