From deec17343ce91f1274e438996bbcf19f17c1c3ac Mon Sep 17 00:00:00 2001 From: Chris Demetriou Date: Fri, 31 May 2002 01:17:18 +0000 Subject: [ gas/ChangeLog ] 2002-05-30 Chris G. Demetriou Ed Satterthwaite * config/tc-mips.c (mips_set_options): New "ase_mdmx" member. (mips_opts): Initialize "ase_mdmx" member. (file_ase_mdmx): New variable. (CPU_HAS_MDMX): New macro. (md_begin): Initialize mips_opts.ase_mdmx and file_ase_mdmx based on command line options and configuration defaults. (macro_build): Note in comment that use of MDMX in macros is not currently allowed. (validate_mips_insn): Add support for the "O", "Q", "X", "Y", and "Z" MDMX operand types. (mips_ip): Accept MDMX instructions if mips_opts.ase_mdmx is set, and add support for the "O", "Q", "X", "Y", and "Z" MDMX operand types. (OPTION_MDMX, OPTION_NO_MDMX, md_longopts, md_parse_option): Add support for "-mdmx" and "-no-mdmx" options. (OPTION_ELF_BASE): Move to accomodate new options. (s_mipsset): Support ".set mdmx" and ".set nomdmx". (mips_elf_final_processing): Set MDMX ASE ELF header flag if file_ase_mdmx was set. * doc/as.texinfo: Document -mdmx and -no-mdmx options. * doc/c-mips.texi: Likewise, and document ".set mdmx" and ".set nomdmx" directives. [ gas/testsuite/ChangeLog ] 2002-05-30 Chris G. Demetriou * gas/mips/mips64-mdmx.s: New file. * gas/mips/mips64-mdmx.d: Likewise. * gas/mips/mips.exp: Run new "mips64-mdmx" test. [ include/opcode/ChangeLog ] 2002-05-30 Chris G. Demetriou * mips.h (OP_SH_ALN, OP_MASK_ALN, OP_SH_VSEL, OP_MASK_VSEL) (MDMX_FMTSEL_IMM_QH, MDMX_FMTSEL_IMM_OB, MDMX_FMTSEL_VEC_QH) (MDMX_FMTSEL_VEC_OB, INSN_READ_MDMX_ACC, INSN_WRITE_MDMX_ACC) (INSN_MDMX): New constants, for MDMX support. (opcode character list): Add "O", "Q", "X", "Y", and "Z" for MDMX. [ opcodes/ChangeLog ] 2002-05-30 Chris G. Demetriou Ed Satterthwaite * mips-dis.c (print_insn_arg): Add support for 'O', 'Q', 'X', 'Y', and 'Z' formats, for MDMX. (mips_isa_type): Add MDMX instructions to the ISA bit mask for bfd_mach_mipsisa64. * mips-opc.c: Add support for MDMX instructions. (MX): New definition. * mips-dis.c: Update copyright years to include 2002. --- opcodes/mips-dis.c | 53 ++++++++++++++++++++++++++++++++++++++++++++++++++--- 1 file changed, 50 insertions(+), 3 deletions(-) (limited to 'opcodes/mips-dis.c') diff --git a/opcodes/mips-dis.c b/opcodes/mips-dis.c index 661c179..b832ca2 100644 --- a/opcodes/mips-dis.c +++ b/opcodes/mips-dis.c @@ -284,6 +284,53 @@ print_insn_arg (d, l, pc, info) (l >> OP_SH_SEL) & OP_MASK_SEL); break; + case 'O': + (*info->fprintf_func) (info->stream, "%d", + (l >> OP_SH_ALN) & OP_MASK_ALN); + break; + + case 'Q': + { + unsigned int vsel = (l >> OP_SH_VSEL) & OP_MASK_VSEL; + if ((vsel & 0x10) == 0) + { + int fmt; + vsel &= 0x0f; + for (fmt = 0; fmt < 3; fmt++, vsel >>= 1) + if ((vsel & 1) == 0) + break; + (*info->fprintf_func) (info->stream, "$v%d[%d]", + (l >> OP_SH_FT) & OP_MASK_FT, + vsel >> 1); + } + else if ((vsel & 0x08) == 0) + { + (*info->fprintf_func) (info->stream, "$v%d", + (l >> OP_SH_FT) & OP_MASK_FT); + } + else + { + (*info->fprintf_func) (info->stream, "0x%x", + (l >> OP_SH_FT) & OP_MASK_FT); + } + } + break; + + case 'X': + (*info->fprintf_func) (info->stream, "$v%d", + (l >> OP_SH_FD) & OP_MASK_FD); + break; + + case 'Y': + (*info->fprintf_func) (info->stream, "$v%d", + (l >> OP_SH_FS) & OP_MASK_FS); + break; + + case 'Z': + (*info->fprintf_func) (info->stream, "$v%d", + (l >> OP_SH_FT) & OP_MASK_FT); + break; + default: /* xgettext:c-format */ (*info->fprintf_func) (info->stream, @@ -378,8 +425,8 @@ mips_isa_type (mach, isa, cputype) case bfd_mach_mipsisa32: *cputype = CPU_MIPS32; /* For stock MIPS32, disassemble all applicable MIPS-specified ASEs. - Note that MIPS-3D is not applicable to MIPS32.
