Numerous ObjC DejaGNU failures on i686-pc-linux-gnu

Numerous ObjC DejaGNU failures on i686-pc-linux-gnu

[Ziemowit Laski]

On i686-pc-linux-gnu, ObjC DejaGNU tests against mainline perform 
miserably:

                 === objc Summary ===

# of expected passes            466
# of unexpected failures        559
# of unresolved testcases       532
# of unsupported tests          21

Upon closer inspection, the vast majority of the failures are due to:

/home/zlaski/fsf/obj/HEAD/i686-pc-linux-gnu/./libobjc/.libs/libobjc.so: 
undefined reference to `objc_hash_string'
/home/zlaski/fsf/obj/HEAD/i686-pc-linux-gnu/./libobjc/.libs/libobjc.so: 
undefined reference to `objc_compare_strings'
/home/zlaski/fsf/obj/HEAD/i686-pc-linux-gnu/./libobjc/.libs/libobjc.so: 
undefined reference to `objc_compare_ptrs'
/home/zlaski/fsf/obj/HEAD/i686-pc-linux-gnu/./libobjc/.libs/libobjc.so: 
undefined reference to `objc_hash_ptr'
collect2: ld returned 1 exit status

The 4 symbols are all 'static inline' functions defined in objc/hash.h. 
  In the static archive, they appear in the modules in which they are 
used, e.g.,

zlaski@johada4:libobjc> nm 
/home/zlaski/fsf/obj/HEAD/i686-pc-linux-gnu/./libobjc/.libs/libobjc.a | 
egrep ':$|objc_hash_string'
archive.o:
0000316d t objc_hash_string
class.o:
encoding.o:
gc.o:
hash.o:
init.o:
linking.o:
misc.o:
nil_method.o:
NXConstStr.o:
Object.o:
objects.o:
Protocol.o:
sarray.o:
selector.o:
000000d1 t objc_hash_string
sendmsg.o:
thr.o:
thr-objc.o:
exception.o:
hash_compat.o:
00000109 t objc_hash_string

but the shared library winds up with undefined references, e.g.:

zlaski@johada4:libobjc> nm 
/home/zlaski/fsf/obj/HEAD/i686-pc-linux-gnu/./libobjc/.libs/libobjc.so 
| egrep ':$|objc_hash_string'
00011739 t objc_hash_string
          U objc_hash_string

Has anyone else seen this?  I'm trying to debug any ObjC failures 
caused by our (i.e., Apple's) recent ObjC/ObjC++ integration work...
I've upgraded to binutils-2.16, but that did not help things.

Thanks in advance for any suggestions,
