This mini-series removes the TARGET_LRA_P hook, forcing all targets
to use LRA.  I have not touched the targets that define -mlra
in terms of a 'Target Mask(XXX)' since IIRC there's no way to
"default" that.  I'd expect those to wrongly assume LRA isn't enabled
when using that XXX flag.  Likewise this defers removal of -mlra
and the TARGET_LRA_P hook from targets with a -mlra flag.

I'd appreciate target maintainers of targets with a -mlra to
enable LRA by default and unconditionally (aka, remove -mlra)
themselves.  Eventually that work will be done in a more-or-less
unchecked way later.

This RFC is first and foremost to remind people that the talk
to deprecate reload comes up repeatedly - I can find the last
proposal for GCC 13 and somehow remember we agreed to finally
go there for GCC 15, thus remove reload this stage1 though I
cannot find any such announcement.  There's still time to amend
gcc-15/changes.html though.

Jeff, I wonder if you can push 1/3 to your tester and verify
which targets get as far as building their [libgcc] target library
and thus would retain basic C language testing.


Richard Biener (3):
  Force targets to use LRA which opted out via hook_bool_void_false
  Flip default to LRA for targets with -mlra
  Remove TARGET_LRA_P hook
