--- Comment #2 from John Donners <john.donners at atos dot net> ---
thanks for reviewing this. Indeed, the compiler bug does not occur when using
the intelmicemul target:

gfortran -foffload=x86_64-intelmicemul-linux-gnu -g  -fopenmp -O3 bla.f90
/lib/../lib64/crt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
/tmp/ccfY1ov8.o: In function `therm_ice_':
/home_nfs_robin_ib/bdonnersj/tmp/bla.f90:61: undefined reference to `budget_'
/home_nfs_robin_ib/bdonnersj/tmp/bla.f90:61: undefined reference to `budget_'
collect2: error: ld returned 1 exit status

but it does occur for the nvptx-none target:

$ gfortran -foffload=nvptx-none -g  -fopenmp -O3 bla.f90
during GIMPLE pass: ompdevlow
bla.f90: In function ‘thermodynamics_._omp_fn.1’:

I do not know what happens for the amdgcn-amdhsa target.
