Actually only "Target CPU" (-mcpu) says that.
Here are two help strings:
"Target CPU"
Instruction and register set to use for generated code. Code will not
run on older processors. Only applies to GCC 3.3.
"Instruction Scheduling"
Optimize instruction scheduling for this CPU. Generated code will run
on older processors. Only applies to GCC 3.3.
(bold text is my doing)
However, in getting the strings out of the UI, I've run across a bug
that would explain why you might have been confused (the help text was
not being updated when performing a new search :(
