Hi, This is my attempt of converting MIPS translation code into decodetree.
Currently only MIPS I to MIPS Release 5 arithmatic functions are converted. Old decoding functions are perserved in codebase for now due to dependencies from microMIPS/nanoMIPS translation code. Will remove them after dealing with release 6. Both instruction encoding and test cases are generated form MIPS's internal architecture validation tools so they are gureented to be correct. Thanks. - Jiaxun Jiaxun Yang (3): target/mips: Introduce register access helper functions target/mips: Convert legacy arithmatic instructions to decodetree tests/tcg/mips: Add mips32 arithmatic instruction test cases target/mips/tcg/insn_trans/trans_arith.c.inc | 352 ++++++++++++++++++ target/mips/tcg/legacy.decode | 62 +++ target/mips/tcg/meson.build | 1 + target/mips/tcg/translate.c | 143 ++++++- target/mips/tcg/translate.h | 54 +++ tests/tcg/mips/include/test_utils_32.h | 75 ++++ .../tcg/mips/user/isa/mips32/arithmatic/add.c | 99 +++++ .../mips/user/isa/mips32/arithmatic/addi.c | 70 ++++ .../mips/user/isa/mips32/arithmatic/addiu.c | 90 +++++ .../mips/user/isa/mips32/arithmatic/addu.c | 125 +++++++ .../tcg/mips/user/isa/mips32/arithmatic/div.c | 81 ++++ .../mips/user/isa/mips32/arithmatic/divu.c | 78 ++++ .../mips/user/isa/mips32/arithmatic/madd.c | 79 ++++ .../mips/user/isa/mips32/arithmatic/maddu.c | 78 ++++ .../mips/user/isa/mips32/arithmatic/msub.c | 78 ++++ .../mips/user/isa/mips32/arithmatic/msubu.c | 78 ++++ .../tcg/mips/user/isa/mips32/arithmatic/mul.c | 78 ++++ .../mips/user/isa/mips32/arithmatic/mult.c | 78 ++++ .../mips/user/isa/mips32/arithmatic/multu.c | 78 ++++ .../tcg/mips/user/isa/mips32/arithmatic/slt.c | 61 +++ .../mips/user/isa/mips32/arithmatic/slti.c | 48 +++ .../mips/user/isa/mips32/arithmatic/sltiu.c | 48 +++ .../mips/user/isa/mips32/arithmatic/sltu.c | 61 +++ .../tcg/mips/user/isa/mips32/arithmatic/sub.c | 104 ++++++ .../mips/user/isa/mips32/arithmatic/subu.c | 108 ++++++ 25 files changed, 2206 insertions(+), 1 deletion(-) create mode 100644 target/mips/tcg/insn_trans/trans_arith.c.inc create mode 100644 target/mips/tcg/legacy.decode create mode 100644 tests/tcg/mips/user/isa/mips32/arithmatic/add.c create mode 100644 tests/tcg/mips/user/isa/mips32/arithmatic/addi.c create mode 100644 tests/tcg/mips/user/isa/mips32/arithmatic/addiu.c create mode 100644 tests/tcg/mips/user/isa/mips32/arithmatic/addu.c create mode 100644 tests/tcg/mips/user/isa/mips32/arithmatic/div.c create mode 100644 tests/tcg/mips/user/isa/mips32/arithmatic/divu.c create mode 100644 tests/tcg/mips/user/isa/mips32/arithmatic/madd.c create mode 100644 tests/tcg/mips/user/isa/mips32/arithmatic/maddu.c create mode 100644 tests/tcg/mips/user/isa/mips32/arithmatic/msub.c create mode 100644 tests/tcg/mips/user/isa/mips32/arithmatic/msubu.c create mode 100644 tests/tcg/mips/user/isa/mips32/arithmatic/mul.c create mode 100644 tests/tcg/mips/user/isa/mips32/arithmatic/mult.c create mode 100644 tests/tcg/mips/user/isa/mips32/arithmatic/multu.c create mode 100644 tests/tcg/mips/user/isa/mips32/arithmatic/slt.c create mode 100644 tests/tcg/mips/user/isa/mips32/arithmatic/slti.c create mode 100644 tests/tcg/mips/user/isa/mips32/arithmatic/sltiu.c create mode 100644 tests/tcg/mips/user/isa/mips32/arithmatic/sltu.c create mode 100644 tests/tcg/mips/user/isa/mips32/arithmatic/sub.c create mode 100644 tests/tcg/mips/user/isa/mips32/arithmatic/subu.c -- 2.34.1
