Hi,

-free has been enabled by default for -O2 and above on AArch64 a while 
ago.  This patch updates the relevant part of user manual to reflect the 
fact.

OK for stage-4?

Thanks,
Yufeng

Looks okay to me, that I'd prefer it to be approved by a target
maintainer -- AArch64 here.

Thanks.  Patch has been committed to the trunk.  Is it OK for 
gcc-4_9-branch?

Thanks,
