[ include/opcode/ChangeLog ] 2002-12-30 Chris Demetriou * mips.h: Document "+" as the start of two-character operand type names, and add new "K", "+A", "+B", and "+C" operand types. (OP_MASK_INSMSB, OP_SH_INSMSB, OP_MASK_EXTMSB) (OP_SH_EXTMSB, INSN_ISA32R2, ISA_MIPS32R2, CPU_MIPS32R2): New defines. [ opcodes/ChangeLog ] 2002-12-30 Chris Demetriou * mips-dis.c (mips_cp0_names_mips3264r2, mips_hwr_names_numeric) (mips_hwr_names_mips3264r2): New arrays. (mips_arch_choice): New "hwr_names" member. (mips_arch_choices): Adjust for structure change, and add a new entry for "mips32r2" ISA. (mips_hwr_names): New variable. (set_default_mips_dis_options): Set mips_hwr_names. (parse_mips_dis_option): New "hwr-names" option which sets mips_hwr_names, and adjust "reg-names=ARCH" to set mips_hwr_names. (print_insn_arg): Change return type to "int" and use that to indicate number of characters consumed. Add support for "+" operand extension character, "+A", "+B", "+C", and "K" operands. (print_insn_mips): Adjust for changes to print_insn_arg. (print_mips_disassembler_options): Adjust for "hwr-names" addition and "reg-names" change. * mips-opc (I33): New define (shorthand for INSN_ISA32R2). (mips_builtin_opcodes): Note that "nop" and "ssnop" are special forms of "sll". Add new MIPS32 Release 2 instructions: ehb, di, ei, ext, ins, jr.hb, jalr.hb, mfhc1, mfhc2, mthc1, mthc2, rdhwr, rdpgpr, seb, seh, synci, wrpgpr, wsbh. Note that hardware rotate instructions (ror, rorv) can be used on MIPS32 Release 2, and add the official mnemonics for them (rotr, rotrv) and the similar "rotl" mnemonic for left-rotate. --- include/elf/ChangeLog | 4 ++++ include/elf/mips.h | 3 +++ include/opcode/ChangeLog | 8 ++++++++ include/opcode/mips.h | 24 ++++++++++++++++++++++-- 4 files changed, 37 insertions(+), 2 deletions(-) diff --git a/include/elf/ChangeLog b/include/elf/ChangeLog index 87e8a3b..c16c927 100644 --- a/include/elf/ChangeLog +++ b/include/elf/ChangeLog @@ -1,3 +1,7 @@ +2002-12-30 Chris Demetriou + + * mips.h (E_MIPS_ARCH_32R2): New define. + 2002-12-24 Dmitry Diky * common.h: Define msp430 machine numbers. diff --git a/include/elf/mips.h b/include/elf/mips.h index 81451ab..964c59a1 100644 --- a/include/elf/mips.h +++ b/include/elf/mips.h @@ -145,6 +145,9 @@ END_RELOC_NUMBERS (R_MIPS_maxext) /* -mips64 code. */ #define E_MIPS_ARCH_64 0x60000000 +/* -mips32r2 code. */ +#define E_MIPS_ARCH_32R2 0x70000000 + /* The ABI of the file.
