Again, in plain text mode:
Did something change with the compiler setup? The error here says gcc
6.0.0. however the version in the make.cross tool is 5.4.0, which is
strange. Fyi, We have binaries for 7.2.0 and 9.x which can be used.
Also our toolchain is all upstream as of last week.

I added a patch which disables gcc auto-inlining by '-fno-inline-functions
-fno-inline-small-functions -fno-inline-functions-called-once' (but default
option is false).
See series https://lkml.org/lkml/2018/5/9/213.
I am trying to make gcc happy for this corner case. Thanks!

Hi Atafford,
I do apologise for troubling you, we have updated the make.cross,
you could use "GCC_VERSION=6.0.0 make.cross ARCH=openrisc" to reproduce.
Best Regards,

Thanks, that explains it. I see that Du Changbin has addressed the actualy

Thanks, this looks like a really useful debug feature. Also, thanks for sending
the other patch to fix the build issue in openrisc.
