--- Comment #3 from seurer at gcc dot gnu.org --- I just tried this and I am still seeing failures albeit only on power 7 BE. make -k check-gcc RUNTESTFLAGS="--target_board=unix'{-m32}' vect.exp=gcc.dg/vect/bb-slp-layout-19.c" FAIL: gcc.dg/vect/bb-slp-layout-19.c scan-tree-dump-times slp1 "add new stmt: [^\\n\\r]* = VEC_PERM_EXPR" 3 FAIL: gcc.dg/vect/bb-slp-layout-19.c -flto -ffat-lto-objects scan-tree-dump-times slp1 "add new stmt: [^\\n\\r]* = VEC_PERM_EXPR" 3 # of expected passes 2 # of unexpected failures 2 Note that while that run was for 32 bits it fails for 64 as well.
