| Arm Optimized Routines |
| ---------------------- |
| |
| This repository contains implementations of library functions |
| provided by Arm under MIT License (See LICENSE). Contributions |
| to this project are accepted, but the terms will need negotiation (so |
| relicensing and copyright assignment to the FSF is possible later). |
| |
| Regular quarterly releases are tagged as vYY.MM (e.g. v19.11). |
| |
| Source code layout: |
| |
| build/ - build directory (created by make). |
| math/ - math subproject sources. |
| math/include/ - math library public headers. |
| math/test/ - math test and benchmark related sources. |
| math/tools/ - tools used for designing the algorithms. |
| string/ - string routines subproject sources. |
| string/include/ - string library public headers. |
| string/test/ - string test and benchmark related sources. |
| |
| The steps to build the target libraries and run the tests: |
| |
| cp config.mk.dist config.mk |
| # edit config.mk if necessary ... |
| make |
| make check |
| |
| Or building outside of the source directory: |
| |
| ln -s path/to/src/Makefile Makefile |
| cp path/to/src/config.mk.dist config.mk |
| echo 'srcdir = path/to/src' >> config.mk |
| # further edits to config.mk |
| make |
| make check |
| |
| Or building and testing the math subproject only: |
| |
| make all-math |
| make check-math |
| |
| The test system requires libmpfr and libmpc. |
| For example on debian linux they can be installed as: |
| |
| sudo apt-get install libmpfr-dev libmpc-dev |
| |
| For cross build, CROSS_COMPILE should be set in config.mk and EMULATOR |
| should be set for cross testing (e.g. using qemu-user or remote access |
| to a target machine), see the examples in config.mk.dist. |
