5.2.4. C Standard Library—newlib

The HAL integrates the ANSI C standard library in its runtime environment. The HAL uses newlib, an open-source implementation of the C standard library. newlib is a C library for use on embedded systems, making it a perfect match for the HAL and the Nios V processor. newlib licensing does not require you to release your source code or pay royalties for projects based on newlib.
Note: For Nios® V processor, newlib is upgraded to version 1.18.
