Paolo Teti 280012b1df Fix thumbv6m build (feature=c)
1. Avoid undefined references as:
   undefined reference to `__modsi3'
   undefined reference to `__umodsi3'

2. We can't remove assembly implementations that are not in the list

Alex Crichton a6f7dfd2fd Fix nightly CI
Currently we're getting lots of errors about duplicate lang items so deal with
this by `#[cfg_attr]`'ing off the lang item attribute in tests.

Alex Crichton 681aaa914d Use the Rust implementation of udivsi3 on ARM
Although compiler-rt presumably has a more optimized implementation written in
assembly, it appears buggy for whatever reason, causing #173.

For now let's see if integration into rust-lang/rust will work with the
Rust-defined implementation!

Alex Crichton 7de57cd4f9 Handle aeabi aliasing
Objects in compiler-rt may have two symbols, so this makes sure that we don't
bring in those objects by accident by defining the aliases ourselves.

Alex Crichton 2f2bb32e40 Use traits instead of macros for shift intrinsics
This is an attempt to tidy up the definition of intrinsics by making them more
rust-like at the definition site and using traits instead of macros for the
definition. Additionally the helper macro, `intrinsics!`, now fills in a
definition for #[cfg]'d off intrinsics when compiling with C code

Jorge Aparicio 644a1c9ac9 fix infinite recursion in divmoddi4 / mulodi4
on ARMv7-M processors, divmoddi4 was calling mulodi4 and mulodi4 was calling
divmoddi4 leading to infinite recursion. This commit breaks the cycle by using
wrapping multiplication in divmoddi4.

Jorge Aparicio 57085be2ea ARM: keep some non-aeabi symbols around
- multi3: there's no aeabi equivalent
- divmod{s,d}i4: these are directly called by __aeabi_{l,i}divmod
- add{s,d}f3: required by the C sub{s,d}f3 implementation

but make sure they also use the AAPCS calling convention
2017-02-07 14:28:02 -05:00
Jorge Aparicio dfa7b161aa use AAPCS calling convention on all aeabi intrinsics
also, on ARM, inline(always) the actual implementation of the intrinsics so we
end with code like this:

```
00000000 <__aeabi_dadd>:
    (implementation here)
```

instead of "trampolines" like this:

```
00000000 <__aeabi_dadd>:
    (shuffle registers)
    (call __adddf3)

00000000 <__adddf3>:
    (implementation here)
```

closes #116

est31 37d349015e Disable quickcheck tests on mips
Two reasons:
    * the C versions __divti3 and __modti3 are apparently broken,
      at least when used in quickcheck. They change their own arguments.
    * compiler_rt's support for mips is disabled already on clang [1].
      Its desireable to support working "cargo test" on that compiler
      as well, and not greet the tester with linker errors.
