Subject: 30.0.50; target warnings with gdb mode using gdb 13.2 + arm-cm4
Date: Tue, 20 Feb 2024 19:21:07 +0100

I'm debugging an arm core m4 target with gdb 13.2. When debugging 
this
target under `gdb' it spews the following warning:

 warning: Invalid state, unable to determine sp alias, assuming 
 msp.

This happens at every prompt, usually multiple times, in the main 
gdb
inferior buffer, making debugging pretty annoying as it breaks the
prompt:

 (gdb) warning: Invalid state, unable to determine sp alias, 
 assuming msp.
 warning: Invalid state, unable to determine sp alias, assuming 
 msp.
 warning: Invalid state, unable to determine sp alias, assuming 
 msp.

When I use gud-gdb instead there is no warning, but I loose some
functionality I wish I could use in gdb-mi.

Searching through gdb's source it seems that this warning is 
hardcoded,
but I have no clue exactly what command is being issue to cause 
it. When
I debug through gdb's prompt (without emacs) I actually can't see 
it.
