From 178ac530fe67e4f2fc439cc4ce89bc19d571ca31 Mon Sep 17 00:00:00 2001 From: Tobias Burnus Date: Mon, 24 Oct 2022 15:19:00 +0200 Subject: OpenMP: Fix reverse offload GOMP_TARGET_REV IFN corner cases [PR107236] For 'target parallel' and similarly nested directives, cgraph_node's calls_declare_variant_alt was not set in the parent region node but in cfun->decl. Hence, pass_omp_device_lower did not process handle the internal function GOMP_TARGET_REV. - Solution is to set it to the DECL_CONTEXT, which is set in adjust_context_and_scope. The cgraph_node::create_clone issue is exposed with -O2 for the existing libgomp.fortran/reverse-offload-1.f90. PR middle-end/107236 gcc/ChangeLog: * omp-expand.cc (expand_omp_target): Set calls_declare_variant_alt in DECL_CONTEXT and not to cfun->decl. * cgraphclones.cc (cgraph_node::create_clone): Copy also the node's calls_declare_variant_alt value. gcc/testsuite/ChangeLog: * gfortran.dg/gomp/target-device-ancestor-6.f90: New test. --- gcc/cgraphclones.cc | 1 + 1 file changed, 1 insertion(+) (limited to 'gcc/cgraphclones.cc') diff --git a/gcc/cgraphclones.cc b/gcc/cgraphclones.cc index eb0fa87..bb4b3c5 100644 --- a/gcc/cgraphclones.cc +++ b/gcc/cgraphclones.cc @@ -375,6 +375,7 @@ cgraph_node::create_clone (tree new_decl, profile_count prof_count, if (!new_inlined_to) prof_count = count.combine_with_ipa_count (prof_count); new_node->count = prof_count; + new_node->calls_declare_variant_alt = this->calls_declare_variant_alt; /* Update IPA profile.
