From d28847ce8eb6da33e8bc2905fe0b08631360a764 Mon Sep 17 00:00:00 2001 From: Alexandre Oliva Date: Fri, 8 Feb 2002 05:51:04 +0000 Subject: Contribute sh64-elf. 2001-10-08 Nick Clifton * sh64-opc.c: Regenerate. 2001-03-13 DJ Delorie * sh64-opc.h: Rename A_RESV_Fx to A_REUSE_PREV so that its purpose is more obvious. * sh64-opc.c (shmedia_table): Ditto. * sh64-dis.c (initialize_shmedia_opcode_mask_table): Ditto. (print_insn_shmedia): Ditto. 2001-03-12 DJ Delorie * sh64-opc.c: Adjust comments to reflect reality: replace bits 3:0 with zeros (not "reserved"), replace "rrrrrr" with "gggggg" for two-operand floating point opcodes. Remove "fsina". 2001-01-08 Hans-Peter Nilsson * sh64-dis.c (print_insn_shmedia) : Correct printing of .byte:s. Return number of printed bytes or -1; never 0. (print_insn_sh64x) : Ditto. Print as .byte:s to next four-byte-alignment if insn or data is not aligned. 2001-01-06 Hans-Peter Nilsson * sh64-dis.c: Update comments and fix comment formatting. (initialize_shmedia_opcode_mask_table) : Abort instead of setting length to 0. (crange_qsort_cmpb, crange_qsort_cmpl, crange_bsearch_cmpb, crange_bsearch_cmpl, sh64_get_contents_type, sh64_address_in_cranges): Move to bfd/elf32-sh64.c. 2001-01-05 Hans-Peter Nilsson * sh64-opc.c: Remove #if 0:d entries for instructions not found in SH-5/ST50-023-04: fcosa.s, fsrra.s and prefo. 2000-12-30 Hans-Peter Nilsson * sh64-dis.c (print_insn_shmedia): Display MOVI/SHORI-formed address with same prefix as SHcompact. In the disassembler, use a .cranges section for linked executables. * sh64-dis.c (SAVED_MOVI_R, SAVED_MOVI_IMM): Move to head of file and update for using structure in info->private_data. (struct sh64_disassemble_info): New. (is_shmedia_p): Delete. (crange_qsort_cmpb): New function. (crange_qsort_cmpl, crange_bsearch_cmpb): New functions. (crange_bsearch_cmpl, sh64_address_in_cranges): New functions. (init_sh64_disasm_info, sh64_get_contents_type_disasm): New functions. (sh64_get_contents_type, sh64_address_is_shmedia): New functions. (print_insn_shmedia): Correct displaying of address after MOVI/SHORI pair. Display addresses for linked executables only. (print_insn_sh64x_media): Initialize info->private_data by calling init_sh64_disasm_info. (print_insn_sh64x): Ditto. Find out type of contents by calling sh64_contents_type_disasm. Display data regions using ".long" and ".byte" similar to unrecognized opcodes. 2000-12-19 Hans-Peter Nilsson * sh64-dis.c (is_shmedia_p): Check info->section and look for ISA information in section flags before considering symbols. Don't assume an info->mach setting of bfd_mach_sh5 means SHmedia code. * configure.in (bfd_sh_arch): Check presence of sh64 insns by matching $target $canon_targets instead of looking at the now-removed -DINCLUDE_SHMEDIA in $targ_cflags. * configure: Regenerate. 2000-11-25 Hans-Peter Nilsson * sh64-opc.c (shmedia_creg_table): New. * sh64-opc.h (shmedia_creg_info): New type. (shmedia_creg_table): Declare. * sh64-dis.c (creg_name): New function. (print_insn_shmedia): Use it. * disassemble.c (disassembler) [ARCH_sh, INCLUDE_SHMEDIA]: Map bfd_mach_sh5 to print_insn_sh64 if big-endian and to print_insn_sh64l if little-endian. * sh64-dis.c (print_insn_shmedia): Make r unsigned. (print_insn_sh64l): New. (print_insn_sh64x): New. (print_insn_sh64x_media): New. (print_insn_sh64): Break out code to print_insn_sh64x and print_insn_sh64x_media. 2000-11-24 Hans-Peter Nilsson * sh64-opc.h: New file * sh64-opc.c: New file * sh64-dis.c: New file * Makefile.am: Add sh64 targets. (HFILES): Add sh64-opc.h. (CFILES): Add sh64-opc.c and sh64-dis.c. (ALL_MACHINES): Add sh64 files. * Makefile.in: Regenerate. * configure.in: Add support for sh64 to bfd_sh_arch. * configure: Regenerate. * disassemble.c [ARCH_all] (INCLUDE_SHMEDIA): Define. (disassembler) [ARCH_sh, INCLUDE_SHMEDIA]: Map bfd_mach_sh5 to print_insn_sh64. * sh-dis.c (print_insn_shx): Handle bfd_mach_sh5 as arch_sh4. * po/POTFILES.in: Regenerate. * po/opcodes.pot: Regenerate. --- opcodes/sh64-opc.h | 139 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 139 insertions(+) create mode 100644 opcodes/sh64-opc.h (limited to 'opcodes/sh64-opc.h') diff --git a/opcodes/sh64-opc.h b/opcodes/sh64-opc.h new file mode 100644 index 0000000..2ed6c11 --- /dev/null +++ b/opcodes/sh64-opc.h @@ -0,0 +1,139 @@ +/* Declarations for SH64 opcodes. + Copyright (C) 2000, 2001 Free Software Foundation, Inc. + +This program is free software; you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation; either version 2 of the License, or +(at your option) any later version. + +This program is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
