This adds comparisons among the compiler-builtins function, system
functions if available, and optionally handwritten assembly.
These also help us identify inconsistencies between this crate and
system functions, which may otherwise go unnoticed if intrinsics get
lowered to inline operations rather than library calls.
* add 32 bit shift instructions to src/int/shift.rs
__ashlsi3
__ashrsi3
__lshrsi3
* add int_impl! for 16 bit numbers and large_int! for i32 and u32
* add tests in testcrate/build.rs
Adds generic conversion from a wider to a narrower IEEE-754
floating-point type.
Implement `__truncdfsf2` and `__truncdfsf2vfp` and associated test-cases.
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.
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.
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.
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!
