    • rs6000: Initialise rs6000_cpu correctly (PR43871) · d78d986b 
      Finally, set rs6000_cpu based not on -mtune=, but only -mcpu= and the
defaults.


	PR target/43871
	* config/rs6000/rs6000.c (rs6000_option_override_internal): Set
	rs6000_cpu to the given -mcpu=, or to the default processor.

    • rs6000: Don't use rs6000_cpu_attr directly · 39f88700 
      In some places in the code we currently use rs6000_cpu_attr, although
that is a cast from rs6000_tune.  This patch changes things to be more
regular and clearer.  Now rs6000_cpu_attr is not used any more, and
it is deleted.


	* config/rs6000/rs6000.h (rs6000_cpu_attr): Delete.
	* config/rs6000/rs6000.c (rs6000_variable_issue_1): Use rs6000_tune

    • rs6000: Split rs6000_cpu · 793fa2a4 
      This splits rs6000_cpu into rs6000_cpu and rs6000_tune.  Both are still
initialised identically, so there is no behaviour change.

Now rs6000_cpu should be set by -mcpu=, and rs6000_tune by -mtune= (but
both still are set by -mtune=, fixed in a later patch in the series).

Also change rs6000_cpu to rs6000_tune in the appropriate cases (i.e.
most, but not those that enable using new insns).

	* config/rs6000/rs6000.c (rs6000_option_override_internal): Also set
