Arm Optimized Routines
----------------------
This repository contains implementations of library functions
provided by Arm. The outbound license is available under a dual
license, at the user’s election, as reflected in the LICENSE file.
Contributions to this project are accepted, but Contributors have
to sign an Assignment Agreement, please follow the instructions in
contributor-agreement.pdf. This is needed so upstreaming code
to projects that require copyright assignment is possible. Further
contribution requirements are documented in README.contributors of
the appropriate subdirectory.
Regular quarterly releases are tagged as vYY.MM, the latest
release is v23.01.
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.
networking/ - networking subproject sources.
networking/include/ - networking library public headers.
networking/test/ - networking test and benchmark related sources.
string/ - string routines subproject sources.
string/include/ - string library public headers.
string/test/ - string test and benchmark related sources.
pl/... - separately maintained performance library code.
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.
