Hi all,
For GCC 6 we want to deprecate architecture revisions prior to ARMv4T.
This patch implements this by documenting the deprecation in invoke.texi
and adding
a warning whenever the user specifies an -march or -mcpu option that
selects such
an architecture revision.
Bootstrapped and tested on arm.
Ok for trunk?
Thanks,
Kyrill
P.S. I'll add a note to changes.html to that effect separately.

* config/arm/arm.c (arm_option_override): Warn on pre-ARMv4T
architecture revisions.
* doc/invoke.texi (ARM Options): Add note on deprecation of pre-ARMv4T
architecture revisions.

* gcc.target/arm/ftest-armv4-arm.c: Add dg-warning for deprecation
warning.
* gcc.target/arm/pr62554.c: Likewise.
* gcc.target/arm/pr69610-1.c: Likewise.
* gcc.target/arm/pr69610-2.c: Likewise.
OK
After some offline discussion we've decided to not add an unconditional warning
every time someone
compiles for a deprecated architecture. This would irritate users.
As such, I'm just going to commit the invoke.texi hunk documenting the
deprecation.
Thanks,
