Balaji,

I am seeing a large number of libcilkrts failures on AIX.  These all
are of the form:

Executing on host: /tmp/20131103/gcc/xgcc -B/tmp/20131103/gcc/ /nasfarm/edelsohn
/src/src/gcc/testsuite/c-c++-common/cilk-plus/CK/sync_wo_spawn.c  -fno-diagnosti
cs-show-caret -fdiagnostics-color=never   -O0 -flto -g -fcilkplus -L/tmp/2013110
3/powerpc-ibm-aix7.1.0.0/./libcilkrts/.libs -fcilkplus -S  -o sync_wo_spawn.s
 (timeout = 300)
cc1: error: LTO support has not been enabled in this configuration
compiler exited with status 1

If the feature / functionality requires LTO, the tests should check
that LTO is supported with check_effective_target_lto, either in each
relevant test or in cilk-plus.exp.

Thanks, David
