Wilfried Chauveau 293fef5ebe impl (unsigned/signed) int to single/double precision float conversion based on llvm algorithms. 2017-03-06 11:55:57 -05:00
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.

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)
```

i128 intrinsics

Adds i128 intrinsics.

Note that this PR doesn't do float intrinsics, due to the missing presence of macros, those are however still required in order for rustc to switch to this crate.

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.

mul.rs: use wrapping_mul to avoid infinite recursion

rustc in debug mode with a plain multiplication will call @llvm.umul.with.overflow.* which may call the builtin resulting in infinite recursion.

Fixes #127.

Cc @nezza this should be the fix you can try. Note I made this patch in github's web Ui so it's completely untested.
