This patch uses the new ISA data structure to determine which builtins to add. It entirely eliminates the need for insn_flags to be a global variable, but we're about to delete that in the following patches, so for now we leave it as a global. * arm-builtins.c: Include sbitmap.h. (def_mbuiltin): Change first parameter to a flag bit. Use it to test available features in the current target. (struct builtin_description): Change type of feature field. (IWMMXT_BUILTIN): Use the isa_features types. (IWMMXT2_BUILTIN): Likewise. (IWMMXT_BUILTIN2): Likewise. (IWMMXT2_BUILTIN2): Likewise. (CRC32_BUILTIN): Likewise. (CRYPTO_BUILTIN): Likewise. (iwmmx_builtin): Likewise. (iwmmx2_builtin): Likewise. (arm_iwmmxt_builtin): Check for specific feature bits. From-SVN: r243702
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.
