Proposed patch
I've tested this patch again against rev 184764 (GCC 4.7) with
make -k check RUNTESTFLAGS="--target_board=sh-sim\{
-m2/-ml,-m2/-mb,-m2a-single/-mb,-m4-single/-ml,
-m4-single/-mb,-m4a-single/-ml,-m4a-single/-mb}"
Surprisingly, it fixes the following libstdc++ tests.
For all sub targets:
23_containers/forward_list/requirements/exception/basic.cc
23_containers/forward_list/requirements/exception/propagation_consistent.cc
23_containers/list/requirements/exception/basic.cc
23_containers/list/requirements/exception/propagation_consistent.cc
23_containers/multiset/requirements/exception/basic.cc
23_containers/multiset/requirements/exception/propagation_consistent.cc
23_containers/unordered_map/requirements/exception/propagation_consistent.cc
23_containers/unordered_multimap/requirements/exception/basic.cc
23_containers/unordered_multiset/requirements/exception/basic.cc
23_containers/unordered_multiset/requirements/exception/propagation_consistent.cc
23_containers/unordered_set/requirements/exception/propagation_consistent.cc
ext/pb_ds/regression/list_update_map_rand.cc
ext/pb_ds/regression/list_update_set_rand.cc
For -m4a-single and -m4-single (-ml and -mb):
23_containers/forward_list/requirements/exception/basic.cc
23_containers/forward_list/requirements/exception/propagation_consistent.cc
23_containers/list/requirements/exception/basic.cc
23_containers/list/requirements/exception/propagation_consistent.cc
23_containers/multiset/requirements/exception/basic.cc
23_containers/multiset/requirements/exception/propagation_consistent.cc
However, it also introduces two new of new failures.
For all sub targets:
FAIL: 21_strings/basic_string/cons/char/6.cc execution test
For -m4a-single and -m4-single (-ml and -mb):
FAIL: 22_locale/ctype/is/char/3.cc execution test
I'm looking into what is happening in the two cases.
