hosts.

9e65060184 Add __truncdfsf2 intrinsic 
This adds the truncdfsf2 intrinsic and a corresponding fuzz test case. The
implementation of trunc is generic to make it easy to add truncdfhs2 and
truncsfhf2 if rust ever gets `f16` support.

floating-point type.

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

20de84d127 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.

b2aea631fe 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

0af69177f9 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.

97e6b3712a 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.
 2018-02-04 18:34:31 +01:00
Paolo Teti
9a4e458b48 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

24175dd6ca Implement comparesf2/comparedf2 intrinsics. 2017-12-28 03:45:32 +00:00
whitequark
c329f6ef75 comparesf2/comparedf2 are called on soft-float targets. 
E.g. take a look at the assembly output for:

  pub fn comparesf2(a: f32, b: f32) -> bool { a > b }
  pub fn comparedf2(a: f64, b: f64) -> bool { a > b }

which will include calls to __gtsf2 and __gtdf2.
