Either is fine with me. Basically, there are currently 3 switches for
demangling under H.J's binutils.
--[no-]demangle -- enables/disables demangling
--style -- set mangling style to a known demangling style like GNU, HP,
--demangler -- uses a demangler that is external to the tool to perform
So for example, to say I want to use "nm" and have it demangle using the
"HP" style, I do:
nm --demangle --style=HP.
I proposed to H.J. that we consolidate the --style swtich and the
--demangler switch and have the argument be overloaded. That if you say
"--demangler=HP" you get the HP demangler, but if you say
"--demangler=foo:bar" you get the external demangler looked up as foo
with the parameter bar.
I was wondering if it was further possible to fold the --demangle and the
--demangler switch together such that I could say "nm --demangle" and get
the default demangling or "nm --demangle=HP". Is this possible to do
within getopt? If I say "nm --demangle t.o", I do not want t.o be
interpreted as the optional argument. My understand of getopts is that if
an argument is optional, it must be provided in the --switch=arg form,
--switch form is disallowed. So this should work. So the documentation
--[no-]demangle[=<style>|<dso:function>] -- enable/disable demangling and
allows control over the demangling style using either a known style or an
external demangler. The default demangling style is GNU.
Phillippe, D.J. , Doug, since you guys objected to --style, would this be
