Work log

In target_i386/cpu.h

• CPU86_LDouble  =:: struct { uint64_t low, uint16_t high; }

Note:

• x86 versions of perlbench - arith.t and omnetpp fail to run on ARM with QEMU-0.13 official version but run successfully in QEMU-1.1.1
• I tried two compiler : gcc-4.7 and gcc-4.4
• The reason is that QEMU does not use CONFIG_SOFTFLOAT for i386 target, even when host is ARM. As a result, QEMU uses only 64-bit double for x86 80-bit floating point registers.
• This is strange! I never heard DY report that he fails to run omnetpp, or perlbench.
• Others can now run test inputs successfully
• Plan to port LnQ to QEMU 1.2 + LLVM 3.2。
• Correctness is far important than Performance!!!!!
