Arm Optimized Routines

----------------------

|
This repository contains implementations of math library functions

relicensing and copyright assignment to the FSF is possible later).

|
Source code layout:
|
|
auxiliary/ - design tools.
|
build/ - build directory (created by make).
|
math/ - math library source.
|
math/include/ - math library public headers.
|
math/single/ - code for cpu with only single precision support.
|
test/ - test related source.
|
test/rtest/ - test generator (requires mpfr and mpc).
|
test/testcases/ - test cases.
|
|
The steps to build the library 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
|
|
The test system requires libmpfr and libmpc.
|
|
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.
|
|
The script "remez.jl" was used to generate some of the coefficients
|
(see comments in the code).
