OpenACC 'nohost' clause: harmonize
'libgomp.oacc-{c-c++-common,fortran}/routine-nohost-1.*'
The test case 'libgomp.oacc-fortran/routine-nohost-1.f90' added in 2021
commit a61f6afbee370785cf091fe46e2e022748528307 "OpenACC 'nohost' clause"
was
dependend on inlining being enabled, and otherwise ('-fno-inline') failed to
optimize/link:
/tmp/ccb2hsPd.o: In function `MAIN__._omp_fn.0':
routine-nohost-1.f90:(.text+0xf4): undefined reference to `fact_nohost_'
However, as of recent commit 3269a722b7a03613e9c4e2862bc5088c4a17cc11
"Fortran: Use OpenACC's acc_on_device builtin, fix OpenMP'
__builtin_is_initial_device",
we're now properly handling OpenACC/Fortran 'acc_on_device', and may specify
'-fno-inline', like done in 'libgomp.oacc-c-c++-common/routine-nohost-1.c'.
libgomp/
* testsuite/libgomp.oacc-fortran/routine-nohost-1.f90: Add
'-fno-inline'.
