From: Thomas Schwinge <tschwinge@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc/devel/omp/gcc-12] Fix 'libgomp.{c-c++-common, fortran}/target-present-*' test cases Date: Wed, 15 Feb 2023 19:01:50 +0000 (GMT) [thread overview] Message-ID: <20230215190150.CED2E3858D28@sourceware.org> (raw) https://gcc.gnu.org/g:bbda035ee62ba4db21356136c97e9d83a97ba7d1 commit bbda035ee62ba4db21356136c97e9d83a97ba7d1 Author: Thomas Schwinge <thomas@codesourcery.com> Date: Wed Feb 15 12:39:19 2023 +0100 Fix 'libgomp.{c-c++-common,fortran}/target-present-*' test cases Their execution isn't expected to error out if we've been *compiling for any offload target*, but rather if they're *executing on a non-shared memory offload device*. For example, if (any) offloading is configured but not effective (no device available, for example), you'd get: PASS: libgomp.c/../libgomp.c-c++-common/target-present-1.c (test for excess errors) FAIL: libgomp.c/../libgomp.c-c++-common/target-present-1.c execution test PASS: libgomp.c/../libgomp.c-c++-common/target-present-2.c (test for excess errors) FAIL: libgomp.c/../libgomp.c-c++-common/target-present-2.c execution test PASS: libgomp.c/../libgomp.c-c++-common/target-present-3.c (test for excess errors) FAIL: libgomp.c/../libgomp.c-c++-common/target-present-3.c execution test PASS: libgomp.c++/../libgomp.c-c++-common/target-present-1.c (test for excess errors) FAIL: libgomp.c++/../libgomp.c-c++-common/target-present-1.c execution test PASS: libgomp.c++/../libgomp.c-c++-common/target-present-2.c (test for excess errors) FAIL: libgomp.c++/../libgomp.c-c++-common/target-present-2.c execution test PASS: libgomp.c++/../libgomp.c-c++-common/target-present-3.c (test for excess errors) FAIL: libgomp.c++/../libgomp.c-c++-common/target-present-3.c execution test PASS: libgomp.fortran/target-present-1.f90 -O0 (test for excess errors) FAIL: libgomp.fortran/target-present-1.f90 -O0 execution test [...] PASS: libgomp.fortran/target-present-2.f90 -O0 (test for excess errors) FAIL: libgomp.fortran/target-present-2.f90 -O0 execution test [...] PASS: libgomp.fortran/target-present-3.f90 -O0 (test for excess errors) FAIL: libgomp.fortran/target-present-3.f90 -O0 execution test [...] Also, verify reaching a checkpoint before the expected error condition -- and fix up one case where that didn't happen; missing OpenMP 'map' clauses ('libgomp.fortran/target-present-2.f90').
