I'm trying to add a define_subst use in the arm backend but am getting many build errors complaining about: `set_attr_alternative' is unsupported by `define_subst' Looking at the gensupport.c code it iterates over all define_insns and errors if any of them have set_attr_alternative. The usecase I'm targetting doesn't involve patterns with set_attr_alternative, so I would like to make the define_subst handling more robust to only error out if the define_subst is actually attempted on a set_attr_alternative. This patch produces the error only if the set_attr_alternative attr matches the subst name. This allows a build of the arm backend with a define_subst usage to succeed. PR other/91255 * gensupport.c (has_subst_attribute): Error out on set_attr_alternative only if subst_name matches curr_attr string. From-SVN: r274564 |

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.
