Subject: [PATCH] Speed up libm on MIPS
Date: Thu, 19 Sep 2013 22:58:00 -0000	[thread overview]
Message-ID: <1379631395.5770.445.camel@ubuntu-sellcey> (raw)

[-- Attachment #1: Type: text/plain, Size: 1809 bytes --]

This patch defines various inline routines and macros used by the math
library in order to speed up libm on MIPS.  It does not affect
soft-float builds but for hard-float builds 'make bench' shows a
speed-up.  With an o32 little-endian glibc, sin() went from 27792.6
iter/s to 31293.6 iter/s.  On n32 it went from 32955.2 to 36179.7 and on
n64 from 33074.7 to 36242. exp() went from 45742.4 to 56511.2 on o32 and
pow() went from 19008.8 to 20508.7.  I have attached the original and
new bench.out files for o32, n32, and n64 ABIs in case you want to see
more of the data.  These are all little-endian hard-float runs.

I ran 'make check' and 'make bench' using the o32, n32, and n64 ABIs
with big and little endian and with hard and soft float to verify there
were no failures.  I did run into an unrelated problem that is being
fixed ( but
there were no other failures except the expected ones for MIPS.

OK for checkin?
