--- Comment #3 from Jeffrey A. Law <law at gcc dot gnu.org> ---
Note that we're seeing linux kernel build failures that may have the same
underlying problem:
./cc1 -O2 -mabi=64 main.i -quiet -I./
../drivers/base/power/main.c: In function ‘__device_suspend’:
../drivers/base/power/main.c:1606:12: error: invalid ‘PHI’ argument
_142
during GIMPLE pass: ifcvt
../drivers/base/power/main.c:1606:12: internal compiler error: tree check:
expected class ‘type’, have ‘exceptional’ (error_mark) in

I'll monitor this bug and re-test the kernel build once Andre has a potential
patch. If it turns out to be a distinct problem, then I'll open a new bug.
