Contribute sh64-elf.

2001-10-08  Nick Clifton  <nickc@cambridge.redhat.com>
* sh64-opc.c: Regenerate.
2001-03-13  DJ Delorie  <dj@redhat.com>
* 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  <dj@redhat.com>
* 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  <hpn@cygnus.com>
* sh64-dis.c (print_insn_shmedia) <failing read_memory_func>:
Correct printing of .byte:s.  Return number of printed bytes or
-1; never 0.
(print_insn_sh64x) <not CRT_SH5_ISA16>: Ditto.  Print as .byte:s
to next four-byte-alignment if insn or data is not aligned.
2001-01-06  Hans-Peter Nilsson  <hpn@cygnus.com>
* sh64-dis.c: Update comments and fix comment formatting.
(initialize_shmedia_opcode_mask_table) <case A_IMMM>:
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  <hpn@cygnus.com>
* 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  <hpn@cygnus.com>
* 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  <hpn@cygnus.com>
* 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  <hpn@cygnus.com>
* 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  <hpn@cygnus.com>
* 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.
