Pushed to r14-4730. 在 2023/10/16 上午10:00, Jiahao Xu 写道: > The following three patches further enhance loongarch’s vectorization capabilities. > > Patch one add LoongArch support for AVG_CEIL/FLOOR. > > Patch 2 add LoongArch support for vec_widen_mult/add/sub_lo/hi patterns. > > patch 3 make loongarch use the new vector hooks and implements the costing > function determine_suggested_unroll_factor, to make it be able to suggest the > unroll factor for a given loop being vectorized base vec_ops analysis during > vector costing and the available issue information.The patch also adjusts cost > model through performance analysis. > > Jiahao Xu (3): > LoongArch:Implement avg and sad standard names. > LoongArch:Implement vec_widen standard names. > LoongArch:Implement the new vector cost model framework. > > gcc/config/loongarch/genopts/loongarch.opt.in | 15 +- > gcc/config/loongarch/lasx.md | 156 ++++++++- > gcc/config/loongarch/loongarch-protos.h | 1 + > gcc/config/loongarch/loongarch.cc | 309 +++++++++++++++++- > gcc/config/loongarch/loongarch.md | 2 + > gcc/config/loongarch/loongarch.opt | 15 +- > gcc/config/loongarch/lsx.md | 74 +++++ > gcc/doc/invoke.texi | 7 + > .../gcc.target/loongarch/avg-ceil-lasx.c | 22 ++ > .../gcc.target/loongarch/avg-ceil-lsx.c | 22 ++ > .../gcc.target/loongarch/avg-floor-lasx.c | 22 ++ > .../gcc.target/loongarch/avg-floor-lsx.c | 22 ++ > gcc/testsuite/gcc.target/loongarch/sad-lasx.c | 20 ++ > gcc/testsuite/gcc.target/loongarch/sad-lsx.c | 20 ++ > .../gcc.target/loongarch/vect-widen-add.c | 26 ++ > .../gcc.target/loongarch/vect-widen-mul.c | 26 ++ > .../gcc.target/loongarch/vect-widen-sub.c | 26 ++ > 17 files changed, 746 insertions(+), 39 deletions(-) > create mode 100644 gcc/testsuite/gcc.target/loongarch/avg-ceil-lasx.c > create mode 100644 gcc/testsuite/gcc.target/loongarch/avg-ceil-lsx.c > create mode 100644 gcc/testsuite/gcc.target/loongarch/avg-floor-lasx.c > create mode 100644 gcc/testsuite/gcc.target/loongarch/avg-floor-lsx.c > create mode 100644 gcc/testsuite/gcc.target/loongarch/sad-lasx.c > create mode 100644 gcc/testsuite/gcc.target/loongarch/sad-lsx.c > create mode 100644 gcc/testsuite/gcc.target/loongarch/vect-widen-add.c > create mode 100644 gcc/testsuite/gcc.target/loongarch/vect-widen-mul.c > create mode 100644 gcc/testsuite/gcc.target/loongarch/vect-widen-sub.c >
