AFAICT
(1) the failures for libgomp.c++/pr24455.C are (at least for
x86_64-apple-darwin10)
FAIL: libgomp.c++/pr24455.C -O* (test for excess errors)
Excess errors:
Undefined symbols:
"TLS init function for i", referenced from:
TLS wrapper function for i in ccoTk54U.o
__ZTH1i$non_lazy_ptr in ccoTk54U.o
(maybe you meant: __ZTH1i$non_lazy_ptr)
ld: symbol(s) not found
(2) The error "... dynamic initialization of non-function-local ..." comes from
gcc/cp/decl2.c if ASM_OUTPUT_DEF is not defined. I see in gcc/config/darwin.c
/* The Darwin's implementation of TARGET_ASM_OUTPUT_ANCHOR. Define the
anchor relative to ".", the current section position. We cannot use
the default one because ASM_OUTPUT_DEF is wrong for Darwin. */
