Subject: tcg-mips: Use T9 for TCG_TMP1
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f216a35f364df893519656648677a7629a36de9e;p=qemu.git

tcg-mips: Use T9 for TCG_TMP1

T0 is an argument register for the n32 and n64 abis.  T9 is the call
address register for the abis, and is more directly under the control
of the backend.
