GCC modified for the FreeChainXenon project
dfe06d3e7f
This patch defines a new asan_shadow_offset target macro, instead of having a mere macro in the asan.c file. It becomes thus cleaner to define the target macro for targets that supports asan, namely x86 for now. The ASAN_SHADOW_SHIFT (which, along with the asan_shadow_offset constant, is used to compute the address of the shadow memory byte for a given memory address) is defined in asan.h. gcc/ChangeLog * toplev.c (process_options): Warn and turn off -faddress-sanitizer if not supported by target. * asan.c: Include target.h. (asan_scale, asan_offset_log_32, asan_offset_log_64, asan_offset_log): Removed. (build_check_stmt): Use ASAN_SHADOW_SHIFT and targetm.asan_shadow_offset (). (asan_instrument): Don't initialize asan_offset_log. * asan.h (ASAN_SHADOW_SHIFT): Define. * target.def (TARGET_ASAN_SHADOW_OFFSET): New hook. * doc/tm.texi.in (TARGET_ASAN_SHADOW_OFFSET): Add it. * doc/tm.texi: Regenerated. * Makefile.in (asan.o): Depend on $(TARGET_H). * config/i386/i386.c (ix86_asan_shadow_offset): New function. (TARGET_ASAN_SHADOW_OFFSET): Define. From-SVN: r193433 |

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.
