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.

47b45d1d62 adjust the check! macro to accept AAPCS intrinsics 2017-02-07 23:07:51 -05:00
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)
```

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.

ee0aacf4be mul.rs: use wrapping_mul not plain 
rustc in debug mode with a plain multiplication will call @llvm.umul.with.overflow.* which may call the builtin resulting in infinite recursion.

3992ed1e7a CI: use a recent nightly 
- add #[no_mangle] to the panic_fmt lang item to adjust to changes in
the visibility algorithm

- adjust to changes in the layout of Cargo's target directory

- use a newer Xargo to reduce the build time of the sysroot (only core
is compiled as part of the sysroot now)
