From 81a0a3b4405062a30fc67c377265a9c7a3999d04 Mon Sep 17 00:00:00 2001 From: Chris Demetriou Date: Fri, 31 May 2002 01:17:17 +0000 Subject: [PATCH] [ 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. --- include/opcode/ChangeLog | 8 ++++++++ include/opcode/mips.h | 26 +++++++++++++++++++++++++- 2 files changed, 33 insertions(+), 1 deletion(-) diff --git a/include/opcode/ChangeLog b/include/opcode/ChangeLog index 100c886a7..2b0d5527e 100644 --- a/include/opcode/ChangeLog +++ b/include/opcode/ChangeLog @@ -1,3 +1,11 @@ +2002-05-30 Chris G.
