[Qemu-devel] [RFC] Configure option to turn on all debug printerfy

[Peter Crosthwaite]

So in a couple of cases now I have done work on mature device models
that include #ifdef'd debug printfery that is broken, and have
submitted (trivial) patches to fix. Whats happening is tree wide or
automated changes (changing types of variables etc) is causing the
debug printfery to break, usually werror issues on %x in printfs due
to types. Issue is, it never gets detected until someone tries to use
the debug mode: ./configure --extra-cflags="-DFOO_DEBUG". Can we have
some sort of alternate symbol "ALL_DEBUG" or something, such that
every debug printf is compiled? Then when developers make tree wide
changes they can at least compile test for breakages in debug printfs
using ./configure --extra-cflags="-DALL_DEBUG"? It would be fairly
trivial to implement.
