These seems too long for review. Could we separate them into multiple pieces, for example: - The first patch just adds "-mlsx" and "-mlasx" options. - The second patch adds memory load and store instructions, and block move & store operations using these instructions. - The third patch adds integer vector add/subtraction/multiplication instructions. - The fourth patch adds integer vector division instructions (division is "complex" so IMO it worthy a separate patch) - ... - The (n-1)-th patch adds remaining instructions (impossible or difficult to be modeled with RTL templates) as UNSPECs. - The n-th patch adds the built-ins. > > gcc/config.gcc | 2 +- > gcc/config/loongarch/constraints.md | 128 +- > .../loongarch/genopts/loongarch-strings | 4 + > gcc/config/loongarch/genopts/loongarch.opt.in | 16 +- > gcc/config/loongarch/lasx.md | 5147 ++++++++++++++++ > gcc/config/loongarch/lasxintrin.h | 5342 > +++++++++++++++++ > gcc/config/loongarch/loongarch-builtins.cc | 2686 ++++++++- > gcc/config/loongarch/loongarch-c.cc | 18 + > gcc/config/loongarch/loongarch-def.c | 6 + > gcc/config/loongarch/loongarch-def.h | 9 +- > gcc/config/loongarch/loongarch-driver.cc | 10 + > gcc/config/loongarch/loongarch-driver.h | 2 + > gcc/config/loongarch/loongarch-ftypes.def | 666 +- > gcc/config/loongarch/loongarch-modes.def | 39 + > gcc/config/loongarch/loongarch-opts.cc | 89 +- > gcc/config/loongarch/loongarch-opts.h | 3 + > gcc/config/loongarch/loongarch-protos.h | 35 + > gcc/config/loongarch/loongarch-str.h | 3 + > gcc/config/loongarch/loongarch.cc | 4615 +++++++++++++- > gcc/config/loongarch/loongarch.h | 117 +- > gcc/config/loongarch/loongarch.md | 56 +- > gcc/config/loongarch/loongarch.opt | 16 +- > gcc/config/loongarch/lsx.md | 4490 ++++++++++++++ > gcc/config/loongarch/lsxintrin.h | 5181 ++++++++++++++++ > gcc/config/loongarch/predicates.md | 333 +- > 25 files changed, 28723 insertions(+), 290 deletions(-) > create mode 100644 gcc/config/loongarch/lasx.md > create mode 100644 gcc/config/loongarch/lasxintrin.h > create mode 100644 gcc/config/loongarch/lsx.md > create mode 100644 gcc/config/loongarch/lsxintrin.h > -- Xi Ruoyao <xry...@xry111.site> School of Aerospace Science and Technology, Xidian University
