cd73f2c992 Add xxpermdi
This patch adds the xxpermdi instruction.  The instruction
uses bits 22, 23, 29 and 30 for non-opcode fields (DM, AX
and BX).  This results in overloading of the opcode table
with aliases, which can be seen in the GEN_XX3FORM_DM
macro.

97577fd4c3 cpu: Move cpu state syncs up into cpu_dump_state()
The x86 and ppc targets call cpu_synchronize_state() from their
*_cpu_dump_state() callbacks to ensure that up to date state is dumped
when KVM is enabled (for example when a KVM internal error occurs).

Move this call up into the generic cpu_dump_state() function so that
other KVM targets (namely MIPS) can take advantage of it.

This requires kvm_cpu_synchronize_state() and cpu_synchronize_state() to
be moved out of the #ifdef NEED_CPU_H in <sysemu/kvm.h> so that they're
accessible to qom/cpu.c.

36f48d9c78 PPC: Depend behavior of cmp instructions only on instruction encoding
When running an L=1 cmp instruction on a 64bit PPC CPU with SF off, it
still behaves identical to what it does when SF is on. Remove the implicit
difference in the code.

Also, on most 32bit CPUs we should always treat the compare as 32bit
compare, as the CPU will ignore the L bit. This is not true for e500mc,
but that's up for a different patch.

7d08d85645 target-ppc: add support for extended mtfsf/mtfsfi forms
Power ISA 2.05 adds support for extended mtfsf/mtfsfi form, with a new
W field to select the upper part of the FPCSR register.

For that the helper is changed to handle 64-bit input values and mask with
up to 16 bits. The mtfsf/mtfsfi instructions do not have the W bit
marked as invalid anymore. Instead this is checked in the helper, which
therefore needs to access to the insns/insns_flags2. They are added in
the DisasContext struct. Finally change all accesses to the opcode fields
through extract helpers, prefixed with FP for consistency.

9baea4a303 target-ppc: Remove vestigial PowerPC 620 support
The PowerPC 620 was the very first 64-bit PowerPC implementation, but
hardly anyone ever actually used the chips.  qemu notionally supports the
620, but since we don't actually have code to implement the segment table,
the support is broken (quite likely in other ways too).

This patch, therefore, removes all remaining pieces of 620 support, to
stop it cluttering up the platforms we actually care about.  This includes
removing support for the ASR register, used only on segment table based
machines.

8e33944f8c PPC: Unify dcbzl code path
The bit that makes a dcbz instruction a dcbzl instruction was declared as
reserved in ppc32 ISAs. However, hardware simply ignores the bit, making
code valid if it simply invokes dcbzl instead of dcbz even on 750 and G4.

Thus, mark the bit as unreserved so that we properly emulate a simple dcbz
in case we're running on non-G5s.

While at it, also refactor the code to check the 970 special case during
runtime. This way we don't need to differenciate between a 970 dcbz and
any other dcbz anymore. We also allow for future improvements to add e500mc
dcbz handling.

f0cc4aa845 PPC: Fix missing TRACE exception
This patch fixes bug 1031698 :
https://bugs.launchpad.net/qemu/+bug/1031698

If we look at the (truncated) translation of the conditional branch
instruction in the test submitted in the bug post, the call to the
exception helper is missing in the "bne-false" chunk of translated
code :

IN:
bne-    0x1800278

OUT:
0xb544236d:  jne    0xb5442396

0xb5442373:  mov    %ebp,(%esp)
0xb5442376:  mov    $0x44,%ebx
0xb544237b:  mov    %ebx,0x4(%esp)
0xb544237f:  mov    $0x1800278,%ebx
0xb5442384:  mov    %ebx,0x25c(%ebp)
0xb544238a:  call   0x827475a
                     ^^^^^^^^^^^^^^^^^^

0xb5442396:  mov    %ebp,(%esp)
0xb5442399:  mov    $0x44,%ebx
0xb544239e:  mov    %ebx,0x4(%esp)
0xb54423a2:  mov    $0x1800270,%ebx
0xb54423a7:  mov    %ebx,0x25c(%ebp)

Indeed, gen_exception(ctx, excp) called by gen_goto_tb (called by
gen_bcond) changes ctx->exception's value to excp's :

gen_bcond()
{
  gen_goto_tb(ctx, 0, ctx->nip + li - 4);
  /* ctx->exception value is POWERPC_EXCP_BRANCH */

  gen_goto_tb(ctx, 1, ctx->nip);
  /* ctx->exception now value is POWERPC_EXCP_TRACE */
}

Making the following gen_goto_tb()'s test false during the second call :

if ((ctx->singlestep_enabled &
    (CPU_BRANCH_STEP | CPU_SINGLE_STEP)) &&
    ctx->exception == POWERPC_EXCP_BRANCH /* false...*/) {
         target_ulong tmp = ctx->nip;
         ctx->nip = dest;
         /* ... and this is the missing call */
         gen_exception(ctx, POWERPC_EXCP_TRACE);
         ctx->nip = tmp;
}

So the patch simply adds the missing matching case, fixing our problem.

3030442054 target-ppc: Extend FPU state for newer POWER CPUs
This patch adds some extra FPU state to CPUPPCState.  Specifically,
fpscr is extended to a target_ulong bits, since some recent (64 bit)
CPUs now have more status bits than fit inside 32 bits.  Also, we add
the 32 VSR registers present on CPUs with VSX (these extend the
standard FP regs, which together with the Altivec/VMX registers form a
64 x 128bit register file for VSX).

We don't actually support the instructions using these extra registers
in TCG yet, but we still need a place to store the state so we can
sync it with KVM and savevm/loadvm it.  This patch updates the savevm
code to not fail on the extended state, but also does not actually
save it - that's a project for another patch.

This feature mask is 64 bits long and we just successfully exceeded those 64

The easiest solution that came to my mind was to simply add another 64 bits
that we can also match on. Since the comparison is only done on start of the

on any performance penalties here.

Function gen_pc_load was introduced in commit
d2856f1ad4.
The only reason for parameter searched_pc was
a debug statement in target-i386/translate.c.

Parameter puc was needed by target-sparc until
commit d7da2a1040.

Remove searched_pc from the debug statement and remove both
parameters from the parameter list of gen_pc_load.

As the function name gen_pc_load was also misleading,
it is now called restore_state_to_opc. This new name
was suggested by Peter Maydell, thanks.

v2: Remove last parameter, too, and rename the function.

bb593904c1 Parse SDR1 on mtspr instead of at translate time
On ppc machines with hash table MMUs, the special purpose register SDR1
contains both the base address of the encoded size (hashed) page tables.

At present, we interpret the SDR1 value within the address translation
path.  But because the encodings of the size for 32-bit and 64-bit are
different this makes for a confusing branch on the MMU type with a bunch
of curly shifts and masks in the middle of the translate path.

This patch cleans things up by moving the interpretation on SDR1 into the
helper function handling the write to the register.  This leaves a simple
pre-sanitized base address and mask for the hash table in the CPUState
structure which is easier to work with in the translation path.

This makes the translation path more readable.  It addresses the FIXME
comment currently in the mtsdr1 helper, by validating the SDR1 value during
interpretation.  Finally it opens the way for emulating a pSeries-style

eaabeef268 Correct ppc popcntb logic, implement popcntw and popcntd
qemu already includes support for the popcntb instruction introduced
in POWER5 (although it doesn't actually allow you to choose POWER5).

However, the logic is slightly incorrect: it will generate results
truncated to 32-bits when the CPU is in 32-bit mode.  This is not
normal for powerpc - generally arithmetic instructions on a 64-bit
powerpc cpu will generate full 64 bit results, it's just that only the
low 32 bits will be significant for condition codes.

This patch corrects this nit, which actually simplifies the code slightly.

In addition, this patch implements the popcntw and popcntd
instructions added in POWER7, in preparation for allowing POWER7 as an
emulated CPU.

efdef95fee Implement PowerPC slbmfee and slbmfev instructions
For a 64-bit PowerPC target, qemu correctly implements translation
through the segment lookaside buffer.  Likewise it supports the
slbmte instruction which is used to load entries into the SLB.

However, it does not emulate the slbmfee and slbmfev instructions
which read SLB entries back into registers.  Because these are
only occasionally used in guests (mostly for debugging) we get
away with it.

However, given the recent SLB cleanups, it becomes quite easy to
implement these, and thereby allow, amongst other things, a guest
Linux to use xmon's command to dump the SLB.

33890b3e0d target-ppc: fix evmergelo and evmergelohi
For 32-bit PPC targets, we translated:

evmergelo rX, rX, rY

as:

rX-lo = rY-lo
rX-hi = rX-lo

which is wrong, because we should be transferring rX-lo first.  This
problem is fixed by swapping the order in which we write the parts of
rX.

Similarly, we translated:

evmergelohi rX, rX, rY

as:

rX-lo = rY-hi
rX-hi = rX-lo

In this case, we can't swap the assignment statements, because that
would just cause problems for:

evmergelohi rX, rY, rX

Instead, we detect the first case and save rX-lo in a temporary
variable:

tmp = rX-lo
rX-lo = rY-hi
rX-hi = tmp

These problems don't occur on PPC64 targets because we don't split the
SPE registers into hi/lo parts for such targets.

d12d51d5ba Clean up debugging code #ifdefs (Eduardo Habkost)
Use macros to avoid #ifdefs on debugging code.

This patch doesn't try to merge logging macros from different files,
but just unify the debugging code #ifdefs onto a macro on each file. A
further cleanup can unify the debugging macros on a common header, later

df9247b264 tcg_temp_local_new should take no parameter
This patch removes useless type information in some calls to
tcg_temp_local_new.  It also removes the parameter from the
macro declaration;  if a target has to use a specific non-default
size then it should use tcg_temp_local_new_{i32,i64}.

Rework the memory load/store:
- Unify load/store functions for 32-bit and 64-bit CPU
- Don't swap values twice for bit-reverse load/store functions
  in little endian mode.
- On a 64-bit CPU in 32-bit mode, do the address truncation for
  address computation instead of every load store. Truncate the
  address when incrementing the address (if needed)
- Cache writes to access_types.
- Add a few missing calls to gen_set_access_type()
