Subject: tcg/tci: Move call-return regs to end of tcg_target_reg_alloc_order
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=bcb81061dc8173076d9669f969d132b998cd2af9;p=qemu.git

tcg/tci: Move call-return regs to end of tcg_target_reg_alloc_order

As the only call-clobbered regs for TCI, these should
receive the least priority.
