This reverts commit baab4fd89c.

Paolo Teti baab4fd89c Conversion from a wider to a narrower IEEE-754 floating-point type 
Adds generic conversion from a wider to a narrower IEEE-754
floating-point type.

Implement `__truncdfsf2` and `__truncdfsf2vfp` and associated test-cases.

Paolo Teti 59353afa10 Remove superfluous cc flags 
Latest `cc-rs` already manage all arm/thumb flags, so We can
safely remove this piece of code.

Alex Crichton 0703bfa725 Fix some `use_c_shim_if` directives 
This was an accidental regression introduced in #252 by removing compilation of
C files without adjusting the `#[use_c_shim_if]` directives. This restores the
compilation of the assembly files and updates the `#[use_c_shim_if]` directives.

Yu Ding bf370326cf Fix symbol collision caused by floatdisf 
[PR #234](https://github.com/rust-lang-nursery/compiler-builtins/pull/234) added floatdisf implementation in rust and removed floatdisf.c from build.rs. However the removal is in-complete. In x86_64+!msvc environment, the symbol floatdisf would be generated twice. Bugs found in Redox OS issue [#1195](https://gitlab.redox-os.org/redox-os/redox/issues/1195) and Mesalink travis [log](https://travis-ci.org/mesalock-linux/mesalink/jobs/412928048) at line 738. This patch fixes it by removing floatdisf.c from this environment.

Alex Crichton 5d370bb352 Don't build multc3 on AArch64 MSVC 
Apparently it doesn't compile due to an odd compiler error! This intrinsic has
to do with complex arithmetic anyway and we shouldn't need it.

compiler_rt is provided by default on OpenBSD, so use it instead of

Paolo Teti 280012b1df Fix thumbv6m build (feature=c) 
1. Avoid undefined references as:
   undefined reference to `__modsi3'
   undefined reference to `__umodsi3'

2. We can't remove assembly implementations that are not in the list

Paolo Teti e7bf03019c Collection of VFP intrinsics 
Nothing really exciting here. LLVM on hard-float target use native instructions
for all listed VFP intrinsics and so resulting implementation is really trivial.

Implemented intrinsics:

 __gesf2vfp
 __gedf2vfp
 __gtsf2vfp
 __gtdf2vfp
 __ltsf2vfp
 __ltdf2vfp
 __nesf2vfp
 __nedf2vfp
 __eqsf2vfp
 __eqdf2vfp
 __extendsfdf2vfp

Paolo Teti 45f924ece5 Add generic conversion from a narrower to a wider FP type 
Add `extend` module to implement conversion from a narrower to a wider
floating-point type.

This implementation is only intended to support *widening* operations.
Module to convert a *narrower* floating-point will be added in the future.

Paolo Teti 13db8bf436 Add support for sub*f3vfp and add*f3vfp 
As done before for mul and div let's use extern "C" to generate `"aapcs"`
or `"aapcs-vfp"` depending on target configuration.

Alex Crichton 2a13475197 Simplify how testing is done 
All tests are moved to a separate crate in this repository to enable features by
default. Additionally the test generation is moved to a seprate build script and
simplified to reduce the amount of boilerplate needed per test.

Overall this should still be testing everything, just in a different location!

Paolo Teti 9e04723812 Add test cases for Mul[s/d]f3vfp and Div[s/d]f3vfp 
for ARM targets only
 2018-01-30 20:15:37 +01:00
Paolo Teti 8f018562ca Add support for mul[s/d]f3vfp and div[s/d]f3vfp 
Here using `"C"` the compiler will use `"aapcs"` or `"aapcs-vfp"`
depending on target configuration.

Of course this translates in a call to `__aeabi_fdiv` / `__aeabi_fmul`
on non-HF targets.

On `eabi` targets with +vfpv2/vfpv3 LLVM generate:

   vmov	s0, r1
   vmov	s2, r0
   vdiv.f32	s0, s2, s0
   vmov	r0, s0
   bx	lr

On `eabihf` targets with +vfpv3-d16/d32/f32 +fp-only-sp LLVM generate:

  vdiv.f32	s0, s0, s1
  bx	lr

That's exactly what We need for [div/mul][s/d]f3vfp.S

Alex Crichton 7d5fb94560 Fix some typos/bugs with float comparison intrinsics 
* I believe `__gtdf2` erroneously used `f32` instead of `f64`
* Most of these needed `#[arm_aeabi_alias]` to ensure they're correctly called
  through the alias
* Some existing aliases were corrected with the right names

Paolo Teti a75a49990c Skip aeabi_cdcmp and aeabi_cfcmp on big-endian targets 
First of all aeabi_cdcmp and aeabi_cfcmp are never called LLVM.
Second are little-endian only, so build fail on big-endian targets.
Temporally workaround: exclude these files for big-endian targets.

Alex Crichton 45cd956acc Prepare this crate for more wasm32 compatibility 
This commit prepares the build script for a wasm32 target that doesn't use
Emcripten, notably forcing the `mem` feature to get activated and forcibly
ignoring the `c` feature, even if activated, for the wasm32 target.
