From: Thomas Schwinge <tschwinge@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc/devel/omp/gcc-12] Add 'libgomp.oacc-fortran/declare-allocatable-1-runtime.f90' Date: Wed, 2 Nov 2022 21:07:36 +0000 (GMT) [thread overview] Message-ID: <20221102210736.468493857402@sourceware.org> (raw) https://gcc.gnu.org/g:63918a81a59349280f2e67324782c186cade0822 commit 63918a81a59349280f2e67324782c186cade0822 Author: Thomas Schwinge <thomas@codesourcery.com> Date: Fri Oct 14 17:36:51 2022 +0200 Add 'libgomp.oacc-fortran/declare-allocatable-1-runtime.f90' ... which is 'libgomp.oacc-fortran/declare-allocatable-1.f90' adjusted for missing support for OpenACC "Changes from Version 2.0 to 2.5": "The 'declare create' directive with a Fortran 'allocatable' has new behavior". Thus, after 'allocate'/before 'deallocate', call 'acc_create'/'acc_delete' manually. libgomp/ * testsuite/libgomp.oacc-fortran/declare-allocatable-1-runtime.f90: New.
