Hey Ferruh,

I'm facing this "max-inline-insns-single limit reached" problem now (while
trying to compile DPDK-16.04 on "3.18.34-20.el6.x86_64".

So, as you suggested, I changed the limit from 100 to 400, here:

dpdk-16.04/lib/librte_eal/linuxapp/igb_uio/Makefile

...and it worked!

The CentOS 6.8 "centos-xen-release" YUM/RPM package brings Linux 3.18 to
it, a new life for an old O.S... That's good...   :-)

Thanks!
Thiago
