[Qemu-devel] [PATCH 0/6 v3] tilegx: Can load elf64 tilegx binary successfully for linux-user

[Chen Gang S]

After load elf64 tilegx binary for linux-user, the working flow reaches
1st correct instruction "__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]# ./tilegx-linux-user/qemu-tilegx -d all ./test.tgx
