Hi Pedro,
I tested V3 on arm GNU/Linux and aarch64 GNU/Linux in both native and
gdbserver, there is no regression on arm GNU/Linux. There is one
regression on aarch64 GNU/Linux native, but I don't see how is this fail
related to your V3 patches. Note that there is no regression either on
aarch64 GNU/Linux with gdbserver.
