28c57e7212 Add __ledf2vfp and __lesf2vfp 
Now that `73884ae` is in some nightly release We can add ledf2vfp/leds2vfp
and so these two functions be aliased to aeabi_fcmple/aeabi_dcmple on soft-float targets.

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

2cb290afa3 Fix __subsf3 and __subdf3 on x86 
Be sure to do not mix hard-float and soft-float calls.
Disassembled code show exactly this.
So replace add with an explicit call to __addsf3/__adddf3

This seems the root cause of some sporadic failures.

306764b091 Fix issue extending f32::MIN/MAX to f64 and improve testcrate. 
I was able to trigger an issue extending f32::MAX or f32::MIN to a f64.
Issue was not triggered by `testcrate` mainly because f32::MAX/MIN are
not in the list of special values to generate.

This PR fix the issue and improve `testcrate` adding MAX/MIN/MIN_POSITIVE
in the list of special values.

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.

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.

f42b9e0bad __[mul/div]sf3vfp and __[mul/div]df3vfp only on ARM 2018-01-30 18:48:20 +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

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

6adcc9e9cb comparesf2/comparedf2: use i32 instead of bool for return type. 
Note that this changes semantics:
    pub extern "C" fn __eqsf2(a: f32, b: f32) -> bool {
        cmp(a, b).to_le_abi() != 0
    }

is not the same as

    pub extern "C" fn __eqsf2(a: f32, b: f32) -> i32 {
        cmp(a, b).to_le_abi()
    }

However, compiler-rt does the latter, so this is actually
an improvement.
