I am attempting to compile some inhouse code using gcc48 under FreeBSD
9.3R. The man page describes in detail how to get it to produce
multi-threaded parallel code (-apo under SGI IRIX (snif), -parallel
under icc/ifort). When I add those options to my makefile & try to use
them to compile my code, I get the following:
gcc48 -DNDEBUG -DUNDER_SCORE_SYS -DLOSE_GAMMAL -I../include -I~/inc
-I../Properties -I../TEST -I../pre -march=opteron -mtune=opteron -O3
-floop-strip-mine -floop-blo
ck -fprefetch-loop-arrays -floop-parallelize-all
-ftree-parallelize-loops=4 -fopt-info -c mpi.c mpprime.c
mpi.c:1:0: sorry, unimplemented: Graphite loop optimizations cannot be
used (-fgraphite, -fgraphite-identity, -floop-block, -floop-interchange,
-floop-strip-mine, -fl
oop-parallelize-all, and -ftree-loop-linear)

`usual' not remade because of errors.
for each 'arch' tried (opteron, barcelone, etc.). How do I find out how
to get my gcc48 to use those optimizations ? TIA & have a good one.
