Subject: Help figuring out why `info registers` is showing <unavailable> with gdbserver target
Date: Wed, 2 Mar 2022 00:31:42 -0600 [thread overview]
Message-ID: <CAF8i9mOKTrJJ7acDeF9fLEHvnsZ8s-jCVPvTk+kt7ebDHxYjFg@mail.gmail.com> (raw)

Regarding this issue, support for gdbserver has been implemented here:
https://github.com/fontamsoc/binutils-gdb/blob/b2eeeae0/gdbserver/linux-pu32-low.cc
Support for gdb has been implemented here:
https://github.com/fontamsoc/binutils-gdb/blob/b2eeeae0/gdb/pu32-tdep.c
gdb is able to successfully connect to gdbserver and start a program
on the target; however, gdb is unable to fetch registers and instead
shows <unavailable> as follow:
(gdb) info registers
r0 <unavailable>
r1 <unavailable>
r2 <unavailable>
r3 <unavailable>
r4 <unavailable>
r5 <unavailable>
r6 <unavailable>
r7 <unavailable>
r8 <unavailable>
r9 <unavailable>
r10 <unavailable>
r11 <unavailable>
r12 <unavailable>
r13 <unavailable>
r14 <unavailable>
r15 <unavailable>
pc <unavailable>
Find attached full `gdbserver --debug --remote-debug` logs as well as gdb logs.
Any idea what might have been missed while implementing gdbserver support ?
Would you suggest ways to debug the issue ?
