--- Comment #10 from vincenzo Innocente <vincenzo.innocente at cern dot ch> 2011-09-13 09:52:53 UTC --- resurrecting this: just checked with gcc version 4.7.0 20110910 -mveclibabi=svml -LwhereverYouhaveIntelSoftware/linux/x86_64/Compiler/11.1/072/lib/intel64/ -lsvml -lirc and sincos does not vectorize nor emits svml symbols (sin, cos independently are ok)
