This set of patches are about support displaced stepping of 16-bit Thumb instructions. There are much more 32-bit Thumb instructions than 16-bit Thumb instructions, so it takes more time to support 32-bit Thumb instructions. I'd like to send these three patches first to review. Once these three are done, it is straight forward to support 32-bit Thumb instructions. Regression tested these three patches along with another pending patch on armv7l-unknown-linux-gnueabi. http://sourceware.org/ml/gdb-patches/2010-12/msg00427.html No regressions and some test failures are fixed. -FAIL: gdb.base/moribund-step.exp: running to main in runto -FAIL: gdb.mi/mi-nonstop-exit.exp: mi runto main (timeout) -FAIL: gdb.mi/mi-nonstop.exp: mi runto main (timeout) -FAIL: gdb.mi/mi-ns-stale-regcache.exp: mi runto main (timeout) -FAIL: gdb.mi/mi-nsintrall.exp: mi runto main (timeout) -FAIL: gdb.mi/mi-nsmoribund.exp: mi runto main (timeout) -FAIL: gdb.mi/mi-nsthrexec.exp: mi runto main (timeout) -- Yao (齐尧)
