ARM: fix ldrexd/strexd

Correct ldrexd and strexd code to always read and write the
high word of the 64-bit value from addr+4.
Also make ldrexd and strexd agree that for a 64 bit value the
address in env->exclusive_addr is that of the low word.

This fixes the issues reported in...

ARM: Fix decoding of VFP forms of VCVT between float and int/fixed

Correct the decoding of source and destination registers
for the VFP forms of the VCVT instructions which convert
between floating point and integer or fixed-point.

ARM: Fix decoding of Neon forms of VCVT between float and fixed point

Fix errors in the decoding of the Neon forms of fixed-point VCVT: * fixed-point VCVT is op 14 and 15, not 15 and 16 * the fbits immediate field was being misinterpreted * the sense of the to_fixed bit was inverted...

target-arm: Add support for PKHxx in thumb2

The PKHxx instructions were not recognized by the thumb2 decoder. The
solution provided in this changeset is identical to the arm-mode
implementation.

target-arm: Fix mixup in decoding of saturating add and sub

The thumb2 decoder contained a mixup between the bit controlling
doubling and the bit controlling if the operation was an add or a sub.

ARM: enable XScale/iWMMXT in linux-user mode

In linux-user mode, the XScale/iWMMXT coprocessors must be enabled
at reset so that we can run code that uses these instructions.

ARM: Expose vfp_get_fpscr() and vfp_set_fpscr() to C code

Expose the vfp_get_fpscr() and vfp_set_fpscr() functions to C
code as well as generated code, so we can use them to read and
write the FPSCR when saving and restoring VFP registers across
signal handlers in linux-user mode....

target-xxx: Use fprintf_function (format checking)

fprintf_function uses format checking with GCC_FMT_ATTR.

Format errors were fixed in
  • target-i386/helper.c
  • target-mips/translate.c
  • target-ppc/translate.c
