This patch adds the ability to configure GCC on AIX to build as a 64 bit application and to build target libraries "FAT" libraries in both 32 bit and 64 bit mode. The patch adds makefile fragment hooks to target libraries that allows them to include target-specific rules. The target specific rules for AIX place both 32 bit and 64 bit objects and shared objects in archives at the top-level, not multilib subdirectories. The multilibs are built in subdirectories, but must be combined during the last parts of the target library build process. Because of the way that GCC bootstrap works, the libraries must be combined during the multiple stages of GCC bootstrap, not solely when installed in the final destination, so the libraries are correct at the end of each target library build stage, not solely an install recipe. gcc/ChangeLog 2020-06-21 David Edelsohn <dje.gcc@gmail.com> * config.gcc: Use t-aix64, biarch64 and default64 for cpu_is_64bit. * config/rs6000/aix72.h (ASM_SPEC): Remove aix64 option.

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.
