cec593c2aa Tweak testing and such: 
* Don't run `intrinsics` tests on thumb
* Disable `compiler_builtins` attribute on `feature = "gen-tests"`
* Disable mangling on `feature = "gen-tests"` instead of `cfg(test)`

6db18f6536 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.

bd4a416457 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

cd96f53050 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.

57deccf6de 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
3a4e6ce2f4 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)
```

70bda6dd1c 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.
