Re: [RFC] Deprecate ARM FPA in GDB

Hi,
I propose to deprecate ARM FPA support in GDB.  The FPA
deprecation discussion was started in 2010 in GCC
https://gcc.gnu.org/ml/gcc/2010-05/msg00442.html and it was removed
in 2012 https://gcc.gnu.org/ml/gcc-patches/2012-06/msg00825.html

The deprecation means GDB no longer has options "fpa" and "softfpa" in
command "set arm fpu".  Currently, it is,

(gdb) set arm fpu
auto     fpa      softfpa  softvfp  vfp

I can't find GDB policy on deprecating code except
https://sourceware.org/gdb/wiki/Internals%20Obsoleting-code  What do I
need to do if I want to deprecate ARM FPA in 8.0 release?

The procedure described in the page you linked seems right. It gives chance to anyone still interested in the feature to come up and manifest themselves.

If you look at the archive of gdb-announce, there has been a few of such announcements. But again, not all removals of target support were announced on gdb-announce first (I am thinking of HP-UX for example). Instead of sending a message specifically about the removal of each feature, maybe we can just put a deprecation/removal notice in the next GDB release announcement. Then, the feature can be removed in master, in time for the following release.
