Subject: GDB RSP try 'p' before 'g'
Date: Wed, 24 Oct 2007 08:30:00 -0000	[thread overview]
Message-ID: <a0319f700710240129s5fb4ed61j223c683099d22c7f@mail.gmail.com> (raw)

Hello all,

    When doing remote debugging, GDB, version 6.0 and before, tries to
fetch the registers' value by 'g' packet when connected to remote
target. However, GDB version 6.4 and later, tries 'p' packet before 'g'
packet. So if the target supports 'p' packet, GDB uses 'p' packet to
retrieve value of all registers. That may degrate the speed for the poor
connection speed (Serial, parallel or even ethernet) between GDB and the
target.
    Does anybody know what is that change for?

Thanks.

Robert.
