Flexfloat

The code from the directory ../vendor/flexfloat comes from the open-source C/C++ library FlexFloat. The directory here implements a seperate Rust project (crate) which implements the FFI (Foreign Function Interface) bindings needed by Banshee (implemented in Rust) to include the C/C++ library FlexFloat.

Used configuration (see ../vendor/flexfloat/include/flexfloat_config.h):

• -DFLEXFLOAT_ON_DOUBLE
• -DFLEXFLOAT_NO_ROUNDING

Bindgen

Bindgen was used to generate the FFI file bindings.rs:

bindgen ../vendor/flexfloat/include/flexfloat.h -o src/bindings.rs

Manually applied changes to generated bindings.rs:

• commented out all functions which use longdouble: u128 for getting rid of warnings

Supported Instructions

The supported formats are defined in lib.rs.
