"right thing"? You have a very strange definition of "right". The x86 is
pretty much the only architecture still in use that passes everything on
the stack by default, and even there it's considered pretty painful (and
is not true of FP arguments).
If a debugger cannot handle arguments in registers, it by definition
cannot handle things like alpha/ppc/mips/xxx, so I'd say that the
debugger is seriously broken.
