- Subject: [PATCH 0/5] New double precision exp, exp2, log, log2 and pow functions
The implementations are based on code from
https://github.com/ARM-software/optimized-routines
and provided here under 3 clause BSD license.
Tested on aarch64 and arm targets.
(I'll reply with git format-patch attached because git
send email does not work for me and thunderbird mangles
things if i inline).
Szabolcs Nagy (5):
Use uint32_t sign argument to math error functions
New exp and exp2 implementations
New log implementation
New log2 implementation
New pow implementation
