It is not yet properly tested.

* dv-tx3904tmr.c: New file - implements tx3904 timer.
* dv-tx3904{irc,cpu}.c: Mild reformatting.
* configure.in: Include tx3904tmr in hw_device list.
* configure: Rebuilt.
* interp.c (sim_open): Instantiate three timer instances.
Fix address typo of tx3904irc instance.
* config/tc-i386.c (END_STRING_AND_SAVE): Protect arguments of
macros and enclose in do while(0).
(RESTORE_END_STRING): Likewise.
(md_assemble): Add one to printed operand number so we start
from 1 not 0. Add some more gettext invocations.
(i386_operand): Fix `%%s' -> `%%%s'. Inc printed operand
number here too.
* config/tc-i386.h (WAIT_PREFIX, LOCKREP_PREFIX, ADDR_PREFIX,
DATA_PREFIX, SEG_PREFIX): Define.
* config/tc-i386.c (struct _i386_insn): Remove wait_prefix field.
(check_prefix): Remove function.
(add_prefix): New function. Add prefix to i.prefix as well as
doing checks.
(md_assemble): Changes for add_prefix. Remove hack for wait
prefix, instead always output prefixes in fixed order. Test
for jcxz/loop when selecting between word & dword operations,
and add address size prefix rather than operand size prefix.
Remove operand -> address size hack when emitting jcxz/loop.
(i386_operand): Remove O_Absent check as it's done in expr.
Rename from 64 bit versions, update members to be 32 bits.
(bfd_dvp_elf32_swap_overlay_in,bfd_dvp_elf32_swap_overlay_out):
Rename from 64 bit versions.
* config/tc-m68k.c (md_estimate_size_before_relax): Add more calls
to relaxable_symbol to prevent references to external symbol from
being relaxed.
Wed Jun 3 14:10:36 1998 Ian Lance Taylor <ian@cygnus.com>
* config/tc-m68k.c (relaxable_symbol): If TARGET_OS is "elf", all
symbols are relaxable.
byte-swapping unnecessary. Add -sparclite-board option for
emulating RAM found on typical SPARClite boards. Print
error message for unrecognized option.
* erc32.c: Change RAM address and size from constants to variables,
to allow emulation of SPARClite board RAM.
(fetch_bytes, store_bytes): New helper functions for revamped
mememory_read and memory_write.
(memory_read, memory_write): Rewrite to store bytes in target
byte order instead of storing words in host byte order; this
greatly simplifies support of little-endian programs.
(get_mem_ptr): Remove unnecessary byte parameter.
(sis_memory_write, sis_memory_read): Store words in target
byte order instead of host byte order.
(byte_swap_words): Remove, no longer needed.
* sis.h ((byte_swap_words): Remove declaration, no longer needed.
(memory_read): Add new sz parameter.
* sis.c (run_sim): Use revamped memory_read, which makes
byte-swapping unnecessary.
* exec.c (dispatch_instruction): Use revamped memory_read, which
makes byte-swapping and double-word fetching unnecessary.
* func.c (sparclite_board): Declare new variable.
(get_regi): Handle little-endian data.
(bfd_load): Recognize little-endian SPARClite as having
little-endian data.
* macro.c (macro_mri_mode): New function.
* macro.h (macro_mri_mode): Declare.
* read.c (s_mri): Call macro_mri_mode when switching in and out of
MRI mode.
* ppc-opc.c (powerpc_macros): Support shifts and rotates of size
0; produce error message for shifts of size 32 (or 64 for 64-bit
shifts), because the hardware doesn't support them.
* elf32-ppc.c (ppc_elf_relocate_section): The target of an
R_PPC_LOCAL24PC relocation should be local; if not, print an error
message instead of crashing.
* config/tc-vax.c (md_create_short_jump): Fix off by two bug in
offset calculation. Also, use VAX_BRW from vax-inst.h instead
of hardcoded magic number.
(md_create_long_jump): Use VAX_JMP and VAX_ABSOLUTE_MODE macros.
set endianness based on machine type.
(_initialize_sparc_tdep): Initialize target_architecture_hook.
(sparc_print_register_hook): Print PSR and FPSR in fancy format
on 32-bit machines.
* config/sparc/tm-sparc.h (PRINT_REGISTER_HOOK): Redefine to
call sparc_print_register_hook instead of using inline code.
* config/sparc/tm-sp64.h (PRINT_REGISTER_HOOK): Remove.
* armos.c (ARMul_OSHandleSWI::SWI_Open): Handle special case
of ":tt" to catch stdin in addition to stdout.
(ARMul_OSHandleSWI::SWI_Seek): Return 0 or 1 to indicate failure
or success of lseek().
From PR 15839, modified a bit by me to appease my sense of style--but
not too much because I am lazy.
* gas/mips/mips.exp: The r5900 has ilocks and gpr_ilocks.
* gas/mips/div-ilocks.d: Handle both "break" instruction variants.
* gas/mips/{div.d, mul-ilocks.d, mul.d}: Likewise.
