Hi Chris, there is a hint here how you can find out what gcc is actually using; you could try with and without the -march=native: http://en.chys.info/2010/04/what-exactly-marchnative-means/ On Mon, Jan 16, 2017 at 3:47 PM, Chris Trobridge wrote: > the initial args

Hello Chris, Probably unrelated, but yesterday my krogoth build failed on an Atom *host/build* system. I was just about to debug this when I saw your email. The configure stage of gmp-native decided to choose -march=k8 and -mtune=k8 -m64. I am debugging this currently. Maybe check if the

[yocto] Illegal Instruction Generate for Intel Atom

This arose building asterisk switching from 13.7 to 13.11+. The executable core dumps immediately with an illegal instruction instruction, which gdb reported as 'andn'. This is part of BMI1, which was introduced with Haswell. I am targeting a (32-bit) Z5xx Atom processor, which predates this
