--- Comment #13 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Iain Buclaw <ibuc...@gcc.gnu.org>: https://gcc.gnu.org/g:8a9ce39f8bbb2ae0798bec0ed2051a5f10b21122 commit r10-7793-g8a9ce39f8bbb2ae0798bec0ed2051a5f10b21122 Author: Iain Buclaw <ibuc...@gdcproject.org> Date: Sun Apr 19 09:54:25 2020 +0200 d: Fix FAIL in gdc.dg/runnable.d on X32 targets (PR94609) Patch fixes test failure seen on X32 where a nested struct was passed in registers, rather than via invisible reference. Now, all non-POD structs are passed by invisible reference, not just those with a user-defined copy constructor/destructor. gcc/d/ChangeLog: PR d/94609 * d-codegen.cc (argument_reference_p): Don't check TREE_ADDRESSABLE. (type_passed_as): Build reference type if TREE_ADDRESSABLE. * d-convert.cc (convert_for_argument): Build explicit TARGET_EXPR if needed for arguments passed by invisible reference. * types.cc (TypeVisitor::visit (TypeStruct *)): Mark all structs that are not POD as TREE_ADDRESSABLE.
