[release_34] [compiler-rt] UBSAN vptr.cpp test failure

Clang Frontend
#1

Hi,

In release_34 branch I got the following test failure on i586 Linux. Can someone shed some light into this? This is the last regression compared to 3.3 release.

******************** TEST ‘UndefinedBehaviorSanitizer-Standalone :: TypeCheck/vptr.cpp’ FAILED ********************

#2

Looks like a typo in the pattern used to accomodate 32bit. I'll fix
this shortly, once laptop chugs through building trunk :).

That said, it seems compiler-rt doesn't get much attention on 32bit.
Would it be possible to add compiler-rt to one of the existing 32bit builders?

Ideally we'd catch this sort of thing long before release testing... :slight_smile:

Committed as r196799.

CC'ing Bill to add to your previous request to cherry-pick r196612
onto the 3.4 release.

@Bill: These are low-risk changes that fix tests on 32bit platforms,
and are important to at least one linux distribution's packaging
process.
