Hello, The new patch is attached. A new flag was added to control complete unrolling pass (-ftree-complete-unroll). It is unset in the vectorizer testsuite. The addition of the new passes causes more testcases to PASS which changes the gcc summary report. It is caused due to a testcase like the following; which passes for every dump file that is produces, because more are produced we get more PASSes. /home/eres/build_lim_certification/new_build/gcc/xgcc -B/home/eres/build_lim_certification/new_build/gcc/ -w -O2 -DMASK=2 -x c -da -fdump-tree-all -fdump-noaddr -fno-show-column -c -O2 -o /home/eres/build_lim_certification/new_build/gcc/testsuite/gcc/dump-noaddr.o /home/eres/build_lim_certification/gcc/gcc/testsuite/gcc.c-torture/unsorted/dump-noaddr.c (timeout = 300) PASS: gcc.c-torture/unsorted/dump-noaddr.c, -O2 -DMASK=2 -x c -da -fdump-tree-all -fdump-noaddr PASS: gcc.c-torture/unsorted/dump-noaddr.c.001t.tu, -O2 comparison PASS: gcc.c-torture/unsorted/dump-noaddr.c.003t.original, -O2 comparison PASS: gcc.c-torture/unsorted/dump-noaddr.c.004t.gimple, -O2 comparison We have four more passes; their are eight different runs like that ( -O0, -O1, -O2, -O3, -O3 -fomit-frame-pointer -funroll-loops, -O3 -fomit-frame-pointer -funroll-all-loops -finline-functions, -O3 -g, -Os), which explains 32 more testcases that pass. === gcc tests === @@ -170,14 +170,14 @@ === gcc Summary === -# of expected passes 43835 +# of expected passes 43867 # of unexpected failures 68 Bootstrap and tested on PPC. OK for autovect branch? Thanks, Revital 2007-03-22 Revital Eres <eres@il.ibm.com> * passes.c (init_optimization_passes): move complete-unrolling pass before the vectorizer and add constant propagation, store-ccp, dse and dce passes after it. * common.opt (-ftree-complete-unroll): Add the new flag. * doc/invoke.texi (-ftree-complete-unroll): Document it. * testsuite/gcc.dg/vect/vect.exp: Add fno-tree-complete-unroll to the default options of the vect testsuite. * tree-ssa-loop.c (gate_tree_complete_unroll): Add -ftree-complete-unroll flag to the gate. * testsuite/gcc.dg/tree-ssa/20030917-1.c: Fix dump file number. * testsuite/gcc.dg/tree-ssa/ssa-ccp-1.c: Likewise. * testsuite/gcc.dg/tree-ssa/pr21574.c: Likewise. * testsuite/gcc.dg/tree-ssa/20030917-3.c: Likewise. * testsuite/gcc.dg/tree-ssa/ssa-ccp-3.c: Likewise. * testsuite/gcc.dg/tree-ssa/pr14841.c: Likewise. * testsuite/gcc.dg/tree-ssa/20030731-2.c: Likewise. * testsuite/gcc.dg/tree-ssa/20040721-1.c: Likewise. * testsuite/gcc.dg/pr23911.c: Likewise.
