When the GCC build runs GCC_FOR_TARGET, e.g. for selftests or for dumping specs, it doesn't use TFLAGS in non-bootstrap scenarios. This patch arranges for TFLAGS to be passed from the top level down to gcc in GCC_FOR_TARGET in this case. Another issue related with TFLAGS fixed herein is that there's no easy way to add a TFLAGS to GCC_FOR_TARGET when running "make gnatlib" within the gcc directory. Overriding all of GCC_FOR_TARGET is somewhat cumbersome, so I'm adding TFLAGS support to gcc/Makefile.in, getting it added to GCC_FOR_TARGET, as it would when passed down from the top level. for ChangeLog * Makefile.tpl (HOST_EXPORTS): Add TFLAGS to GCC_FOR_TARGET. (EXTRA_GCC_FLAGS): Likewise. * Makefile.in: Rebuilt. for gcc/ChangeLog * Makefile.in (TFLAGS): New. (GCC_FOR_TARGET): Add TFLAGS. (FLAGS_TO_PASS): Pass TFLAGS down.
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.
