Thomas Huth 4f02d49a80 disas/libvixl: Fix fall-through annotation for GCC >= 7
For compiling with -Wimplicit-fallthrough we need to fix the
fallthrough annotations in the libvixl code. This is based on
the following upstream vixl commit by Martyn Capewell:

 https://git.linaro.org/arm/vixl.git/commit/?id=de326f850f736c3a337

 "GCC 7 enables switch/case fallthrough checking, but this fails in
  VIXL, because the annotation we use is Clang specific.

  Also, fix a missing annotation in the disassembler."

Peter Maydell 437588d81d disas/capstone: Fix monitor disassembly of >32 bytes
If we're using the capstone disassembler, disassembly of a run of
instructions more than 32 bytes long disassembles the wrong data for
instructions beyond the 32 byte mark:

(qemu) xp /16x 0x100
0000000000000100: 0x00000005 0x54410001 0x00000001 0x00001000

0x00000114: 00000004 andeq r0, r0, r4
0x00000118: 54410002 strbpl r0, [r1], #-2
0x0000011c: 3c000000 .byte 0x00, 0x00, 0x00, 0x3c
0x00000120: 54410001 strbpl r0, [r1], #-1
0x00000124: 00000001 andeq r0, r0, r1
0x00000128: 00001000 andeq r1, r0, r0

0x0000013c: 00000000 andeq r0, r0, r0

Here the disassembly of 0x120..0x13f is using the data that is in
0x104..0x123.

This is caused by passing the wrong value to the read_memory_func().
The intention is that at this point in the loop the 'cap_buf' buffer
already contains 'csize' bytes of data for the instruction at guest
addr 'pc', and we want to read in an extra 'tsize' bytes.  Those
extra bytes are therefore at 'pc + csize', not 'pc'.  On the first
time through the loop 'csize' happens to be zero, so the initial read
of 32 bytes into cap_buf is correct and as long as the disassembly
never needs to read more data we return the correct information.

Use the correct guest address in the call to read_memory_func().

We are already including -D__STDC_LIMIT_MACROS in the global CXXFLAGS,
so it makes sense to do the same for -D__STDC_CONSTANT_MACROS and
-D__STDC_FORMAT_MACROS instead of limiting that to libvixl.

The -Wno-sign-compare option can also be removed since GCC 4.6 is not
supported anymore.

Paul A. Clarke 31eb7dddac ppc: Add support for 'mffsl' instruction
ISA 3.0B added a set of Floating-Point Status and Control Register (FPSCR)
instructions: mffsce, mffscdrn, mffscdrni, mffscrn, mffscrni, mffsl.
This patch adds support for 'mffsl'.

'mffsl' is identical to 'mffs', except it only returns mode, status, and enable
bits from the FPSCR.

On CPUs without support for 'mffsl' (below ISA 3.0), the 'mffsl' instruction
will execute identically to 'mffs'.

Note: I renamed FPSCR_RN to FPSCR_RN0 so I could create an FPSCR_RN mask which
is both bits of the FPSCR rounding mode, as defined in the ISA.

I also fixed a typo in the definition of FPSCR_FR.

v4:
- nit: added some braces to resolve a checkpatch complaint.

v3:
- Changed tcg_gen_and_i64 to tcg_gen_andi_i64, eliminating the need for a
  temporary, per review from Richard Henderson.

v2:
- I found that I copied too much of the 'mffs' implementation.
  The 'Rc' condition code bits are not needed for 'mffsl'.  Removed.
- I now free the (renamed) 'tmask' temporary.
- I now bail early for older ISA to the original 'mffs' implementation.

disas/riscv: Disassemble reserved compressed encodings as illegal
Due to the design of the disassembler, the immediate is not
known during decoding of the opcode; so to handle compressed
encodings with reserved immediate values (non-zero), we need
to add an additional check during decompression to match
reserved encodings with zero immediates and translate them
into the illegal instruction.

The following compressed opcodes have reserved encodings with
zero immediates: c.addi4spn, c.addi, c.lui, c.addi16sp, c.srli,
c.srai, c.andi and c.slli

Aleksandar Markovic 75199b402c disas: nanoMIPS: Fix order of more invocations
Fix order of extraction function invocations so that extraction
goes from MSB side to LSB side of the given instruction coding
content. This is desireable because of consistency and easier
visual spotting of errors.

After this patch, all such invocations should be in the desired
order.

Fix wrong function name. The convention in these files is that names of
extraction functions should reflect bit patterns they are extracting.

Aleksandar Markovic e0669eec80 disas: nanoMIPS: Remove functions that are not used
Some functions were not used at all. Compiler doesn't complain
since they are class memebers. Remove them - no future usage is
planned.
