Aurelien Jarno 2a6e32dd46 target-mips: make CP0_LLAddr register CPU dependent
Depending on the CPU, CP0_LLAddr is either read-only or read-write,
and the returned value can be shifted by a variable amount of bits.

Aurelien Jarno 5499b6ffac target-mips: rename CP0_LLAddr into lladdr
The variable CP0_LLAddr represent the full lladdr, not the actual
register value, which is only part of this value and depends on the
CPU.

Anthony Liguori c227f0995e Revert "Get rid of _t suffix"
In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem.  Something
like this _must_ be presented on the list first so people can provide input
and cope with it.

This reverts commit 99a0949b72.

Nathan Froyd 7b270ef2a3 target-mips: fix single-stepping
Single-stepping branches on MIPS didn't work right, because the
generation of EXCP_DEBUG happened after the generation of the code to
exit the current TB.  That is, given the code:

    bne v0,v1,target
    nop
    ...
  target:
    addu v0,v0,v1
  1:

when you single-stepped through the NOP, execution wouldn't actually
halt until you reached the label `1'.

This patch corrects that and also changes single-stepping so that a
branch and its delay slot are executed as one instruction for the
purposes of single-stepping.  This behavior is comparable to what other
MIPS tools (e.g. MIPSsim with MDI) do.  GDB avoids placing breakpoints
in branch delay slots, so this change doesn't break anything on the GDB
side.

Blue Swirl 72cf2d4f0e Fix sys-queue.h conflict for good
Problem: Our file sys-queue.h is a copy of the BSD file, but there are
some additions and it's not entirely compatible. Because of that, there have
been conflicts with system headers on BSD systems. Some hacks have been
introduced in the commits 15cc923584,
f40d753718,
96555a96d7 and
3990d09adf but the fixes were fragile.

Solution: Avoid the conflict entirely by renaming the functions and the
file. Revert the previous hacks.

Nathan Froyd fa31af0e63 target-mips: fix conditional moves off fp condition codes
Conditional moves off fp condition codes were using the result of
get_fp_bit to isolate and test the relevant condition code.  However,
get_fp_bit returns the bit number of the condition code, not a
bitmask.  (Compare the use of get_fp_bit in gen_compute_branch1, for
instance.)

Fixed by shifting a bitmask into place using the result of get_fp_bit in
the relevant functions (gen_mov{ci,cf_s,cf_d,cf_ps}).

Nathan Froyd 0b5c1ce846 cleanup cpu-exec.c, part 0/N: consolidate handle_cpu_signal
handle_cpu_signal is very nearly copy-paste code for each target, with a
few minor variations.  This patch sets up appropriate defaults for a
generic handle_cpu_signal and provides overrides for particular targets
that did things differently.  Fixing things like the persistent (XXX:
use sigsetjmp) should now become somewhat easier.

Previous comments on this patch suggest that the "activate soft MMU for
this block" comments refer to defunct functionality.  I have removed
such blocks for the appropriate targets in this patch.

aliguori a1d1bb3101 Refactor and enhance break/watchpoint API (Jan Kiszka)
This patch prepares the QEMU cpu_watchpoint/breakpoint API to allow the
succeeding enhancements this series comes with.

First of all, it overcomes MAX_BREAKPOINTS/MAX_WATCHPOINTS by switching
to dynamically allocated data structures that are kept in linked lists.
This also allows to return a stable reference to the related objects,
required for later introduced x86 debug register support.

Breakpoints and watchpoints are stored with their full information set
and an additional flag field that makes them easily extensible for use
beyond pure guest debugging.

aurel32 507563e85d target-mips: optimize gen_arith()/gen_arith_imm()
Optimize code generation in gen_arith()/gen_arith_imm():
- Don't do sign extension when the value is already guaranteed to be
  sign extended (otherwise, results are marked as UNPREDICTABLE).
- When the value is sign extended, compare the value to 0 instead of
  testing bit 31/63.
- Temp variables are valid up to and *including* the brcond instruction.
  Use them instead of temp local variables.

aurel32 49bcf33cc7 target-mips: convert bit shuffle ops to TCG
Bit shuffle operations can be written with very few TCG instructions
(between 5 and 8), so it is worth converting them to TCG.

This code also move all bit shuffle generation code to a separate
function in order to have a cleaner exception code path, that is it
doesn't store back the TCG register to the target register after the
exception, as the TCG register doesn't exist anymore.

This patch attempts to fix mft* helpers and the associated TCG calls.
mft* helpers do not take a register in argument, however:
- some helpers are called with an argument while they do not take one.
- some helpers are declared with an argument they don't use.
