* gensupport.c: Include hashtab.h. (insn_elision, condition_table, hash_c_test, cmp_c_test, maybe_eval_c_test): New routines and data structures to support insn elision. (init_md_reader): Read and initialize the condition_table. (read_md_rtx): Discard insn patterns whose C test is provably always false. * gensupport.h: Declare new functions and data structures. * genconditions.c, dummy-conditions.c: New files. * Makefile.in: Build genconditions; run it to construct insn-conditions.c; build that and link it into most gen* programs. (HOST_SUPPORT, HOST_EARLY_SUPPORT): New variables. (GEN): Delete, unused. (STAGESTUFF): Update. * gencodes.c: (gen_insn): #define CODE_FOR_xxx equal to CODE_FOR_nothing for all elided patterns. (main): Tweaked to support this. * genflags.c (gen_proto): Emit a static inline generator function here for all elided patterns, which simply returns NULL_RTX. (gen_insn): Do not define HAVE_xxx for elided patterns. (main): Tweaked to support this. No need to forward-declare struct rtx_def. * genrecog.c: Do not bother emitting the C test if it's known to be true at compile time. From-SVN: r55839 |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file 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.html for how to report bugs usefully.
