re PR middle-end/66133 (Wrong-code with noreturn #pragma omp task body)
PR middle-end/66133
* omp-low.c (expand_omp_taskreg): For GIMPLE_OMP_TASK expansion,
make sure it is never noreturn, even when the task body does not
return.
(lower_omp_taskreg): For GIMPLE_OMP_TASK, emit GIMPLE_OMP_CONTINUE
right before GIMPLE_OMP_RETURN.
(make_gimple_omp_edges): Accept GIMPLE_OMP_CONTINUE as ->cont
for GIMPLE_OMP_TASK. For GIMPLE_OMP_RETURN corresponding to
GIMPLE_OMP_TASK add an EDGE_ABNORMAL edge from entry to exit.
* testsuite/libgomp.c/pr66133.c: New test.
