GCC modified for the FreeChainXenon project

Hi all, This change refactors all the mbranch-protection option parsing code and types to make it common to both AArch32 and AArch64 backends. This change also pulls in some supporting types from AArch64 to make it common (aarch_parse_opt_result). The significant changes in this patch are the movement of all branch protection parsing routines from aarch64.c to aarch-common.c and supporting data types and static data structures. This patch also pre-declares variables and types required in the aarch32 back-end for moved variables for function sign scope and key to prepare for the impending series of patches that support parsing the feature mbranch-protection in the aarch32 back-end. gcc/ChangeLog: * common/config/aarch64/aarch64-common.cc: Include aarch-common.h. (all_architectures): Fix comment. (aarch64_parse_extension): Rename return type, enum value names. * config/aarch64/aarch64-c.cc (aarch64_update_cpp_builtins): Rename factored out aarch_ra_sign_scope and aarch_ra_sign_key variables. Also rename corresponding enum values. * config/aarch64/aarch64-opts.h (aarch64_function_type): Factor out aarch64_function_type and move it to common code as aarch_function_type in aarch-common.h. * config/aarch64/aarch64-protos.h: Include common types header, move out types aarch64_parse_opt_result and aarch64_key_type to aarch-common.h * config/aarch64/aarch64.cc: Move mbranch-protection parsing types and functions out into aarch-common.h and aarch-common.cc. Fix up all the name changes resulting from the move. * config/aarch64/aarch64.md: Fix up aarch64_ra_sign_key type name change and enum value. * config/aarch64/aarch64.opt: Include aarch-common.h to import type move. Fix up name changes from factoring out common code and data. * config/arm/aarch-common-protos.h: Export factored out routines to both backends. * config/arm/aarch-common.cc: Include newly factored out types. Move all mbranch-protection code and data structures from aarch64.cc. * config/arm/aarch-common.h: New header that declares types shared between aarch32 and aarch64 backends. * config/arm/arm-protos.h: Declare types and variables that are made common to aarch64 and aarch32 backends - aarch_ra_sign_key, aarch_ra_sign_scope and aarch_enable_bti. * config/arm/arm.opt (config/arm/aarch-common.h): Include header. (aarch_ra_sign_scope, aarch_enable_bti): Declare variable. * config/arm/arm.cc: Add missing includes. Co-Authored-By: Tejas Belagod <tbelagod@arm.com> |

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.
