Hi!

Weird. Everything works on my arm chromebook (though I run debian sid). Please 
list the following to help me:

* cat /proc/cpuinfo

* your dpkg arch: dpkg --version and dpkg --print-architecture

* and your version of gperftools

* what is your ubuntu version

* also please double-check that c++ is g++. I.e. by running c++ -v

Thanks. I'll get myself ubuntu 14.04 and try it out. I.e. my box is also armhf 
and arm7l.

This looks very weird. Like inline assembly is not recognized.

The issue is not in code but in the way you configure it.

When I change --std=c++11 to --std=gnu++11 it works. What is the purpose of 
trying to build it in --std=c++11 ?

GoogleCodeExporter commented 9 years ago 
hm. it looks like __SYS_REG_LIST macro behaves differently in c++11 and gnu++11 
mode. Avoid -std=c++11 for now

Specifically I've verified that this:

#define __SYS_REG_LIST(regs...) [sysreg] "r" (__sysreg) , ##regs

expands to: [sysreg] "r" (__sysreg)
(no trailing comma) when regs are empty in normal mode

and to: [sysreg] "r" (__sysreg) ,
(trailing comma) when regs are empty in c++11 mode
