Bug ID: 85166
Summary: [ntptx, libgfortran] Libgomp fortran tests using stop
in offloaded fns fail to compile
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: vries at gcc dot gnu.org
Target Milestone: ---
Atm for nvptx offloading we have lots of fortran tests (both openmp and
openacc) fail like this:
...
unresolved symbol _gfortran_stop_numeric
FAIL: libgomp.fortran/examples-4/async_target-2.f90 -O0 (test for excess
errors)
UNRESOLVED: libgomp.fortran/examples-4/async_target-2.f90 -O0 compilation
failed to produce executable
...
Recently "[libgomp testsuite] Replace non-standard call abort by STOP n" was
committed.
In libgfortran/Makefile.in we have:
...
@LIBGFOR_MINIMAL_FALSE@runtime/stop.c
...
so the function _gfortran_stop_numeric contained in stop.c doesn't get build
for LIBGFOR_MINIMAL.
The LIBGFOR_MINIMAL setting is only active for nvptx:
...
if test "x${target_cpu}" = xnvptx; then
LIBGFOR_MINIMAL_TRUE=
LIBGFOR_MINIMAL_FALSE='#'
else
LIBGFOR_MINIMAL_TRUE='#'
LIBGFOR_MINIMAL_FALSE=
fi
...
