* gimple.h (gimple_build_switch): Remove. (gimple_build_switch_vec): Promote to the new gimple_build_switch. (gimple_switch_default_label): Assert the default case label is really a default case label. (gimple_switch_set_default_label): Likewise. * gimple.c (gimple_build_switch_nlabels): Make sure a default label is passed in, and simplify accordingly. (gimple_build_switch): Removed. (gimple_build_switch_vec): Rename to gimple_build_switch. * gimplify.c (gimplify_switch_expr): Update gimple_build_switch use. * gimple-pretty-print.c (dump_gimple_switch): Do not accept a NULL case label. * stmt.c (expand_case): Simplify using the fact that every GIMPLE switch must have a default case. * tree-cfg.c (group_case_labels_stmt): Likewise. (verify_gimple_switch): Use gimple_switch_label in verifier to get the label at index 0, and verify that it is a valid default case. * except.c (sjlj_emit_dispatch_table): Rewrite construction of the switch for dispatching. * tree-eh.c (lower_try_finally_switch): Update gimple_build_switch use. (lower_eh_dispatch): Likewise. * tree-vrp.c (execute_vrp): Use gimple_switch_label to get the case label at index 0 before turning it into a default case label. * omp-low.c (expand_omp_sections): Update gimple_build_switch use. * tree-switch-conversion.c (emit_case_bit_tests): Get the default case label using gimple_switch_default_label. (collect_switch_conv_info): Likewise. (process_switch): Likewise. * doc/gimple.texi: Update documentation of gimple_build_switch. From-SVN: r190925
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.
