Jorge Aparicio 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)
```

Alex Crichton 8e161a791a Expand and refactor teting infrastructure
This commit moves over most of the testing infrastructure to in-tree docker
images that are all dispatched to from Travis (no other test configuration).
This allows versioning modifications to the test infrastructure as well as the
code itself. Additionally separate docker images allows for easy modification of
one without worrying about tampering of others as well as easy addition of new
targets by simply adding a new `Dockerfile`.

Additionally this commit bundles the master version of the `compiler-rt` source
repository from `llvm-mirror/compiler-rt` to test against. The compiler-rt
library itself is compiled as a `cdylib` which is then dynamically located at
runtime and we look for symbols in. There's a few hoops here, but they currently
get the job done.

All tests now execute against both gcc_s and compiler-rt, and this
testing strategy is now all hidden behind a macro as well (refactoring
all existing tests along the way).

Jorge Aparicio 384c48ce9b don't test always against gcc_s
instead test half of the time against gcc_s and the other half test
against the native operation (\*).

(\*) Not all the targets have available a native version of the
intrinsics under test. On those targets we'll end up testing our
implementation against itself half of the time. This is not much of a
problem because we do several quickcheck runs per intrinsic.

Jorge Aparicio 337bd7e209 armhf: don't compare our impls against gcc_s 2016-09-21 21:14:38 -05:00
Jorge Aparicio 9493c37455 test our implementations against gcc_s
if it exposes the same intrinsics that we implement -- gcc_s doesn't
implement all the intrinsics for all the architectures.
