Keith Packard, active Debian developer, leader of the X.Org project and creator of many X extensions, including XRender, XComposite and XRandR, release of the standard C library , developed for use on embedded devices with a limited amount of permanent storage and RAM. During development, part of the code was borrowed from the library from the Cygwin project and , developed for Atmel AVR microcontrollers. PicoLibc Code under BSD license. Library assembly is supported for ARM (32-bit), i386, RISC-V, x86_64 and PowerPC architectures.
Initially, the project was developed under the name βnewlib-nanoβ and was aimed at reworking some of the resource-intensive functions of Newlib, which were problematic to use on embedded devices with little RAM. For example, the stdio functions have been replaced with a compact version from the avrlibc library. The code has also been cleaned of non-BSD-licensed components not used in the embedded build. A simplified version of the initialization code (crt0) has been added, and the implementation of local threads has been moved from 'struct _reent' to the TLS mechanism (). The Meson toolkit is used for assembly.
In the new release:
- Added the ability to build using compiler .
- Added support for the Clang compiler.
- The behavior of the 'gamma' function has been brought into line with the behavior of Glibc.
- The nano-malloc implementation ensures that returned memory is cleared.
- Improved performance of nano-realloc, especially when merging free blocks and expanding heap size.
- Added a set of tests to check the correct operation of malloc.
- Improved support for the Windows platform and added the ability to build using the mingw toolkit.
- On ARM systems, if available, the TLS (Thread-Local Storage) hardware register is enabled.
