* config/tc-i386.c (optimize_imm): Adjust immediates to only those
permissible for the selected instruction suffix.
(process_suffix): For DefaultSize instructions, suppressing the
guessing of a 'q' suffix if the instruction doesn't support it is
pointless, because only an 'l' suffix can be guessed in this place.

* gas/i386/x86-64-inval.[sl]: Remove sahf/lahf.

* i386.h: CpuNo64 mov can't reasonably have a 'q' suffix. Moves
to/from test registers are illegal in 64-bit mode. Add missing
NoRex64 to sidt. fxsave/fxrstor now allow for a 'q' suffix
(previously one had to explicitly encode a rex64 prefix). Re-enable
lahf/sahf in 64-bit mode as at least some Athlon64/Opteron steppings
support it there. Add cmpxchg16b as per Intel's 64-bit documentation.

* rs6000-tdep.c (skip_prologue): Use line table info to skip over
compiler generated function calls made as part of a prologue.
* inf-ttrace.h: New file.
* hppa-hpux-nat.c [HAVE_TTRACE]: Include <sys/ttrace>.
Include "inf-ttrace.h".
(ss_mpsfu_high): Define to ss_tlsp if necessary.
(hppa_hpux_fetch_register, hppa_hpux_store_register): Use
ptid_get_pid instead of PIDGET. Modify to handle both ttrace and
ptrace systems.
(_initialize_hppa_hpux_nat) [HAVE_TTRACE]: Call inf_ttrace_traget
instead of inf_ptrace_target.
* config/pa/hpux.mh (NATDEPFILES): Add inf-ttrace.o.
* Makefile.in (inf_ttrace_h): New variable.
(hppa-hpux-nat.o): Update dependency.
(inf-ttrace.o): New dependency.
(ALLDEPFILES): Add inf-ptrace.c and inf-ttrace.c.
(sparc32_frame_cache): For functions where there is no debugging
information to help us determine whether it's a struct-return
function or not, fallback on checking whether the instruction
at the return address is an "unimp" instruction or not.
They should be correct now.
* gas/mn10300/relax.s: Add further tests of the relaxing of branch instructions.
* gas/mn10300/relax.d: Add expected relocations.

* config/tc-i386.h (CpuMMX2): Declare. Artificial classifier to
indicate the MMX extensions added by both SSE and 3DNow!A.
(Cpu3dnowA): Declare.
(CpuUnknownFlags): Update.
* config/tc-i386.c (cpu_sub_arch_name): Declare.
(cpu_arch): i586 and pentium do not imply MMX. i686 and pentiumpro do
neither imply SSE nor MMX. k6 implies MMX. k6_2 additionally implies
3DNow!. Athlon additionally implies 3DNow!A. Several new
entries (those starting with a dot are for sub-arch specification).
(set_cpu_arch): Handle sub-arch specifications.
(parse_insn): Distinguish between instructions not supported because
of insufficient CPU features and because of 64-bit mode.
* doc/c-i386.texi: Describe enhanced .arch directive.

* i386.h (i386_optab): paddq and psubq, even in their MMX form, are
available only with SSE2. Change the MMX additions introduced by SSE
and 3DNow!A to CpuMMX2 (rather than CpuMMX). Indicate the 3DNow!A
instructions by their now designated identifier (since combining i686
and 3DNow! does not really imply 3DNow!A).
