The TYPE_ALIGN_OK flag had originally been a GCC flag tested in the RTL expander and was at some point kicked out of the middle-end to become a pure Gigi flag. But it's only set for tagged types and CW-equivalent types and can be replaced by a explicit predicate without too much work. gcc/ada/ChangeLog: * gcc-interface/ada-tree.h (TYPE_ALIGN_OK): Delete. * gcc-interface/decl.cc (gnat_to_gnu_entity): Do not set it. * gcc-interface/gigi.h (standard_datatypes): Add ADT_tag_name_id. (tag_name_id): New macro. (type_is_tagged_or_cw_equivalent): New inline predicate. * gcc-interface/trans.cc (gigi): Initialize tag_name_id. (gnat_to_gnu) <N_Unchecked_Type_Conversion>: Replace tests on TYPE_ALIGN_OK with calls to type_is_tagged_or_cw_equivalent. (addressable_p): Likewise. * gcc-interface/utils.cc (convert): Likewise. * gcc-interface/utils2.cc (build_binary_op): Likewise.
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
