Severity: normal
Dear Maintainer,
Building the 3.0-based smdk4412 kernel[1] with the arm-none-eabi
toolchain from Stretch fails with an internal compiler error:
/home/wolfi/6.0-romsrc/kernel/samsung/smdk4412/mm/vmscan.c: In function
'shrink_page_list':

The kernel builds fine using the gcc-arm-none-eabi version from
Jessie. A workaround is to disable optimization for the function the
compiler fails to optimize[2].
Thanks,
