[Bug driver/36731] New: "gcc -v" should include default arch/tune values

[vincent at vinc17 dot org]

"gcc -v" output should include default values corresponding to the -march and
-mtune options.

Works if you provide an (empty) input file:

echo | gcc -S -x c -v -

 /usr/lib/gcc/i486-linux-gnu/4.3.1/cc1 -quiet -v - -quiet -dumpbase -
-mtune=generic -auxbase - -version -o -.s

They do already via the configure options. I don't see this mentioned  
in the email though.

There's mtune, but not march. Also, most users probably don't know that.

Not here. Or perhaps one can deduce the value (how?), but that's not obvious
and not documented either.

That is a target specific decision. Really the default is either  
decided by the target maintainers or via the configure options. I say  
we should not worry about this bug really.
