[ gas/ChangeLog ]
* config/tc-mips.c (mips_set_options, mips_opts, file_ase_dspr2, ISA_SUPPORTS_DSPR2_ASE, MIPS_CPU_ASE_DSPR2): Add DSP R2 ASE support. (macro_build): Add case '2'. (macro): Expand M_BALIGN to nop, packrl.ph or balign. (validate_mips_insn): Add support for balign instruction. (mips_ip): Handle DSP R2 instructions. Support balign instruction. (OPTION_DSPR2, OPTION_NO_DSPR2, OPTION_COMPAT_ARCH_BASE, md_parse_option, mips_after_parse_args): Add -mdspr2 and -mno-dspr2 command line options. (s_mipsset): Add support for .set dspr2 and .set nodspr2 directives. (md_show_usage): Add -mdspr2 and -mno-dspr2 help output. * doc/c-mips.texi, doc/as.texinfo: Document -mdspr2, -mno-dspr2, .set dspr2, .set nodspr2. [ gas/testsuite/ChangeLog ] * gas/mips/mips32-dspr2.s, gas/mips/mips32-dspr2.d: New test for DSP R2. * gas/mips/mips.exp: Run new test. [ include/opcode/Changelog ] * mips.h (OP_SH_BP, OP_MASK_BP): Add support for balign instruction. (INSN_DSPR2): Add flag for DSP R2 instructions. (M_BALIGN): New macro. [ opcodes/ChangeLog ] * mips-dis.c (mips_arch_choices): Add DSP R2 support. (print_insn_args): Add support for balign instruction. * mips-opc.c (D33): New shortcut for DSP R2 instructions. (mips_builtin_opcodes): Add DSP R2 instructions. [ sim/mips/ChangeLog ] * Makefile.in (IGEN_INCLUDE): Add dsp2.igen. * configure.ac (mips*-sde-elf*, mipsisa32r2*-*-*, mipsisa64r2*-*-*): Add dsp2 to sim_igen_machine. * configure: Regenerate. * dsp.igen (do_ph_op): Add MUL support when op = 2. (do_ph_mulq): New function to support mulq_rs.ph and mulq_s.ph. (mulq_rs.ph): Use do_ph_mulq. (MFHI, MFLO, MTHI, MTLO): Move these instructions to mips.igen. * mips.igen: Add dsp2 model and include dsp2.igen. (MFHI, MFLO, MTHI, MTLO): Extend these instructions for for *mips32r2, *mips64r2, *dsp. (MADD, MADDU, MSUB, MSUBU, MULT, MULTU): Extend these instructions for *mips32r2, *mips64r2, *dsp2. * dsp2.igen: New file for MIPS DSP REV 2 ASE. [ sim/testsuite/sim/mips/ChangeLog ] * basic.exp: Run the dsp2 test. * utils-dsp.inc (dspckacc_astio, dspck_tsimm): New macro. * mips32-dsp2.s: New test.
