Subject: new decimal conversion - seeking testers
Date: Fri, 13 Mar 2015 00:09:19 +0100 [thread overview]
Message-ID: <87fv99x17k.fsf@rasmusvillemoes.dk> (raw)
Hi,
I've proposed a new implementation of decimal conversion for
lib/vsprintf.c; see
<http://thread.gmane.org/gmane.linux.kernel/1892035/focus=1905478>.
Benchmarking so far shows 25-50% (depending on distribution of input
numbers) improvement on x86_64 and 10-30% on various 32 bit platforms.
Since the new code plays a little endianness game I would really
appreciate it if someone here would run the test and verification code
on ppc.
The code is on github, https://github.com/Villemoes/dec, and it should
be as simple as
git clone https://github.com/Villemoes/dec.git
cd dec
make
./test # benchmark
./verify # correctness
though I can't blame you if you want to inspect the code before
compiling and running something some stranger asks you to download :-)
See also the README file.
If 'make' doesn't work out-of-the-box, I'd also like to hear from you.
Thanks,
Rasmus
