Module elliptic_curve::util

Arithmetic helper functions designed for efficient LLVM lowering.

These functions are intended for supporting arithmetic on field elements modeled as multiple “limbs” (e.g. carry chains).

Functions

adc32

Computes a + b + carry, returning the result along with the new carry. 32-bit version.

adc64

Computes a + b + carry, returning the result along with the new carry. 64-bit version.

mac32

Computes a + (b * c) + carry, returning the result along with the new carry. 32-bit version.

mac64

Computes a + (b * c) + carry, returning the result along with the new carry. 64-bit version.

sbb32

Computes a - (b + borrow), returning the result along with the new borrow. 32-bit version.

sbb64

Computes a - (b + borrow), returning the result along with the new borrow. 64-bit version.
