[Bug target/44163] New: [4.6 Regression] Multiple failures in the objc and libgomp test suites

[dominiq at lps dot ens dot fr]

Since revision 159443, there are multiple failures in the objc and libgomp test
suites (see http://gcc.gnu.org/ml/gcc-testresults/2010-05/msg01478.html ). They
are all of the form:

/var/tmp//ccIspVYP.s:816:non-relocatable subtraction expression,
"___emutls_v.baz.1169" minus "L00000000002$pb"^M
/var/tmp//ccIspVYP.s:816:symbol: "___emutls_v.baz.1169" can't be undefined in a
subtraction expression^M

Reverting revision 159371 fixes these failures. This is probably related to
pr44146.

@159462 on powerpc64 with:

http://gcc.gnu.org/ml/gcc-patches/2010-05/msg01119.html
(and needed for m32, but not to solve the tls problem)
http://gcc.gnu.org/ml/gcc-patches/2010-05/msg01125.html

ObjC/C++ tls fails are limited to LTO-related

                === libgomp Summary ===

# of expected passes            4980
# of unsupported tests          4

still working on better ways to solve the TLS issues (monitor
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44132 for that)

I had to revert revision 159371 at revision 159429 with the patch
inhttp://gcc.gnu.org/ml/gcc-patches/2010-04/msg00129.html .

You had to revert 159371 in addition to the patch:
http://gcc.gnu.org/ml/gcc-patches/2010-05/msg01119.html

or instead of that patch?

Sorry for the confusion. 

In my powerpc-apple-darwin9 tree I have the patch in
http://gcc.gnu.org/ml/gcc-patches/2010-05/msg01119.html for a quite long time
(and I guess it is not applied in the "native" tree of regress). With revision
159371, I see the same failures as regress. These failures disappear if I
revert revision 159371 without any other change in my tree.

OK, might be worth double-checking - both parts are needed.

nope. that's just trunk.

I have clean libgomp results and only LTO FE fails,  on powerpc-apple-darwin9
@159476 
with http://gcc.gnu.org/ml/gcc-patches/2010-05/msg01119.html but...
*without* changing varpool.c.

@r160568 (or earlier) this is no longer showing.
