Bug ID: 82250
Summary: Fortran OpenACC acc_on_device early folding
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Keywords: openacc
Severity: enhancement
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: tschwinge at gcc dot gnu.org
CC: jakub at gcc dot gnu.org
Target Milestone: ---
If a call to the acc_on_device function has a compile-time constant argument,
the function call evaluates to a compile-time constant value only for C and C++
but not for Fortran. "As far as I remember, the Fortran front end doesn't know
about/doesn't know how to use these GCC builtins"
(<http://mid.mail-archive.com/87zj28mve5.fsf@kepler.schwinge.homeip.net>).
