[llvm-dev] sanitizer test case failures after OS update

I updated one of my powerpc64le llvm test systems to Fedora 25 and I 
started getting a whole bunch of sanitizer test case failures.  I tried 
testing some earlier revisions on the new OS that had worked fine under 
the old but they generate the same errors now so it isn't any changes in 
llvm.

There are two different errors:

FATAL: ThreadSanitizer: unsupported VMA range
FATAL: Found 47 - Supported 44 and 46

and

FATAL: Code 0x00010eddf660 is out of application range. Non-PIE build?
FATAL: MemorySanitizer can not mmap the shadow memory.
FATAL: Make sure to compile with -fPIE and to link with -pie.
FATAL: Disabling ASLR is known to cause this error.
FATAL: If running under GDB, try 'set disable-randomization off'.

Obviously something changed when I updated the OS but I am not sure how 
to fix it.  The compilation options didn't change and ASLR isn't 
disabled.  I used the same gcc compiler to build llvm under the 
different OS releases.

The first full test after the OS update is here: 
http://lab.llvm.org:8011/builders/sanitizer-ppc64le-linux/builds/3636

Any ideas?  Thanks!


Here's the full output from one of the failures:

[llvm-dev] sanitizer test case failures after OS update

Hi Bill:

Not sure if it was intentional, but the old builds set CC, CXX, and
LD_LIBRARY_PATH explicitly, but the new ones don't.  Also, you seem to be
linking against gcc 7.2 libs above, but building with gcc 6.4.1.

hth...

[llvm-dev] sanitizer test case failures after OS update

I tried some runs using different versions of gcc and the one I posted 
was from when I used gcc 7.2.  The actual bot was using the system gcc 
6.4.1 compiler and libraries and got the same sorts of failures:

[llvm-dev] sanitizer test case failures after OS update

This looks to be due to the new kernel using 47 bits for addressing
and the ppc specific ASAN code is only setup to handle 44 or 46.
Talking with Steve Munroe, he says there is some work (already done?)
to handle 48 and 49 bits as well.  We'll need a change ASAN to
handle those extra bits.  It would be nice if we could just detect
what the value is and use that, rather than having fixed specific
values we know about and handle.

Oops, I meant TSAN above, although ASAN has similar code and
restrictions IIRC.
