All,
this patch adds support for asan for i?86/x86_64-*freebsd*.
Test results can be found on the list.
These modifications belong only to gcc. There is one modification to
asan/asan_linux.cc, this one is sent upstream. Until this one is in, my
patch is on hold.
One thing to note, FreeBSD does not need to link against -ldl. That is
why I added an extra config check.
But nevertheless I'd like to get some comments on the patch.
Thanks to Jakub and Dan McGregor.
Thanks,
Andreas

* config/i386/i386.h: Define two new macros:
SUBTARGET_SHADOW_OFFSET_64 and SUBTARGET_SHADOW_OFFSET_32.
* config/i386/i386.c (ix86_asan_shadow_offset): Use these macros.
* config/i386/darwin.h: Override the SUBTARGET_SHADOW_OFFSET_64
macro.
* config/i386/freebsd.h: Override the SUBTARGET_SHADOW_OFFSET_64
and the SUBTARGET_SHADOW_OFFSET_32 macro.
* config/freebsd.h (LIBASAN_EARLY_SPEC): Define.
(LIBTSAN_EARLY_SPEC): Likewise.
(LIBLSAN_EARLY_SPEC): Likewise.

* configure.ac: Replace the hard-coded -ldl requirement for
link_sanitizer_common with a configure time check for -ldl.
* configure: Regenerate.
* configure.tgt: Add x86_64- and i?86-*-freebsd* targets.
The configury bits are fine. Uros would own review on the x86 specific
changes.
