GCC modified for the FreeChainXenon project
cba079f354
This patch moves the definitions for DO_STMT, FOR_STMT, WHILE_STMT, SWITCH_STMT, BREAK_STMT, and CONTINUE_STMT from the C++ front end to c-family. This includes the genericizers, pretty-printers, and dump support as well as the tree definitions and accessors. Some related code for OMP_FOR and similar OMP constructs is also moved. 2020-08-12 Sandra Loosemore <sandra@codesourcery.com> gcc/c-family/ * c-common.c (c_block_may_fallthrough): New, split from cxx_block_may_fallthrough in the cp front end.

(get_bc_label, expr_loc_or_loc): Move from cp front end. (genericize_c_loop): Move from cp front end. (genericize_for_stmt, genericize_while_stmt): Likewise. (genericize_do_stmt, genericize_switch_stmt): Likewise. (genericize_continue_stmt, genericize_break_stmt): Likewise. (genericize_omp_for_stmt): Likewise. (c_genericize_control_stmt): New function using code split from cp front end. (c_genericize_control_r): New. (c_genericize): Call walk_tree with c_genericize_control_r. * c-pretty-print.c (c_pretty_printer::statement): Move code to handle structured loop and switch tree nodes here from cp front end. gcc/cp/ * cp-gimplify.c (enum bc_t, bc_label): Move to c-family. (begin_bc_block, finish_bc_block, get_bc_label): Likewise. (genericize_cp_loop): Likewise. (genericize_for_stmt, genericize_while_stmt): Likewise. (genericize_do_stmt, genericize_switch_stmt): Likewise. (genericize_continue_stmt, genericize_break_stmt): Likewise. (genericize_omp_for_stmt): Likewise. (cp_genericize_r): Call c_genericize_control_stmt instead of above functions directly. (cp_genericize): Call save_bc_state and restore_bc_state instead of manipulating bc_label directly. * cp-objcp-common.c (cxx_block_may_fallthru): Defer to c_block_may_fallthru instead of handling SWITCH_STMT here. (cp_common_init_ts): Move handling of loop and switch-related statements to c-family. * cp-tree.def (FOR_STMT, WHILE_STMT, DO_STMT): Move to c-family. (BREAK_STMT, CONTINUE_STMT, SWITCH_STMT): Likewise. * cp-tree.h (LABEL_DECL_BREAK, LABEL_DECL_CONTINUE): Likewise. (WHILE_COND, WHILE_BODY): Likewise. (DO_COND, DO_BODY): Likewise.

(Statements for C and C++): Rename node to reflect what the introduction already says about sharing between C and C++ front ends. Copy-edit and correct documentation for structured loops and switch. |

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.
