ChangeLog must just describe the what, nothing more.  If the rationale is not
obvious, then a comment must be added _in the code_ itself.

	* config/sparc/sparc.c (sparc_function_value_regno_p): Do not return
	true on %f0 for a target without FPU.
	* config/sparc/sparc.md (untyped_call): Do not save %f0 for a target
	without FPU.
	(untyped_return): Do not load %f0 for a target without FPU.

Understood. Thank you for looking at my patches and coming withimprovements.
