This series amends the R5900 support with the following changes: - MFLO1, MFHI1, MTLO1 and MTHI1 are generated in gen_HILO1_tx79 instead of the generic gen_HILO.
- DIV1 and DIVU1 are generated in gen_div1_tx79 instead of the generic gen_muldiv. - MOVN, MOVZ, MFHI, MFLO, MTHI, MTLO, MULT, MULTU, DIV, DIVU, DMULT, DMULTU, DDIV, DDIVU and JR are decoded in decode_opc_special_tx79 instead of the generic decode_opc_special_legacy. - Guard check_insn_opc_user_only with INSN_R5900 check. - Guard check_insn with INSN_R5900 check. - Fix HI[ac] and LO[ac] 32-bit truncation with the MIPS64 DSP ASE. This series has been successfully built with the 8 different build configurations {gcc,clang} x -m64 x mips{,64}el-{linux-user,softmmu} in addition successfully completing the R5900 test suite cd tests/tcg/mips/mipsr5900 && make check Changes in v2: - Fix HI and LO 32-bit truncation with the MIPS64 DSP ASE - Decode special R5900 opcodes in decode_opc_special_tx79 - Guard check_insn_opc_user_only with INSN_R5900 check - Guard check_insn with INSN_R5900 check Fredrik Noring (6): target/mips: Fix decoding mechanism of R5900 MFLO1, MFHI1, MTLO1 and MTHI1 target/mips: Fix decoding mechanism of R5900 DIV1 and DIVU1 target/mips: Fix HI[ac] and LO[ac] 32-bit truncation with MIPS64 DSP ASE target/mips: Fix decoding mechanism of special R5900 opcodes target/mips: Guard check_insn_opc_user_only with INSN_R5900 check target/mips: Guard check_insn with INSN_R5900 check target/mips/translate.c | 229 +++++++++++++++++++++++++++++----------- 1 file changed, 170 insertions(+), 59 deletions(-) -- 2.18.1
