The reason\nfor that is that a former global VAR_DECL is being replaced through\nDECL_VALUE_EXPR with a target mapping thereof and so is considered as\npotentially trapping. Fixed by pre-gimplifying the operand. \nBootstrapped/regtested on x86_64-linux and i686-linux, committed so far to\ntrunk.\n\n2017-09-05 Jakub Jelinek <jakub@redhat.com>\n\n\tPR middle-end/81768\n\t* omp-expand.c (expand_omp_simd): Force second operands of COND_EXPR\n\tinto gimple val before gimplification fo the COND_EXPR.\n\n\t* gcc.dg/gomp/pr81768-1.c: New test.\n\n\n\tJakub", "diff": "--- gcc/omp-expand.c.jj\t2017-09-01 09:26:27.000000000 +0200\n+++ gcc/omp-expand.c\t2017-09-05 13:13:49.303159003 +0200\n@@ -4730,24 +4730,28 @@ expand_omp_simd (struct omp_region *regi\n \t tree itype2 = TREE_TYPE (fd->loops[i - 1].v);\n \t if (POINTER_TYPE_P (itype2))\n \t\titype2 = signed_type_for (itype2);\n+\t t = fold_convert (itype2, fd->loops[i - 1].step);\n+\t t = force_gimple_operand_gsi (&gsi, t, true, NULL_TREE, true,\n+\t\t\t\t\t GSI_SAME_STMT);\n \t t = build3 (COND_EXPR, itype2,\n \t\t\t build2 (fd->loops[i].cond_code, boolean_type_node,\n \t\t\t\t fd->loops[i].v,\n \t\t\t\t fold_convert (itype, fd->loops[i].n2)),\n-\t\t\t build_int_cst (itype2, 0),\n-\t\t\t fold_convert (itype2, fd->loops[i - 1].step));\n+\t\t\t build_int_cst (itype2, 0), t);\n \t if (POINTER_TYPE_P (TREE_TYPE (fd->loops[i - 1].v)))\n \t\tt = fold_build_pointer_plus (fd->loops[i - 1].v, t);\n \t else\n \t\tt = fold_build2 (PLUS_EXPR, itype2, fd->loops[i - 1].v, t);\n \t expand_omp_build_assign (&gsi, fd->loops[i - 1].v, t);\n \n+\t t = fold_convert (itype, fd->loops[i].n1);\n+\t t = force_gimple_operand_gsi (&gsi, t, true, NULL_TREE, true,\n+\t\t\t\t\t GSI_SAME_STMT);\n \t t = build3 (COND_EXPR, itype,\n \t\t\t build2 (fd->loops[i].cond_code, boolean_type_node,\n \t\t\t\t fd->loops[i].v,\n \t\t\t\t fold_convert (itype, fd->loops[i].n2)),\n-\t\t\t fd->loops[i].v,\n-\t\t\t fold_convert (itype, fd->loops[i].n1));\n+\t\t\t fd->loops[i].v, t);\n \t expand_omp_build_assign (&gsi, fd->loops[i].v, t);\n \t }\n \t}\n--- gcc/testsuite/gcc.dg/gomp/pr81768-1.c.jj\t2017-09-05 13:59:57.821977911 +0200\n+++ gcc/testsuite/gcc.dg/gomp/pr81768-1.c\t2017-09-05 13:50:24.000000000 +0200\n@@ -0,0 +1,15 @@\n+/* PR middle-end/81768 */\n+/* { dg-do compile } */\n+\n+float b[10][15][10];\n+\n+void\n+foo (void)\n+{\n+ float *i;\n+#pragma omp target parallel for simd schedule(static, 32) collapse(3)\n+ for (i = &b[0][0][0]; i < &b[0][0][10]; i++)\n+ for (float *j = &b[0][15][0]; j > &b[0][0][0]; j -= 10)\n+ for (float *k = &b[0][0][10]; k > &b[0][0][0]; --k)\n+\tb[i - &b[0][0][0]][(j - &b[0][0][0]) / 10 - 1][(k - &b[0][0][0]) - 1] -= 3.5;\n+}\n", "prefixes": [ "committed" ] }
