New Revision: 157822

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=157822

        * tree-profile.c (tree_init_ic_make_global_vars): Make static
        variables TLS.

Modified:
    trunk/gcc/ChangeLog
    trunk/gcc/tree-profile.c

...resulted in a number of profile related testsuite regressions on darwin.
These are all of the form...

ld: symbol(s) not found

Reverting r157822 eliminates these failures. These are surprising since darwin
should now provide all of the additional emutls symbols via a versioned
libgcc_ext shared library.

On x86_64-apple-darwin10, current gcc trunk produces...

[MacPro:darwin_objdir/x86_64-apple-darwin10.3.0/libgcc] howarth% nm
libgcc_s.1.dylib | grep emutls
00013e70 T ___emutls_get_address
00014070 T ___emutls_register_common
00013e20 t _emutls_destroy
00013de0 t _emutls_init
00015100 b _emutls_key
000150a0 d _emutls_mutex
000150fc b _emutls_size

[MacPro:darwin_objdir/x86_64-apple-darwin10.3.0/libgcc] howarth% nm
libgcc_ext.10.5.dylib | grep emutls
00013e70 T ___emutls_get_address
00014070 T ___emutls_register_common

The undefined ___emutls_v.__gcov_indirect_call_counters and
___emutls_v.__gcov_indirect_call_callee symbols occur for the following
permutations...

1) r157820 with r157822 applied (where libgcc is built with only
-DHAVE_CC_TLS).
2) r157822 (where libgcc is built with both -DHAVE_CC_TLS and -DUSE_EMUTLS)
3) r157822 with the following patch applied to invert the logic of that commit
so that neither -DHAVE_CC_TLS  or -DUSE_EMUTLS are used in building libgcc)
