This patch makes it a compile-time error for an internal-fn optab to FAIL. There are certainly other optabs and patterns besides these that aren't allowed to fail, but this at least deals with the immediate point of controversy. Tested normally on x86_64-linux-gnu. Also tested by building one configuration per cpu directory. arc-elf and pdp11 didn't build for unrelated reasons, but I checked that insn-emit.o built for both without error. gcc/ * Makefile.in (GENSUPPORT_H): New macro. (build/gensupport.o, build/read-rtl.o, build/genattr.o) (build/genattr-common.o, build/genattrtab.o, build/genautomata.o) (build/gencodes.o, build/genconditions.o, build/genconfig.o) (build/genconstants.o, build/genextract.o, build/genflags.o) (build/gentarget-def.o): Use it. (build/genemit.o): Likewise. Depend on internal-fn.def. * genopinit.c: Move block comment to optabs.def. (optab_tag, optab_def): Move to gensupport.h (pattern): Likewise, renaming to optab_pattern. (match_pattern): Move to gensupport.c (gen_insn): Use find_optab. (patterns, pattern_cmp): Replace pattern with optab_pattern. (main): Likewise. Use num_optabs. * optabs.def: Add comment that was previously in genopinit.c. * gensupport.h (optab_tag): Moved from genopinit.c (optab_def): Likewise, expanding commentary. (optab_pattern): Likewise, after renaming from pattern. (optabs, num_optabs, find_optab): Declare. * gensupport.c (optabs): Moved from genopinit.c. (num_optabs): New variable. (match_pattern): Moved from genopinit.c. (find_optab): New function, extracted from genopinit.c:gen_insn. * genemit.c (nofail_optabs): New variable. (emit_c_code): New function. (gen_expand): Check whether the instruction is an optab that isn't allowed to fail. Call emit_c_code. (gen_split): Call emit_c_code here too. (main): Initialize nofail_optabs. Don't emit FAIL and DONE here. From-SVN: r231160 |

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.
