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.

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
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

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.
