[Qemu-devel] [PATCH 1/1] tcg/tci: Remove unnecessary TODO() for INDEX_op_bswap16_i64

[Jaroslaw Pelczar]

Running Ubuntu with systemd on AArch64 Cortex-A53 and qemu is compiled

with

 

./configure --target-list=aarch64-softmmu --enable-tcg-interpreter

 

System gives the following log:

 

Welcome to Ubuntu 16.04.1 LTS!

 

systemd[1]: Set hostname to <localhost.localdomain>.

TODO (...)/qemu/tcg/tci.c:1049: tcg_qemu_tb_exec()

(...)/qemu/tcg/tci.c:1049: tcg fatal error

Aborted (core dumped)

 

After investigation it turns out that TCG generates bswap16_i64

opcode, which looks fine in the implementation.
