[Qemu-devel] [PATCH v3 00/11] tcg mips64 and mips r6 improvements

[Jin Guojie]

Changes since v2:
  * Update against master(v2.8.0-rc1)
  * Tested on Loongson as mips32r2(el) and mips64r2(el) hosts.
    Loongson only implements little-endian mips32/mips64 ISA.
  * Fully work for 32-bit and 64-bit guests.
    Fix two bugs：segmentation fault on mips64el with 32-bit guests,
                  blocking when emulating i386 kernel on mips64el.
  * Fix some minor style problems.
  * PATCH v2 12~16 are not examined due to the lack of R6 machine. 

To be tested:
  * big-endian mips32 and mips64 hosts.
    I have tried running qemu-system-mips on an X86. The speed is awful. 
    The compilation of qemu did not complete over a night until I gave up.
    A better way is needed to do this test.
  * MIPS R6.
