Hi, list.
Today I noticed the following change in SHR:
http://git.openembedded.org/cgit.cgi/openembedded/commit/?id=1516588acd3c4b4dd4add71d06ab8ce0d1bafa02
(by Denis 'GNUtoo' Carikli<gnu...@no-log.org>) and decided to lmbench it.
Here are results: http://www.bsdmn.com/lmbench/unwind_summary.txt
You can see comparison of:
34def -> kernel with CONFIG_FRAME_POINTER
unwind -> kernel with CONFIG_ARM_UNWIND
default -> for reference, old debugging kernel
The unwind option provide clear benefit of 5%-10% in almost every area.
Nice spot Denis!
It does feel faster!
