--- Comment #2 from vincenzo Innocente <vincenzo.innocente at cern dot ch> 2011-06-21 10:42:01 UTC --- great! unfortunately gcc-4.7-20110528 $ patch -p0 < vect.patch patching file gcc/tree-vect-stmts.c Hunk #1 FAILED at 2089. Hunk #2 FAILED at 2099. Hunk #3 FAILED at 2134. 3 out of 3 hunks FAILED -- saving rejects to file gcc/tree-vect-stmts.c.rej so I edit gcc/tree-vect-stmts.c by hand and worked! vldexpf.cc:16: note: LOOP VECTORIZED. hope it will make it for 4.6.1 :-) I'm will wait that it gets in a snapshot to update all my machines to a new version. v.
