c - why XLC compiler on bluegene/q doesn't support '-qtm'? -
i have problem xlc compiler on bluegene/q. version of xlc compiler 12.1:
ibm xl c/c++ blue gene, v12.1 version: 12.01.0000.0000
according document1, should support compiler option "-qtm", used enable transactional memory. however, got following error message:
option -qtm not valid. enter xlc_r list of valid options.
how can figure out? appreciated.
are invoking compiler bgxlc ?
