Hi all,
ref: http://gcc.gnu.org/ml/gcc/2008-12/msg00107.html, PR32765 and
http://gcc.gnu.org/ml/fortran/2008-12/ msg00118.html
NOTE to gurus: the whole libgcc_eh, libgcc_s.{10.x, 1} thing is
quite hard to understand.
I searched gcc.pdf, gccint.pdf (0 hits) and the list (not much) ...
and google (mostly speculation).
In the end I had to RTSC....
If I now understand correctly, the symbols present in updated
versions of libgcc that are not in the "stock" system libgcc on
darwin - need to be mentioned in the stub libraries (ligcc_s.10.
{4,5,...} ). The emutls ones were not present causing linkage
failures that were silently UNSUPPORTING a lot of tests.
It's also possible that key tests might fail on 64bit processors (see
the referenced threads) which could also result in "UNSUPPORTS"
appearing and disappearing sporadically.
"bootstrap-lean" and "make check" on powerpc-apple-darwin8 and i386-
apple-darwin9 (both on 64 bit processors).
this results in:
g++ +1 supported
gcc +4 supported
libgomp +126 supported
I'll look at 32bit processor builds during today.
do you think this is the proper solution ?
Iain
