target-arm: fix neon vshrn/vrshrn ops

In the existing code shift value is clobbered during the pass loop.
This patch changes the code so that it stores the intermediate
result in the target neon register directly and eliminates the need
to use a temporary to hold the intermediate value thus leaving the...

target-arm: add support for neon vld1.64/vst1.64 instructions

Add support for NEON vld1.64 and vst1.64 instructions. This patch is
revised to follow more closely the specification and raises
undefined exception if 64bit element size is used for vld2/vst2 or...

target-arm: allow modifying vfp fpexc en bit only

All other bits except for the EN in the VFP FPEXC register are defined
as subarchitecture specific and real functionality for any of the
other bits has not been implemented in QEMU. However, current code
allows modifying all bits in the VFP FPEXC register leading to...

target-arm: fix neon vsri, vshl and vsli ops

Shift by immediate value is incorrectly overwritten by a temporary
variable in the processing of NEON vsri, vshl and vsli instructions.
This patch has been revised to also include a fix for the special
case where the code would previously try to shift an integer value...

target-arm: fix neon shift helper functions

Current code is broken at least on recent compilers, comparison
between signed and unsigned types yield incorrect code and render
the neon shift helper functions defunct. This is the third revision
of this patch, casting all comparisons with the sizeof operator to...

target-arm: fix incorrect temporary variable freeing

tmp4 and tmp5 temporary variables are allocated using tcg_const_i32
but incorrectly released using dead_tmp which will cause resource
leak tracking to report false leaks.

target-arm: optimize thumb 32-bit multiply

Current implementation of thumb mul instruction is implemented as a
32x32->64 multiply which then uses only 32 least significant bits of
the result. Replace that with a simple 32x32->32 multiply.

target-arm: cleanup internal resource leaks

Revised patch for getting rid of tcg temporary variable leaks in
target-arm/translate.c. This version also includes the leak patch for
gen_set_cpsr macro, now converted as a static inline function, which I
sent earlier as a separate patch on top of this patch....

target-arm: fix sdiv helper

(INT32_MIN / -1) triggers an overflow, and the result depends on the
host architecture (INT32_MIN on arm, -1 on ppc, SIGFPE on x86). Use a
test to output the correct value.
