Instrument built-in memory access function calls
This patch instruments many memory access patterns through builtins.
Basically, for a call like:
__builtin_memset (from, 0, n_bytes);
the patch would only instrument the accesses at the beginning and at
the end of the memory region [from, from + n_bytes]. This is the
strategy used by the llvm implementation of asan.
This instrumentation is done for all the memory access builtin
functions that expose a well specified memory region -- one that
explicitly states the number of bytes accessed in the region.
A special treatment is used for __builtin_strlen. The patch
instruments the access to the first byte of its argument, as well as
the access to the byte (of the argument) at the offset returned by
strlen.
For the __sync_* and __atomic* calls the patch instruments the access
to the bytes pointed to by the argument.
While doing this, I have added a new parameter to build_check_stmt to
decide whether to insert the instrumentation code before or after the
statement iterator. This allows us to do away with the
gsi_{next,prev} dance we were doing in the callers of this function.
Tested by running cc1 -fasan on variations of simple programs like:
int
foo ()
{
char foo[10] = {0};
foo[0] = 't';
foo[1] = 'e';
foo[2] = 's';
foo[3] = 't';
int l = __builtin_strlen (foo);
int n = sizeof (foo);
__builtin_memset (&foo[4], 0, n - 4);
__sync_fetch_and_add (&foo[11], 1);
return l;
}
and by starring at the gimple output which for this function is:

Initial asan cleanups
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.

Initial import of asan from the Google branch
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.
