[Qemu-devel] [PATCH] tile: Can load elf64 tilegx binary successfully for linux-user. |

After load elf64 tilegx binary for linux-user, the working flow reaches
the first correct instruction postion "__start". Next, we shall load all
instructions for qemu using.
This patch is based on Linux kernel tile architecture tilegx 64-bit
implementation, and also based on tilegx architecture ABI reference.
The related test:
address@hidden qemu]# ./configure --target-list=tile-linux-user && make
address@hidden qemu]# ./tile-linux-user/qemu-tile -d all ./test.tgx
