target-mips: optimize gen_op_addr_add() (2/2)
Instead of dynamically generating different code depending on the UX flag, add a new flag in ctx->flags to generate different code. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5677 c046a42c-6fe2-441c-8c8c-71466251a162
