Hmm. Works for me:
pm215@canth:/tmp$ wget http://wiki.qemu.org/download/qemu-0.15.0.tar.gz
[...]
pm215@canth:/tmp$ tar xzf qemu-0.15.0.tar.gz
pm215@canth:/tmp$ cd qemu-0.15.0/
pm215@canth:/tmp/qemu-0.15.0$ ./configure --target-list=arm-linux-user && make
-j4
[...]
pm215@c

The existing code looks OK to me -- there's no need to call
gen_set_CF_bit31() early because the inputs t0 and t1 to
gen_thumb2_data_op() should always be distinct TCG values, and so
gen_thumb2_data_op() will never trash t1. (There was a bug in this area
