Additionally, there are still the 8 functions declared noreturn in
asan_report.cc that clang expects to "not return". These generate 16
warnings during the ALL_BUILD build and 8 more warnings during the check-all
build.

So, the symbols are colliding. Something is set up wrong in the xcode project.

Following a blend of instructions on 3 web pages, I have succeeded in getting
LLVM 3.2 (with clang, extras, and compiler-rt) building - but not testing - on
Xcode. I used CMake 2.8.10 GUI to create the Xcode project file. Below are my
notes.
First, I believe CMake ends up setting things up so that Xcode has 1 warning
after scanning the project having to do with hires images or some such… it takes
a long time to fix that up in a project as large as this, but I'm not sure
there's anything we can do about it.
Second, a build of the ALL_BUILD target in Xcode produces 16 warnings about 8
functions declared noreturn, but without a expected __builtin_unreachable()
before the end of the function. (The first attempt to build produced 2 errors,
the first an unable to create directory error for
runtime/libprofile/LLVM.build/Debug/profile_rt-static.build/Objects-normal/x86_64;
the second a libtool failure… both went away upon a rebuild.)
Third, a build of the check-all target produced 8 warnings about the 8 functions
declared noreturn as for ALL_BUILD, and 6 or 7 "errors", mostly from
asan_mac_test.mm<http://asan_mac_test.mm/>. After fixing up these
"errors" (int vs. size_t comparisons and malloc being assigned to
volatile pointers), I got 372 duplicate symbol errors from this:

Recently the way we build ASan unit tests has changed. Could you please check if
your XCode build works for the trunk?

TL;DR: the compiler is wrong here: the functions are in fact noreturn, because there is a local variable that has a noreturn destructor. this is already fixed in new Clang, but not in your host compiler.> > On Dec 21, 2012, at 12:13 AM, Alexey Samsonov <samsonov at google.com> > wrote: > > Hi Richard! > > On Thu, Dec 20, 2012 at 12:48 AM, Nick Kledzik <kledzik at apple.com> wrote: > >> Those look like the linker is being passed the same .o file built >> twice, ex: >> ../Objects-normal/x86_64/asan_globals_test.o >> ../lib/asan/tests/asan_globals_test.cc.asan.o >> >> So, the symbols are colliding.
