Ignore Comment 1. The actual failures produce no particular error messages and
can't be reproduced by hand for the c-c++-common/asan/global-overflow-1.c -O1

The g++.dg/asan/interception-test-1.C test should have...
// { dg-skip-if "" { { *-*-darwin* } { "*" } { "" } }
since darwin uses mac function interposition rather than interception.

The c-c++-common/asan/swapcontext-test-1.c test case should have...
// { dg-skip-if "" { *-*-darwin* } { "*" } { "" } }
since ucontext support was depreciated in Mac OS X 10.6 and removed entirely in
Mac OS X 10.7.

c-c++-common/asan/global-overflow-1.c and c-c++-common/asan/stack-overflow-1.c
fail at -O1 and above because the out of bound read is not detected. If I
compile the tests with '-O1 -fno-tree-fre' or '-Ox -fno-tree-fre -fno-tree-pre'
(with x==2 or above), I get the expected output. Is this a bug in tree-fre/pre
or should these options be passed to the test?

Perhaps this is a red-herring, but comparing the assembly files for
stack-overflow-1.s and global-overflow-1.s generated on darwin and linux, I
notice that the linux assembly always has at least one instance of
__asan_report_load1 whereas only the assembly for -O0 on darwin shows a call to
___asan_report_load1. At the higher optimizations that fail to detect the out
of bound read, these calls to ___asan_report_load1 are missing.

Concerning the failure of c-c++-common/asan/rlimit-mmap-test-1.c, I have looked
at the man for setrlimit. For Linux I see:
RLIMIT_AS
...
RLIMIT_CORE
...
RLIMIT_CPU
...
RLIMIT_DATA
...
RLIMIT_FSIZE
...
RLIMIT_LOCKS (Early Linux 2.4 only)
...
RLIMIT_MEMLOCK
...
RLIMIT_MSGQUEUE (Since Linux 2.6.8)
...
RLIMIT_NICE (since Linux 2.6.12, but see BUGS below)
...
RLIMIT_NOFILE
...
RLIMIT_NPROC
...
RLIMIT_RSS
...
RLIMIT_RTPRIO (Since Linux 2.6.12, but see BUGS)
...
RLIMIT_RTTIME (Since Linux 2.6.25)
...
RLIMIT_SIGPENDING (Since Linux 2.6.8)
...
RLIMIT_STACK
...
But for darwin I only see:
RLIMIT_CORE
...
RLIMIT_CPU

RLIMIT_DATA
...
RLIMIT_FSIZE

RLIMIT_MEMLOCK

RLIMIT_NOFILE

The absence of RLIMIT_AS support on darwin appears to be a longstanding
issue...
http://lists.apple.com/archives/Unix-porting/2007/Apr/msg00026.html
and really should be fixed since SUSv3 Unix (which darwin claims to be) demands
it.

(In reply to comments #12 and #13)
With -O1, the invalid tests c-c++-common/asan/global-overflow-1.c and
c-c++-common/asan/stack-overflow-1.c are optimized to a valid "return 0" as
shown by the following differences between the outputs of -dump-tree-optimized
with and without -fno-tree-fre:
--- stack-overflow-1.c.164t.optimized 2012-12-16 17:26:13.000000000 +0100
+++ stack-overflow-1.c.164t_f.optimized 2012-12-16 17:25:13.000000000 +0100
@@ -3,18 +3,14 @@
main ()
{
- int res;
char x[10];
int ten.1;
- char _4;
<bb 2>:
__builtin_memset (&x, 0, 10);
ten.1_3 ={v} ten;
- _4 = x[ten.1_3];
- res_5 = (int) _4;
x ={v} {CLOBBER};
- return res_5;
+ return 0;
}
So the problem for these two tests has nothing to do with asan. Note that they
regress cleanly if I add '-fno-tree-fre -fno-tree-pre' to '-fno-builtin-memset'
in the dg-options. The optimization is also defeated If I add a line such as
x[1] = 1;
Although I doubt this behavior is a bug, I'll open a new PR for it tomorrow
unless there is some objection.

I have investigated the behavior of get/setrlimit(RLIMIT_AS...):
(1) looking at sys/resource.h it appears that RLIMIT_AS is an (undocumented)
alias of RLIMIT_RSS.
(2) RLIMIT_AS seems to be correctly gotten/set by get/setrlimit.
(3) However this does seems to affect the behavior of malloc.
The following patch fixes the failure

I am puzzled as to why this issue with global-overflow-1.c and
stack-overflow-1.c can't be triggered on x86_64 linux. The obvious change of
-mtune=core2 seems to be insufficient to cause the failures.

I have opened pr56053 for these failures. This PR could probably be closed as
