Subject: accel/tcg/plugin: Avoid duplicate copy in copy_call
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ada4cb0c1cba89df3b00b6a92a6c1523c30f4396;p=qemu.git

accel/tcg/plugin: Avoid duplicate copy in copy_call

We copied all of the arguments in copy_op_nocheck.
We only need to replace the one argument that we change.
