2012-11-12Initial asan cleanupsJakub Jelinek2-0/+8
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.

2012-11-12Initial import of asan from the Google branchWei Mi1-3/+10
This patch imports the initial state of asan as it was in the Google branch. It provides basic infrastructure for asan to instrument memory accesses on the heap, at -O3. Note that it supports neither stack nor global variable protection. The rest of the patches of the set is intended to further improve this base. gcc/ChangeLog * Makefile.in: Add asan.c and its dependencies. * common.opt: Add -faddress-sanitizer option. * invoke.texi: Document the new flag. * passes.c: Add the asan pass. * toplev.c (compile_file): Call asan_finish_file. * asan.c: New file. * asan.h: New file. * tree-pass.h: Declare pass_asan.
