printing references the symbol table to determine whether the
instruction resides in a block regular instructions or mips16
instructions. However, when the disassembler gets used in other
environments where the symbol table is not present, we no longer
rely in the symbol table, rather, use the low bit of the
instructions address to guess. There should be no change for usage
of the disassembler in host based programse, gdb ,objdump.
(print_insn_big_mips): ditto.
(print_insn_mips): ditto
* m10300-opc.c (USP, SSP, MSP, PC, IMM4, EPSW, RN0, RM1): New
operands for the am33.
(mn10300_opcodes): Add new instructions from the am33.
end-sanitize-am33
* m10300-opc.c (mn10300_opcodes): Change opcode for "syscall".
Snapshot current work.

* gas/mips/delay.d: Add -mcpu=NNNN to gas flags to let test case
run on differently targeted assembler.
* gas/mips/{ld-ilocks-addr32,ld-svr4pic.d}: Ditto.
* gas/mips/{ld-xgot.d,lif-svr4pic.d,lif-xgot.d}: Same.
* gas/mips/{mips16.d,mips4.d,nodelay.d}: Again.
* gas/mips/{trunc.d,uld.d,ulh-xgot.d,usd.d}: And then some.
* gas/mips/ld-ilocks.d: Removed disassembler flags to let target
defaults go unmodified. Replaced $f4/$f5 with $fp[45], as the
original `ld.d' had. Find `ld.s'.
* gas/mips/mul-ilocks.d: Nearly ditto.
* sky-pke.c(read_pke_pcx): return index of current pc
* sky-pke.h: export read_pke_pcx
* interp.c(sim_fetch_registers): read pke pc/pcx
* sky-libvpe.c: track name change from GDB
* sim-main.h: add vif memory based pc
- extend gdb comm area for fifo breakpoints
- define SIM_ENGINE_RESTART_HOOK
* sky-gdb.c: add support for VIF breakpoints
* gdbtk.c (gdbtk_init): Add elements to the auto_path AS LIST
ELEMENTS. This allows gdbtk to work when installed in a directory
which has a space in the path. D. Moseley pointed out the bug.
* app.c (do_scrub_begin): If tc_symbol_chars is defined, treat all
characters in it as LEX_IS_SYMBOL_COMPONENT.
* config/tc-i386.h (tc_symbol_chars): Define.
(extra_symbol_chars): Declare.
* config/tc-i386.c (extra_symbol_chars): Define.
(comment_chars): Don't use '/' as comment start if TE_LINUX.
(line_comment_chars): Set to '/' if TE_LINUX.
* doc/c-i386.texi (i386-prefixes): Update.
* doc/internals.texi (CPU backend): Document tc_symbol_chars.
Tue Jun 16 09:03:37 1998 Frank Ch. Eigler <fche@cygnus.com>
* t-cop2.s: Reorder instruction blocks to prevent "Out of bounds"
messages during test execution. Added dummy branch labels for BC2*
instructions.
* t-cop2.brn: Use --sky-debug option instead of env var.
* t-cop2.vuexpect: Updated for with new disassembly format.
* sky_sce_fast.exp: Don't compare GIF outputs for
--float-type=fast.
* sce_test{17,33,49}.dvpasm: Use ".DmaPackVif 1" option to
exercise assembler / PKE.
* rw-vureg.c: Cast memcpy operand to allay warning.
Wed Jun 10 18:04:35 1998 Frank Ch. Eigler <fche@cygnus.com>
* gdbtypes.c (get_discrete_bounds): Assign unsigned type flag for
all-positive enum.
(create_set_type): Ditto for all-positive set values.
* values.c (unpack_field_as_long): Check for typedef in struct
field unpacking.
CUR_SYMBOL_VALUE as CORE_ADDR instead of long
* buildsym.[ch]: export pending_blocks list
* tm-txvu.h: define TARGET_READ_SP and TARGET_WRITE_SP
* txvu-tdep.c: rewrite symtabs to support N_FUN symbols in overlays.
(Actually, the last version did this for N_SLINE symbols).
(txvu_read_sp,txvu_write_sp): new
* i386-dis.c: Don't print opcode suffix when we can figure out the
size (and gas can!) by register operands, or from the default
size.
(putop): Handle 'A', 'B', 'L', 'P', 'Q', 'R' macros. Rename 'C'
macro to 'E'.
(dis386, dis386_twobyte, grps): Use new suffix macros.
(dis386): Correct imul Ib to imul sIb. Change jnl to jge to be
consistent. Add suffix for call, jmp, lcall, ljmp, iret. Reverse
order of cmps operands to agree with Intel docs. Correct operand
of aad and aam (Ib -> sIb). Change ud2b from 0fb8 to 0fb9 to
agree with Intel docs.
(print_insn_x86): Print orphan fwait before other prefixes.
Return correct byte count for orphan fwait with prefixes. Don't
print `bound' operands in reverse order.
(ckprefix): Stop accumulating prefixes if we get fwait.
(OP_DIR): Print `$' before Ap operands of ljmp, lcall.
* i386.h (i386_optab): Add general form of aad and aam. Add ud2a
and ud2b.
(i386_regtab): Allow cr0..7, db0..7, dr0..7, tr0..7, not just
those that happen to be implemented on pentiums.
