* interp.c (*): Adapt code to merged VU device & state structs.
(decode_coproc): Execute COP2 each macroinstruction without
pipelining, by stepping VU to completion state. Adapted to
read_vu_*_reg style of register access.
* mips.igen ([SL]QC2): Removed these COP2 instructions.
* r5900.igen ([SL]QC2): Transplanted these COP2 instructions here.
* sim-main.h (cop_[ls]q): Enclosed in TARGET_SKY guards.
end-sanitize-sky
rather than in a shell variable and using AC_SUBST.
* Makefile.am (DISTCLEANFILES): Remove ldscripts. Add tdirs.
(distclean-local): New target.
* configure, Makefile.in: Rebuild.
* i386.h: Remove NoModrm flag from all insns: it's never checked.
Add IsString flag to string instructions.
(IS_STRING): Don't define.
(LOCK_PREFIX_OPCODE, CS_PREFIX_OPCODE, DS_PREFIX_OPCODE): Define.
(ES_PREFIX_OPCODE, FS_PREFIX_OPCODE, GS_PREFIX_OPCODE): Define.
(SS_PREFIX_OPCODE): Define.
* elf32-m68k.c (elf_m68k_size_dynamic_sections): Generate section
symbols when creating a shared library.
(elf_m68k_adjust_dynindx): New function, used by above code.
(elf_m68k_finish_dynamic_sections): Initialize the section
symbols.
(elf_m68k_relocate_section): Change abort to BFD_ASSERT.
Thu Apr 2 12:47:41 1998 Frank Ch. Eigler <fche@cygnus.com>
* sol-thread.c (sol_thread_store_registers): Save & restore new
value of single updated register to prevent accidental clobbering.
* ns32k-tdep.c (flip_bytes, ns32k_localcount,
ns32k_get_enter_addr, sign_extend): Restore functions mysteriously
deleted.
* ns32knbsd-nat.c: New (?) file to support fetching and storing
registers on NetBSD hosts.
* nbsd.mh (NATDEPFILES): put ns32knbsd-nat.o instead of
ns32k-nat.o
* ns32km3-nat.c (reg_offset): Get order of floating point
registers correct. Add extra 32382 register offsets.
(REG_ADDRESS): define to point at correct part of thread
state. Use calls to "warning" instead of "message".
* tm-nbsd.h, tm-ns32km3.h (REGISTER_NAMES, NUM_REGS,
REGISTER_BYTES, REGISTER_BYTE): redefine allowing for 32382
fpu registers.
* ns32k-dis.c (bit_extract_simple): New function to extract bits
from an arbitrary valid buffer instead of fetching them on demand
using fetch_data().
(invalid_float): use bit_extract_simple() instead of bit_extract().
contributed to me for gdb 4.17.
