This would be my preferred solution, I know that tune files are already
quite complicated, but another variable which will

Its when using cortex-a5 tunes, -march=armv7-a -mcpu=cortex-a5, but if
we move the needle to fix the issue or test coverage then we miss the
point here, the fact that this keeps
Which -mcpu/-march combination is causing issue in gcc9?
I know we had this issue with armv7a tunes before, that's why I've added
separate armv7ve before the switch from -mtune to -mcpu.
I still believe -mcpu (with or without -march) is better option.
Using -mtune without indicating which

And what about machines which inherit an arch definition instead of a
cpu definition? Is that
tune files which inherit the arch definitions already define appropriate
-mcpu option, which is equivalent of right -march and -mtune combination
and is preferred since gcc is getting stricter and stricter with option
check semantics and can now find incompatible -march and -mcpu options
better
