From b2202431910e30d8505c94d1cb9341cac7080d10 Mon Sep 17 00:00:00 2001 From: Jakub Jelinek Date: Wed, 20 Apr 2022 19:06:17 +0200 Subject: [PATCH] fortran: Fix up gfc_trans_oacc_construct [PR104717] So that move_sese_region_to_fn works properly, OpenMP/OpenACC constructs for which that function is invoked need an extra artificial BIND_EXPR around their body so that we move all variables of the bodies. The C/C++ FEs do that both for OpenMP constructs like OMP_PARALLEL, OMP_TASK or OMP_TARGET and for OpenACC constructs that behave similarly to OMP_TARGET, but the Fortran FE only does that for OpenMP constructs. The following patch does that for OpenACC constructs too.
