Currently if the user does not specify a default CPU or architecture the compiler provieds no default values in the spec defaults. We can try to work from TARGET_CPU_DEFAULT but pulling that into the driver is a bit crufty and doesn't really work well with the general spec-processing model. A better way is to ensure that with_cpu is always set appropirately during configure. To avoid problems with the multilib fragment processing we defer this until after we have processed any required fragments before selecting the default. * config.gcc (arm*-*-*): Ensure both target_cpu_cname and with_cpu are set after handling multilib fragments. Set target_cpu_default2 from with_cpu. From-SVN: r249291
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.
